The diagnosis of visceral leishmaniasis involves isolation of the parasites in culture or invasive and risky techniques including demonstration of parasite in stained preparations of relevant tissues such as spleen, bone marrow or lymph node by light microscopic examination remains a gold standard. Serological tests using rK39 in ELISA or rapid immunochromatographic tests, direct agglutination ...
Several serology-based immunoassays are used to diagnose visceral leishmaniasis (VL), a chronic protozoan parasitic disease caused by the Leishmania donovani complex. These tests are primarily designed to diagnose the most severe clinical form of VL, known as kala-azar. However, leishmanial infection is frequently asymptomatic and may manifest only as a positive serologic response or positive l...
Visceral leishmaniasis (VL) is a form of leishmaniasis, which is caused by infection with the protozoan parasite Leishmania, and is often fatal unless it is treated. Rapid and accurate diagnosis of VL is important for effective treatment. Here we report the cloning of previously undescribed tandem repeat (TR) proteins of Leishmania infantum and an evaluation of VL patient antibody responses to ...
Objective Characterize the foci of visceral leishmaniasis infection in Neiva with a clinical and epidemiological approach. Materials and Methods Six children consulted medical services with hepatosplenomegaly. They were found to have anemia and leukopenia. The diagnosis was performed by bone marrow (five patients) and spleen (1 patient) aspiration. An active search for cases was carried out in ...
INTRODUCTION The present study was designed to assess the occurrence of co-infection or cross-reaction in the serological techniques used for detecting the anti-Leishmania spp., -Babesia canis vogeli and -Ehrlichia canis antibodies in urban dogs from an area endemic to these parasites. METHODS The serum samples from dogs were tested for the Babesia canis vogeli strain Belo Horizonte antigen a...
HIV/AIDS-associated visceral leishmaniasis may display the characteristics of an aggressive disease or without specific symptoms at all, thus making diagnosis difficult. The present study describes the results of diagnostic tests applied to a series of suspected VL cases in HIV-infected/AIDS patients admitted in referral hospitals in Pernambuco, Brazil. From a total of 14 eligible patients with...
Abstract Background The Benishangul-Gumuz region is an important development corridor in Ethiopia. Large-scale projects such as the Great Renaissance Dam, mining and agriculture have entailed huge environmental modifications settlement pattern changes. There no detailed epidemiological information on visceral leishmaniasis (VL) region. Materials methods A cross-sectional study was carried out t...
Quantitative computerized Western blot analysis of antibody responses during experimental canine Leishmania infantum infection distinguished between immunodominant and nonimmunodominant protein bands. Six infected beagles, positive by both PCR and parasite culture, were monitored over 75 weeks postinfection and during a 12-week allopurinol treatment course. All dogs were symptomatic at the time...
