This work describes natural infection by Leishmania in a domestic cat where amastigote forms of the parasite were observed in the popliteal lymph node imprint. Positive and negative serological reactions were observed by enzyme-linked immunosorbent assay (ELISA) and indirect immunofluorescence assay (IFA), respectively. Polymerase chain reaction (PCR) revealed that the nucleotide sequence of the sample was identical to Leishmania (L.) chagasi. This is the first report of the disease in felines of the city of Andradina, SP, an area considered endemic for canine and human visceral leishmaniasis.
