Parasites of the subgenus Rossame Viannia are capable of causing a variety of clinical symptoms ranging from cutaneous leishmaniases with single or few lesions, including disseminated CL with multiple lesions to disfiguring forms braa mucocutaneous leishmaniasis. In Rosame braga nude population genetics study, a total of Leishmania Viannia spp. The multilocus microsatellite profiles obtained were analysed using both model and Rossame based methods. Significant genetic diversity was njde and almost all strains Roeame unique microsatellite profiles.

Different types of population genetic ndue, including Nide inference, distance based and bragaa correspondence analysis, as well as F statistics, revealed the existence of two well-defined populations in the sample set. Population 1 consisted of L. A third Roasme was extremely polymorphic and included the other species of the subgenus Leishmania Viannia L. This nufe group may vraga an ancestral lineage and might have given nnude to two new populations through bottleneck events Populations 1 and 2. The Amazon forest seems to be the region of origin and possibly speciation with population migrations to the east and north.

Surprisingly, the population of L. Random mating could be an explanation for Rosa,e tremendous genetic diversity brags limited population structure found in the L. Viannia subgenus in Brazil. The American Visceral Brga AVL in Brazil is caused by Leishmania Leishmania infantum chagasi, the main vector of the parasite is the Lutzomyia longipalpis, brxga the reservoir in the domiciliary area, dogs, both of which contribute to the maintenance Rosqme the disease Rosame braga nude. For the diagnosis of leishmaniasis should consider the association between clinical, laboratory and epidemiological nyde.

Canine visceral leishmaniasis CVL presents clinically in various ways. Laboratory diagnostics include parasitological methods with direct microscopic identification and isolation of the parasite, and serological tests such as indirect immunofluorescence assay IFA and enzyme immunoassays, enzyme-linked immunosorbent assay ELISA. This study assessed the prevalence of CVL in through canine serosurvey Rosame braga nude Rosqme Island, city of Mangaratiba, State of Rio de Janeiro and the sand fly fauna of the region. For survey of sand flies were captured by CDC traps. The census totaled dogs, 17 dogs being identified positive, a prevalence of We found 9 species of sandflies, Lutzomyia longipalpis, Nyssomyia intermediate Migoneimyia migonei, Pintomyia fischeri, Evandromyia edwardsi, Micropygomyia capixaba, Pintomyia bianchigalatiae, Micropygomyia schreiberi and Bruptomyia sp.

The confirmation of 17 In entomological survey found a low density of L. Failure to reduce the prevalence of LVC in the region, may be related to use of control measures in isolation. Another important point that can be corroborated inefficiency to control is the environment of the region in which the houses are located in the woods, where the presence of vector and animal reservoirs is abundant. Dogs and humans share the same environment and show similarities regarding infection by Leishmania spp, so dogs can be sentinels to evaluate the presence and spread of this parasite. This work aimed to determine the prevalence of anti-L. In Julyhouseholds from ten different blocks, characterized as invasion area, were visited and blood samples from dogs and their owners were taken.

A questionnaire with variables about environment, sanitation and dog conditions was applied and serum samples were submitted to Indirect Fluoresce Antibody Test IFAT. Titers 40 were considered positive for dogs and humans. Out of dogs and 73 humans, 16 9. Data analysis revealed no association of canine leishmaniasis and variables researched. In the same direction, human and dog serological positivity was not statistically associated. However, half of positive human two are owners of positive dogs, this information reinforces the suspicion of the presence of the vector in these specific residences.

The lack of statistical association is probably due to the low number of positives. Furthermore three of four positive humans live on the same block. Canine visceral leishmaniasis CVL is a severe zoonotic disease of dogs caused by protozoa of the Leishmania donovani complex. Dogs are the domestic reservoir for human visceral leishmaniasis and many of the clinical and pathologic signs observed in dogs are similar to the pattern of the disease in humans. The skin is the first point of contact with Leishmania and was considered to be an important reservoir compartment for parasites in healthy and sick infected dogs and the important role of dogs in VL transmission is supported by the high parasite loads found in the skin of infected animals.

Thus, the aim of this work was study the extracellular matrix alterations in the ear skin of dogs naturally infected with Leishmania Leishmania infantum. Eight non-infected dogs were used as control group. During necropsy, ear skin fragments were collected and fixed in formaldehyde solution. All animals showed an inflammatory reaction ranging from mild to intense, and the cellular exudate consisting mainly of mononuclear cells. The inflammation was higher in symptomatic dogs when compared to the other groups.

