Abstract
In domestic cats, the number of infections caused by parasites of the genus Leishmania is becoming increasingly significant, although the role of felines in this cycle is not yet clear. The aim of this study was to observe the prevalence of anti- Leishmania spp. using different antigens: Leishmania Viannia brasiliensis , Leishmania Leishmania amazonensis and Leishmania Leishmania infantum , in serological samples from domestic cats, from castration efforts carried out in the city of Londrina / PR, from 2015 to 2016. The test was used in indirect ELISA (Enzyme-Linked Immunosorbent Assay) serological diagnosis, with the aforementioned antigens for plaque sensitization. Of the total of 199 samples analyzed, 69 (34.67%) were considered reagents for Leishmania spp., 37 samples (18.59%) were considered reagents for L. (L.) amazonensis ; 40 samples (20.10%) for L. (V.) brasiliensis and 24 (12.06%) for L. (L.) infantum . In 42 samples (21.10%) reactivity to ELISA was observed in more than one of the antigens used. A higher prevalence of antibodies was observed when using the L. (V.) brasiliensis antigen, confirming that this is the most reported species in the state of Parana. We can conclude that antibodies against Leishmania spp. are circulating in the studied feline population; in addition, the use of the Leishmania antigen species most prevalent in the study region is indicated for obtaining more reliable results.
