[Epidemiological aspects of canine American tegumentary leishmaniasis in the Municipality of Paraty, State of Rio de Janeiro, brazil]. / Aspectos epidemiológicos da leishmaniose tegumentar americana em cães, no Município de Paraty, Estado do Rio de Janeiro, Brasil.

American tegumentary leishmaniasis (ATL) is endemic in the State of Rio de Janeiro, with the highest incidence observed in the municipalities along the Southern coast. A total of 169 human cases were reported from 1993 to 1995 in the municipality of Paraty, representing 15% of all case reports in the State of Rio de Janeiro during that period. From March to December, 1996, a survey was conducted in endemic american tegumentary leishmaniasis (ATL) areas (Praia Grande, Taquari, Várzea do Machado, and Graúna) in Paraty. 326 households with 215 pet dogs were surveyed. The initial study consisted of taking venous blood samples to perform RIFI and ELISA tests. The canine skin test was performed during the same visit and was positive in 8.8% of dogs. Of the 215 dogs, 5 presented lesions suspected of ATL; biopsies and the vacuum aspiration technique were performed on these cases. Correlating the study areas with the results obtained, some dogs presented sub-clinical infection, highly relevant to studies on canine ATL infection in the State of Rio de Janeiro.