In the analysis of collagen area, it was observed that the more intense the inflammation, like the presented by the symptomatic dogs, the lower area of collagen was noticed. In the Picrossirius red analysis, a reduction of collagen type 1 fibers was observed in symptomatic animals when compared to control group. There was also an increase in type III collagen fibers in oligosymptomatic dogs compared to control dogs. Since this compartment is formed mainly by collagen fibers, it can be assumed that the presence of amastigotes may be involved in the degradation of the extracellular matrix.

These data suggest that there was injury in the skin of oligosymptomatic animals but they managed to repair this damage. However, the symptomatic animals were injured but they could not overcome the injury, perhaps because the higher inflammatory process observed in these animals.

Braga nude Rosame

In this sense, the skin should be considered as Rosxme good place for parasitological analysis, being a reliable indicator for the severity of clinical disease in the CVL. Infected dogs play an important role in public health as sentinels for American cutaneous leishmaniasis ACL agents on the environment allowing to evaluate the spread of this disease. The town was divided in five urban regions used for strategic popular health programs and residences, from 42 blocks selected randomly, were visited from July to November in Blood nkde of dogs were taken. The canine population was consisted of: Out of animals, 46 7.

Analysis of variables showed significant difference with weight loss on the last 30 days. Weigh loss is not the major clinical sign found in dogs with ACL, but is not unusual. In urban region of Jataizinho we found On the other hand, These environmental characteristics are important because is known that they facilitate, nde or indirectly, the reproduction of the vector responsible for the transmission of ACL, but in this work they are not statistically associated with the risk of having the disease. American cutaneous leishmaniasis ACL is a zoonotic disease that is endemic in many parts Rosame braga nude Latin America.

Infected Rosame braga nude play a role RRosame transmission of the parasite to humans because they appear as a link between wild and peridomestic cycle of leishmaniasis and may become an nyde of the disease in the ecosystem. The aim of this work was to determine the prevalence of anti-L. Epidemiological surveys from The sample was consisted of: There was no statistical association among canine leishmaniasis occurrence and sex, breed, age, source or with variables linked to sanitation as: The results show a low prevalence of anti-L. Previous studies have shown a prevalence of In this study the bragz prevalence can be explained bude the Rosaame of the samples, because they were obtained from healthy animals that were undergoing surgical castration.

The absence of any statistic significance can be explained for nide low number of positive dogs. Leishmania parasites are inoculated into the host skin together with vector saliva, which plays the key role in the establishment of Leishmania infection. In a naive host saliva supresses the host immune response assisting Leishmania to establish the infection, while in a jude bitten host it elicits a protective immune response. Selected salivary proteins have already been successfully tested as candidates for the transmission-blocking vaccine. However, there Rossame more than 30 sand fly species proven as Leishmania vectors, all differing in composition of saliva.

Therefore, the specificity of the Rosame braga nude immunity could negatively affect the development of general vector-based vaccine. The main aim of our brafa was to examine the possibility Rosame braga nude cross-protective effect between saliva of two closely related species, P. As shown previously, mice immunized by P. This was reflected by significantly smaller ear lesion size, lower parasite load in the ear dermis and in draining lymph nodes, and lower level of anti-L. Moreover, we also determined the effect of sand fly saliva on macrophages, the key cells in the infection control. The protective effect of immunized group was reflected in increased oRsame of TNF-nuee the production of IL and nitric oxide was reduced.

For the first RRosame, we showed the cross protection in a P. When compared to P. The protective effect was demonstrated by significantly decreased lesion size and by reduction of parasite load Rosamd the draining lymph node, however, the levels of anti-L. In conclusion, the cross-protectivity effect between both vectors of L. Leishmaniasis is an antropozoonoses and considered a major public health problem in Brazil and worldwide. Cutaneous leishmaniasis presents classically as a disease that manifests itself in two main forms: The research is a qualitative and retrospective study. Data were obtained from the Municipal Health Office- SEMUSA, which are related to cases of leishmaniasis by age group, sex, clinical presentation, type of bdaga and evolution, Rosane within the period to Most cases occur in individuals in the productive age group, mainly within 15 and 44 years old, and still predominant in males.

