Background: Canine visceral leishmaniasis is a worldwide zoonosis, with dogs being the main urban reservoirs. It is caused by a protozoan of the genus Leishmania spp. and is transmitted to mammals through a vector belonging to the phlebotomines family. Its treatment aims to reduce the parasitic load preventing these animals from being transmitters. Immunotherapy has been shown to be efficient in stimulating the patients immune response, improving the general condition and preventing recurrence. This report describes the case of a dog diagnosed with canine visceral leishmaniasis submitted to immunotherapy and drug protocol, noting significant general improvement. Case: An 8-year-old female dog was treated with ulcerated lesions on the paw pads, nasal plane and lip region, onychogryphosis and ungeitis, in addition, hypertrophied popliteal lymph nodes and erosive lesions in the elbows, without improvement with previous treatments. Serological examination was then performed to diagnose leishmaniasis by the immunosorbent assay (ELISA) technique with negative results. In addition, was performed puncture of the popliteal lymph node, sample in which amastigote forms of Leishmania were observed and blood sample analysis by immunochromatographic rapid test showing reagent result, confirming the diagnosis of canine visceral leishmaniasis. The treatment protocol with marbofloxacin, allopurinol, prednisolone and domperidone was initiated. Thirty days later, there was a total improvement of the lesions and healing of the paw pads. Immunotherapy was then initiated by applying three double doses of recombinant vaccine against canine visceral leishmaniasis. The applications were made subcutaneously, with an interval of 21 days between them, still maintaining allopurinol. After six months a...(AU)
