[A canine survey in a recent focus of cutaneous leishmaniasis in the city of Sabará, the metropolitan area of Belo Horizonte].
In 1992, a dog naturally infected with Leishmania was found in a periurban area of Sabará, state of Minas Gerais, where human cutaneous leishmaniasis had been previously described. The parasite was classified as Leishmania, subgenus Viannia, which L. braziliensis, the main species of parasite present in the southeast Brazil, also belongs. In order to assess the importance of the dog in the transmission cycle of the disease, a canine survey was undertaken. Six hundred thirty-one dogs were examined and the prevalence of seropositive dogs for crude Leishmania amazonensis antigen was 3.2%. The presence of infected people and seropositive dogs either near or in the same house was observed. This fact suggests some transmission in the domiciliary environment, with the dogs being a risk factor for human infection in that periurban area. In the other hand, the low percentage of seropositive dogs points towards a secondary importance of these animals in the transmission of Leishmaniasis in that recent focus of the disease.