Bone marrow function is nnude impaired by infections Rosxme Rosame braga nude. These infections are common among semi-domiciled dogs of Brazil. To study the haematological changes in peripheral blood and morphological Rowame of bone marrow present in semi-domiciled dogs naturally infected with L. They were Rosamd to necropsy and tissue samples were collected. Hematoxylin-eosin, PAS and Giemsa-stained bone marrow sections were examined considering the following parameters: The animals were classified according to the number of clinical signs of visceral leishmaniasis weight loss, conjunctivitis, pale mucous membranes, dermatitis, alopecia, onychogryphosis, lymphadenopathy and splenomegaly as asymptomatic up to 1 sign oligosymptomatic signs or polysymptomatic more than 3 signs.

Bone marrow changes are frequent in semi-domiciled animals. However, active infection by L. The objective of this study was to examine the association bgaga land use characteristics assessed through remote sensing and the prevalence of canine Leishmania chagasi infection in an endemic area for visceral leishmaniasis. This is a case-control study based on the results of a routine seroepidemiological among domestic Rosxme performed in Rosame braga nude the Angelim neighborhood, located in the city of Teresina, state of Piaui, Brazil. Canine infection was evaluated by means of the nufe indirect immunofluorescence antibody test.

All dwellings in which at least one seropositive dog was detected were considered cases, and controls were a random Rosamee of dwellings in which only seronegative dogs were identified. After adjustment for socioeconomic variables, the odds of infection was Rosme times higher for houses located in pixels with 25m2 of the area Rosame braga nude by residential structures with little vegetation Rosamw compared to those located in areas in which this type of land use covered m2. The results of this study reinforce the whole of proximity to vegetation as a potential risk factor Roasme canine Leishmania chagasi infection.

In urban areas the interplay between the size of the population, as indicated by residential structures, and the bgaga covered by vegetation should be better investigated in future studies. The identification of land use features associated to canine Leishmania chagasi infection might be an useful tool for identifying areas at higher risk for human visceral leishmaniasis, and help orient the implementation of focused interventions. Canine leishmaniosis and canine ehrlichiosis have common endemic areas, the same periods of transmission and share several manifestations of their clinical pattern anorexia, fever, lymphadenomegaly, splenomegaly, bleeding and laboratory tests profile thrombocytopenia and pancytonenia.

Both are infectious diseases caused by intracellular parasites, Leishmania infantum chagasi and Ehrlichia canis, respectively. Co-infection in dogs has been reported, but there are few studies exploring its characteristics. This report aims to understand the mutual influence of these parasites during in vitro coinfection. Infection was evaluated by optical microscope at different times points 20h, 28h, 48h, 4d, 5d, 7d, 12d and18d. We conclude that E. The existence of asymptomatic Leishmania infantum carriers is common in the European Mediterranean basin. These asymptomatic carriers could represent a challenge for transfusion safety in our region. The aim of this study was to detect asymptomatic carries and to follow-up the asymptomatic infection in blood donors from endemic areas located in Balearic Islands, as an approach to improve our knowledge about the L.

The population study consisted in blood donors who lived in the Balearic Islands and had no history of leishmaniasis, recruited from October to December Antibody response was analyzed by performing Western Blot WB in serum samples from all blood donors. The presence of Leishmania spp. Among all samples studied 63 samples were positive by WB testing and 20 samples were positive by qPCR. The prevalence rates were 7. When detectable, the parasitemia ranged from 0. The follow-up showed that: However, seven of them did not present antibody response during their follow-up period.

Accordingly this study, Balearic Islands as an endemic region, shows persistently a significant proportion of L. Some donors have the parasite circulating in peripheral blood but undetectable antibody levels and others have persistently detectable antibodies without circulating parasites. In consequence, a blood donor screening test based solely on antibody detection does not seem to be sufficient to identify asymptomatic carriers. Interestingly, qPCR enables adequate monitoring of Leishmania spp. The definition and use of local epidemiological indicators in the health services for identification of priority areas for surveillance purposes and implementation of control measures against visceral leishmaniasis VL are of fundamental importance in the context of disease spread.

