Ocorrência de leishmaniose em gatos de área endêmica para leishmaniose visceral

Despite the description of several cases of feline leishmaniasis around the world, little information is available about the importance of the cat as a reservoir of the disease. The aim of the present study was to determine the occurrence of leishmaniasis in cats from an endemic area for visceral leishmaniasis in Brazil. Two hundred cats were included in this study. Infection was evaluated through the presence of amastigotes in stained smears from fine-needle aspirates of lymph nodes, bone marrow, spleen and liver, and by antibody reactivity against Leishmania chagasi using indirect ELISA. Our results showed a prevalence of infection in 14.5% (31/200) of the feline population studied, with 4% (8/200) of positivity by parasitological diagnosis and 11.5% (23/200) by serology.
