RESUMEN

Leishmaniasis is an anthropozoonosis transmitted by vectors, with dogs being the main domestic reservoirs. Brazil is one of the countries most affected by this disease, and it has been described in humans and dogs in every region in the country. In the northern region leishmaniasis cases in humans have been described in more than 100 municipalities in the State, including the capital, Belém. This study involves two cases of canine visceral leishmaniasis in which the animals developed clinical signs compatible with the disease in urban areas in Belém, the Pará state capital. The diagnosis was confirmed via polymerase chain reaction (PCR) to detect SSUr-rDNA and kDNA of Leishmania sp. and Leishmania infantum, respectively. In one of the cases the animal died and in the other the animal underwent treatment with medicines prescribed for dogs. Through this treatment, parasitemia in the second animal has been kept under control and is being monitored through molecular tests. Previously, no canine cases had been notified from urban neighborhoods in the city of Belém, but only on the island of Cotijuba, at a distance of 29 kilometers from the city. Cases of canine and human leishmaniasis have been recorded close to the capital, Belém, which has areas of conserved vegetation and where the presence of disease vectors has been described. Thus, as has been done in several other Brazilian cities, this study uses clinical and laboratory findings to confirm the presence of autochthonous cases of canine visceral leishmaniasis in the city of Belém.

A leishmaniose é uma antropozoonose transmitida por vetores, sendo os cães os principais reservatórios domésticos. O Brasil é um dos países mais acometidos por esta doença, sendo descrita em humanos e cães em todas as regiões do país. Na região norte casos de leishmaniose em humanos foram descritos em mais de 100 municípios do Estado, incluindo a capital, Belém. Este estudo envolve dois casos de leishmaniose visceral canina em que os animais desenvolveram sinais clínicos compatíveis com a doença em áreas urbanas de Belém, capital do estado do Pará. O diagnóstico foi confirmado pela reação em cadeia da polimerase (PCR) para detectar o SSUr-rDNA e kDNA de Leishmania sp e Leishmania infantum, respectivamente. Em um dos casos o animal veio a óbito e no outro o animal foi submetido a tratamento com medicamentos prescritos para cães. Por meio desse tratamento, a parasitemia no segundo animal foi mantida sob controle e está sendo monitorada por meio de testes moleculares. Anteriormente, nenhum caso canino havia sido notificado em bairros urbanos da cidade de Belém, apenas na ilha de Cotijuba, distante 29 quilômetros da cidade. Casos de leishmaniose canina e humana foram registrados próximo à capital, Belém, que possui áreas de vegetação conservada e onde foi descrita a presença de vetores de doenças. Assim, como tem sido registrado em várias outras cidades brasileiras, este estudo utiliza achados clínicos e laboratoriais para confirmar a presença de casos autóctones de leishmaniose visceral canina na cidade de Belém.