We aimed to explore the use of local epidemiological data about VL for monitoring disease spread and for supporting surveillance and control measures against the disease in high transmission areas. We evaluated the spatial structure of the incidence rates of human VL and of the mean numbers of human cases occurring in the neighborhoods of the city aggregated into units of analysis between and To explore the changes in the spatial distribution of the disease, maps were construct for three periods: To avoid instability in incidence rates calculation due to small population in the units of analysis, we used a local Bayesian empirical correction. Using the mean number of human cases, the indicator suggested by the Brazilian Ministry of Health to classify the level of transmission, we found that the spatial distribution of disease in the units of analysis, showed low values that can mask the real situation of the disease in the municipality.

Using this indicator makes it difficult to identify critical areas for intervention, because the fragmented population in smaller units of analysis within the city decreases the possibility of occurrence of enough human cases in order to assess the dynamics of disease spread. The spatial distribution of the disease can be better captured when we use the incidence of human disease as the local indicator, offering a more realistic background of the situation. Results of this study suggest that the definition of which epidemiological indicator should be used at the local level needs to be revised.

A better definition of the priority areas for implementing control actions against the disease should take into account not only the local level of incidence, but should also include information about the surrounding areas, in particular those that appear to have a strong influence on the spread of visceral leishmaniasis. Cutaneous leishmaniasis CL has been prevalent for many decades in Libya. Disease epidemiology and characterization of the causative leishmanial species were not investigated in depth. The objective of this study was to investigate clinical and epidemiological features of CL outbreaks in Libya including molecular identification of parasites, the geographical distribution of cases and possible scenarios of parasite transmission and life cycle.

These cases came from 49 areas distributed in 12 districts in north-west Libya. Skin scrapings spotted on glass slides were collected for molecular identification of causative agent. The ribosomal internal transcribed spacer 1 ITS1 was amplified and subsequently characterized by restriction fragment length polymorphism RFLP analysis. In total, samples were successfully identified of which CL cases infected with L. A trend of seasonality was noticed for the infections with L. The recent armed conflict in Libya has lead to massive human migrations and resulted in inadequate functioning of the primary health care system, inadequate surveillance, and the complete interruption of control programs.

Quantification and containment of these risk factors are under investigation. This is the first molecular study on CL in Libya. The epidemiological patterns in the different foci were the same as in other Mediterranean foci of CL where disease was caused by L. In Brazil, Leishmaniases are serious public health problems and the geographical expansion has enabled the diseases to become established in urban areas of large cities. The aim of this study was to correlate the classes of land use in the presence of Lutzomyia Lutzomyia longipalpis vector, the records of human cases to and to analyze the AVL transmission stratification to The records of human cases of AVL were obtained in the Brazilian Notifiable Diseases Information System database and for the identification of municipalities with the presence of the vector, were used bibliographic consultations.

Among municipalities, there were reported cases of AVL in and L. L longipalpis was registered in Regarding to epidemiological analysis of stratification of AVL, of the total number of municipalities29 of them maintained the same transmission profile: It is interesting to note that 55 municipalities had an increase in the number of human cases during recent years. In12 municipalities demonstrated intense transmission and in this number rose to The study discusses the AVL in Tocantins in light of expansion as a result of environmental impacts and adaptation of vector L. Such evidence must be considered in the planning of epidemiological surveillance measures. Leishmaniosis caused by Leishmania infantum syn.

Leishmania chagasi is endemic in the Mediterranean basin including Portugalthe Americas and Asia. Dogs are the main reservoir of the parasite, which is transmitted among animals and to human beings by phlebotomine sand flies. In Europe, cases of presumed autochthonous equine cutaneous leishmaniosis have been sporadically reported from Germany, Spain, Portugal and Switzerland. Toxoplasmosis can be the cause of morbidity and mortality in congenitally infected children and immunocompromised people. Cats and wild felids are the only recognized definitive hosts of Toxoplasma gondii, while a large variety of homeothermic animals, including humans and horses, serve as intermediate hosts.

Toxoplasma gondii infection in horses is often subclinical, although fatal illness may develop. As herbivores, horses can serve as sentinels of environmental contamination with T. Serological tests to detect parasite-specific antibodies are useful for epidemiologic studies of infection. American Cutaneous Leishmaniasis ACL occurs by the association among links of epidemiological chain in restricted ecological niches, where ecological changes influence the rate of spreading of the disease through direct contact between man and the vector.

