BACKGROUND Visceral Leishmaniasis (VL) is a neglected tropical disease that afflicts some of the poorest populations in the world including people living in the Bihar state of India. Due to efforts from local governments, NGOs and international organizations, the number of VL cases has declined in recent years. Despite this progress, the reservoir for transmission remains to be clearly defined ...

We report a case of exclusive involvement of lymph node in leishmaniasis presenting as generalized lymphadenopathy. The diagnosis of lymphatic leishmaniasis was confirmed by the presence of Leishmania donovani body in fine needle aspiration cytology, positive direct agglutination test and anti-rK39 antibodies. The bone marrow aspiration was negative for Leishmania donovani body. This is the fir...

Accurate diagnosis of canine leishmaniasis (CanL) is essential toward a more efficient control of this zoonosis, but it remains problematic due to the high incidence of asymptomatic infections. In this study, we present data on the development of enzyme-linked immunosorbent assay (ELISA)-based techniques for the detection of antibodies against the recombinant protein Leishmania infantum cytosol...

BACKGROUND One of the most important drawbacks in visceral leishmaniasis (VL) population studies is the difficulty of diagnosing asymptomatic carriers. The aim of this study, conducted in an urban area in the Southeast of Brazil, was to evaluate the performance of serology to identify asymptomatic VL infection in participants selected from a cohort with a two-year follow-up period. METHODOLOG...

BACKGROUND The diagnosis of visceral leishmaniasis (VL) in patients with fever and a large spleen relies on showing Leishmania parasites in tissue samples and on serological tests. Parasitological techniques are invasive, require sophisticated laboratories, consume time, or lack accuracy. Recently, rapid diagnostic tests that are easy to perform have become available. OBJECTIVES To determine ...

An rK39 immunochromatographic test and immunofluorescent-antibody test (IFAT) for serodiagnosis of canine leishmaniasis were evaluated. The two tests showed correlation for all but one of the sera obtained from 68 dogs confirmed as leishmaniasis cases and 40 dogs (22 healthy dogs and 18 dogs with other diseases) from areas where the disease is not endemic. Specificity was 100% for both tests, w...

Dogs are considered the main reservoir of Leishmania infantum. This protozoan causes visceral leishmaniasis (VL), an uncontrolled urban zoonosis in Brazil. Serological tests and polymerase chain reaction (PCR) on peripheral blood were performed to identify infected dogs in scenarios of higher and lower prevalence of the disease (Teresina and Vitória). One-hundred infected and 57 non-infected an...
