Visceral leishmaniasis (VL) is expanding in the Brazilian territory. Dogs are considered an important urban reservoir; however, studies have demonstrated the presence of infected cats in some Brazilian states. This report aimed to describe a case of Leishmania (Leishmania) infantum infection in a two-month-old domestic feline from a Brazilian region with a high incidence of human visceral leishmaniasis. The analyzed samples were the cat’s blood, conjunctiva, spleen, liver, popliteal, submandibular and mesenteric lymph nodes, skin, lung and kidney. The diagnostic methods were: parasitological examination, polymerase chain reaction (PCR) and an immunoflurescence antibody test (IFAT). All tissues were positive. The title obtained using the IFAT was 1:160. The animal was negative for feline immunodeficiency virus (FIV) and feline leukemia virus (FeLV). This work addresses the first case of feline leishmaniasis in the state of Tocantins, and reveals data that may contribute to the knowledge of the disease, since it has been shown to be able to develop rapidly and fatally in kittens, with the ability to infect several tissues.