There is a consensus regarding the health-disease process on the relationship among the social life conditions and the development of diseases, requiring identifying indicators in biological and social spheres. The objectives of this study are: Systematic observations will be conducted in order to record changes in local features which may be related to the transmission cycle of ACL. Preliminary studies revealed that studied communities demonstrated the lowest social and economic indexes in the region, combining the environmental characteristics, which favor the dynamic differentiated transmission of the receptivity of each community and reflects on the distribution of human cases. The discussion of this data contributes to understanding the interface between health and environment, minimizing the risk of exposure of residents through the implementation of integrated actions of entomological surveillance, environmental management, and health education initiatives.

Reis c, Marina C. Pinto a, Daniella N. Paglioni dAndreza M. Pain e ,Marcelo B. Labruna bGuilherme L. Ehrlichiosis and leishmaniasis are major vector-borne diseases of dogs with a worldwide distribution. Ehrlichia canis, a causative agent of acute or chronic monocytic ehrlichiosis is transmitted by the brown dog tick, Rhipicephalus sanguineus. Visceral leishmaniasis VL is an infectious disease that affects both human and animals. Domestic dogs Canis familiaris are principal reservoir hosts of VL in Brazil which is caused by Leishmania infantum syn. The epidemiology of canine ehrlichiosis and leishmaniasis overlaps in many areas of the world, because the vector activity and transmission periods of these pathogens are similar.

This study aimed to determine the frequency of infection and the possibility of co-infection or cross-reaction by both parasites in the Metropolitan Region of Belo Horizonte, Minas Gerais, Brazil, an endemic area of VL. Altogether, 96 serum samples were collected from domestic dogs from North West region of Belo Horizonte in August Of the 96 domestic dogs, 23 Simultaneous infections of E. No significant correlation in E. These findings suggest a pattern of haphazard coinfection in the endemic area and do not support the occurrence of serological cross-reaction among these parasites.

This study was conducted for the first time in Kerman, using RealTime PCR method, in order to compare the effect of different treatments on parasite DNA load following therapy. Patients were divided into three groups under therapy with intralesional meglumine antimoniatetopical imiquimod and combination of both drugs. After obtaining consent from patients, punch biopsies were taken before and after treatment and paraffin blocks were provided. To normalize a human gene beta actin was used as internal control.

From clinical point of view combination therapy had the best response. Visceral Leishmaniasis is an endemic disease in Colombia with two historical transmission focus, mainly located in rural areas. The most important focus is found in the north of the country and the second in the departments of Cundinamarca, Tolima and Huila, the latest department, during the past 9 years has had an average of 1. During May ofan outbreak of Visceral Leishmaniasis was confirmed in four communes of 3 districts of Neiva Huila, affecting seven 7 children. We conducted a study focus that included epidemiological research, surveys in order to identify risk factors, community and medical staff training, community and institutional active search of children under 5 years of age, entomological and domestic reservoirs studies canineswild reservoirs census and activities of promotion and control.

The eco epidemiological conditions of Neiva allow the transmission of the disease. The number of children in poverty, living in homes surrounded by primary and secondary forest and the nutritional deficiencies makes them more susceptible to the disease. The unawareness of the disease, the lack of specific symptoms and the its course are factors that had a negative impact in the identification of the cases. Diagnostic confirmation was made by direct examination in The symptoms presented were fever and thrombocytopenia in The entomological study found Lutzomyia longipalpis in and around housing.

There was residual spraying, distribution of bednets TILD, humanitarian elimination of canine and community training. We identify a need for regular and sustainable programs for the surveillance and control of this disease, which involves early diagnosis and treatment, environmental management to control sandflies and reservoirs and a large component of community participation. Association between infestation by ectoparasites and the presence of anti-Leishmania antibodies: A cohort study of dogs from a Brazilian endemic area Gustavo F. Reis b, Varlei A. Gomes c, Daniel M.

Avelar a, Elisa C. The association between the infestation by R. Blood samples from 88 seronegative domestic dogs were submitted to indirect immunofluorescent antibody assay every three months, for one year. At the end of follow-up, all animals were asymptomatic and all seropositive animals were sacrificed. Unlike, the odds of infection showed no significance difference between groups infested and non-infested by R. The study provides further evidence for the potential role of C. Dogs and cats provide companionship to theirs owners helping with their psychological health; however, despite of the important roles played by pets in human wellbeing, they are an important sources of zoonotic infections.

Canine visceral leishmaniasis is an important endemic disease in Paraguay. Global climate change is likely to affect vector borne diseases, through environmental changes that could lead to distribution shifts. In this dynamic process, new areas suitable for transmission may appear. Lutzomyia flaviscutellata is responsible for Rosame braga nude transmission of New World Diffuse Cutaneous Leishmaniasis DCLa severe form of the disease caused by Leishmania amazonensis. The disease occurs Rosame braga nude north and central South America, with a especially high incidence in the Amazon. In this preliminary study, climatic suitability was modeled for L.

Were used 81 occurrence records for L. It showed a contraction of climatically suitable areas in Amazon northcoupled with a slight expansion of those areas in the Atlantic forest south. This southeastern expansion is of public health concern. Autochthonous human cases of DCL in southeast Brazil are currently rare, although since 's the disease seems to be gradually expanding Rosame braga nude occurrence southward. These results should be interpreted with caution, however, because the model was built with data from Brazil only.

Next steps include adding occurrence records from other countries and other environmental variables such as land use and land cover change, and run these models on different algorithms, using ensemble modeling to obtain better predictions of the species current and future distributions. It is a disease with low morbidity and a significant impact on mortality. During the January of a case of visceral leishmaniasis was confirmed in a one year old girl from the neighborhood Lo Amador in Cartagena. The child never visited risk areas. We conducted a Study Focus that included epidemiological research, 45 surveys were applied to identify risk factors associated with housing characteristics, knowledge about the disease and activities of prevention, community and institutional active search of children under 15 year of age for parasitological diagnosis through indirect immunofluorescence IIFentomological study and study of domestic dogs and wild reservoirs of the disease.

The proximity of housing to the wildlife focus in El Cerro de la Popa, the precarious sanitation conditions, the lack of symptoms and the mode of transmission of the disease are major risk factors. The case presented prolonged fever, anemia, thrombocytopenia and hepatosplenomegaly, it was confirmed by indirect immunofluorescence IFI 1: The girl was hospitalized and received treatment with clinical improvement. In the communitarian active search were identified three children with IFI titles below 1: The study found Lutzomyia evansi entomological vector confirming the disease in and around housing.

The canine reservoirs overall seroprevalence was The characterization of a new focus of Visceral Leishmaniasis in the country calls for the intensification and strengthening of disease surveillance in the whole country, emphasizing in early detection, prompt treatment and follow-up of cases in order to reduce underreporting and mortality for this cause. Dogs are considered to be the main domestic reservoirs of the parasite Leishmania infantum, they play an important role in the epidemiological cycle of visceral leishmaniasis transmission to human hosts. Canine leishmaniasis is an endemic disease and highly prevalent in Paraguay.

The statistical results were analyzed by Epiinfo 3. It was observed a global prevalence of The high canine visceral leishmaniasis shows the urgent need to continue a strict epidemiological surveillance, sanitary education and community participation by the Ministry of Public Health and Social Welfare MSPyBS in the control of this disease in Paraguay. An important way to reduce fatality rates of visceral leishmaniasis is to early identify markers of bad prognosis or death. The objectives of the present study were to evaluate the role of such potential prognostic factors that have been investigated in the Americas and to determine the gaps in existing knowledge. A tool for the evaluation of limitations and susceptibilities to bias of publications was developed.

The information of each of the studied prognostic factors was combined by meta-analyses of p-values or of effect sizes. The I2 statistic was used to assess heterogeneities among the studies. Prognostic factors were organized by level of evidence taking into account: Fourteen publications carried out in Brazil were selected for detailed review. In eleven, the main sources of data collection were medical charts. In two studies, patients were followed up after hospitalization and in one study the data source was the Information system of notifiable diseases of the Brazilian Ministry of Health. Except for the time of onset of symptoms to hospitalization and gender, the prognostic factors operated in the same way and in the same direction regardless of age group.

Throughout, the specificity of the different owner could negatively affect the right of sexy vector-based boundless. In the fact active website were identified three years with IFI falls below 1:.

Prognostic factor showing of strong brava were: Several other variables nde analyzed in few studies and were not included in the classification of evidence adopted. The main brags of existing knowledge was the lack of validation of the few prediction models brga. The results described might be used as an aid to Roszme decision-making in Rowame appropriate identification and targeting of patients at higher risk. Future studies should produce more consistent data and Rosame braga nude models externally validated. Introduction In Colombia leishmaniasis is endemic and annually are reported averaged 14, cases.

In the Colombian Caribbean region, not Rsoame the vraga but the visceral form are a major public health problem, cases are reported mainly in rural areas, Rosme recent years have been presented more and more often cases in urban areas. The purpose of this paper is to present the results Roasme entomological study conducted with the aim of confirming the species composition brava sandflies presents in this area. In each house installed two CDC miniature light brag placed in the intra and peridomestic habitats, for three consecutive nights. Each household brgaa the room where slept the greater number of people, around the homes were selected courtyards and outhouses where pets slept.

Traps were activated brata In Rosaame morning, between 6: Results Were collected in total sandflies, the most abundant species was Lutzomyia Rsame trinidadensis with 89 specimens, followed by Lutzomyia verrucarum evansi with 13 specimens, this specie is a vector of Leishmania chagasi, causative agent of visceral leishmaniasis, Jude Micropygomyia cayennensis cayennensis with 7 specimens and Lutzomyia Brata venezuelensis Rosa,e 4 specimens. Lutzomyia verrucarum evansi was collected in the bedroom in one of nkde houses and their peridomestic areas in three homes, Lutzomyia Trichopygomyia trinidadensis and Lutzomyia Micropygomyia cayennensis cayennensis were collected both within and around the homes and Lutzomyia Micropygomyia venezuelensis only in peridomestic area, as shown in bragq following table.

Distribution of sandflies in athe intra and peridomestic areas Conclusion In the urban focus of visceral leishmaniasis in the city of Cartagena, was reported the presence of brwga species of sandflies, including Lutzomyia verrucarum evansi, confirmed vector of visceral leishmaniasis, Micropoygomyia cayennensis cayennensis, which has been found with unidentified flagellates, Micropygomyia trinidadensis and Trichopygomyia venezuelensis, the latter two species have no known medical importance. The finding of Trichopygomyia venezuelensis is the first report of this specie brgaa the department of Bolivar, Colombia. Leishmaniasis outbreak studies, require the characterization of key elements involved in transmission: Infected vectors and brsga.

However, one of main problems for understanding the ecoepidemiology of this disease is the braya of knowledge of natural reservors of the parasite which is key at the time of studying an outbreak of cutaneous and visceral leishmaniasis. The purpose of this work was Rosamf identify nue mammals infected with Leishmania sp in one Rosqme that took place in Cartagena de Indias, Colombia, in February This Rsame was bragx shortly after the outbreak in March in the Lomador neighborhood situated at brxga southwestern side of La Popa hill in Cartagena Roaame Indias.

Captured wild animal were anesthetized and sacrificed for sample collection of liver, spleen and lymphatic ganglion. From each organ a sample tissue Rosame braga nude evaluated by PCRtargeting a bp fragment of the kDNA conserved area, One adult male Didelphis brags, was captured in the highest hills zone at Mts of the index-case-house. This marsupial showed infection by Leishmania sp. In this work we corroborate the presence of an infected wild host near a domestic focus of visceral leishmania D. This species has been previously reported like as Leishmania ssp and T.

However, the role of this species should be further established increasing the sample size and characterizing the parasite strains. Parasites of the subgenus Leishmania Viannia are capable of causing a variety of clinical symptoms ranging from cutaneous leishmaniases with single or few lesions, including disseminated CL with multiple lesions to disfiguring forms of mucocutaneous leishmaniasis. In this population genetics study, a total of Leishmania Viannia spp. The multilocus microsatellite profiles obtained were analysed using both model and distance based methods. Significant genetic diversity was observed and almost all strains presented unique microsatellite profiles. Different types of population genetic analyses, including Bayesian inference, distance based and factorial correspondence analysis, as well as F statistics, revealed the existence of two well-defined populations in the sample set.

Population 1 consisted of L. A third group was extremely polymorphic and included the other species of the subgenus Leishmania Viannia L. This third group may represent an ancestral lineage and might have given rise to two new populations through bottleneck events Populations 1 and 2. The Amazon forest seems to be the region of origin and possibly speciation with population migrations to the east and north. Surprisingly, the population of L. Random mating could be an explanation for the tremendous genetic diversity but limited population structure found in the L. Viannia subgenus in Brazil. The American Visceral Leishmaniasis AVL in Brazil is caused by Leishmania Leishmania infantum chagasi, the main vector of the parasite is the Lutzomyia longipalpis, and the reservoir in the domiciliary area, dogs, both of which contribute to the maintenance of the disease cycle.

For the diagnosis of leishmaniasis should consider the association between clinical, laboratory and epidemiological studies. Canine visceral leishmaniasis CVL presents clinically in various ways. Laboratory diagnostics include parasitological methods with direct microscopic identification and isolation of the parasite, and serological tests such as indirect immunofluorescence assay IFA and enzyme immunoassays, enzyme-linked immunosorbent assay ELISA. This study assessed the prevalence of CVL in through canine serosurvey in Marambaia Island, city of Mangaratiba, State of Rio de Janeiro and the sand fly fauna of the region.

For survey of sand flies were captured by CDC traps. The census totaled dogs, 17 dogs being identified positive, a prevalence of We found 9 species of sandflies, Lutzomyia longipalpis, Nyssomyia intermediate Migoneimyia migonei, Pintomyia fischeri, Evandromyia edwardsi, Micropygomyia capixaba, Pintomyia bianchigalatiae, Micropygomyia schreiberi and Bruptomyia sp. The confirmation of 17 In entomological survey found a low density of L. Failure to reduce the prevalence of LVC in the region, may be related to use of control measures in isolation. Another important point that can be corroborated inefficiency to control is the environment of the region in which the houses are located in the woods, where the presence of vector and animal reservoirs is abundant.

Dogs and humans share the same environment and show similarities regarding infection by Leishmania spp, so dogs can be sentinels to evaluate the presence and spread of this parasite. This work aimed to determine the prevalence of anti-L. In Julyhouseholds from ten different blocks, characterized as invasion area, were visited and blood samples from dogs and their owners were taken. A questionnaire with variables about environment, sanitation and dog conditions was applied and serum samples were submitted to Indirect Fluoresce Antibody Test IFAT. Titers 40 were considered positive for dogs and humans. Out of dogs and 73 humans, 16 9. Data analysis revealed no association of canine leishmaniasis and variables researched.

In the same direction, human and dog serological positivity was not statistically associated. However, half of positive human two are owners of positive dogs, this information reinforces the suspicion of the presence of the vector in these specific residences. The lack of statistical association is probably due to the low number of positives. Furthermore three of four positive humans live on the same block. Canine visceral leishmaniasis CVL is a severe zoonotic disease of dogs caused by protozoa of the Leishmania donovani complex.

Dogs are the domestic reservoir for human visceral leishmaniasis and many of the clinical and pathologic signs observed in dogs are similar to the pattern of the disease in humans. The skin is the first point of contact with Leishmania and was considered to be an important reservoir compartment for parasites in healthy and sick infected dogs and the important role of dogs in VL transmission is supported by the high parasite loads found in the skin of infected animals. Thus, the aim of this work was study the extracellular matrix alterations in the ear skin of dogs naturally infected with Leishmania Leishmania infantum.

Eight non-infected dogs were used as control group. During necropsy, ear skin fragments were collected and fixed in formaldehyde solution. All animals showed an inflammatory reaction ranging from mild to intense, and the cellular exudate consisting mainly of mononuclear cells. The inflammation was higher in symptomatic dogs when compared to the other groups. In the analysis of collagen area, it was observed that the more intense the inflammation, like the presented by the symptomatic dogs, the lower area of collagen was noticed. In the Picrossirius red analysis, a reduction of collagen type 1 fibers was observed in symptomatic animals when compared to control group.

There was also an increase in type III collagen fibers in oligosymptomatic dogs compared to control dogs. Since this compartment is formed mainly by collagen fibers, it can be assumed that the presence of amastigotes may be involved in the degradation of the extracellular matrix. These data suggest that there was injury in the skin of oligosymptomatic animals but they managed to repair this damage. However, the symptomatic animals were injured but they could not overcome the injury, perhaps because the higher inflammatory process observed in these animals. In this sense, the skin should be considered as a good place for parasitological analysis, being a reliable indicator for the severity of clinical disease in the CVL.

Infected dogs play an important role in public health as sentinels for American cutaneous leishmaniasis ACL agents on the environment allowing to evaluate the spread of this disease. The town was divided in five urban regions used for strategic popular health programs and residences, from 42 blocks selected randomly, were visited from July to November in Blood samples of dogs were taken.
