A serological and molecular investigation of American cutaneous leishmaniasis in dogs, three years after an outbreak in the Northwest of Paraná State, Brazil.

Classic and molecular (polymerase chain reaction--PCR) techniques were used to diagnose American cutaneous leishmaniasis in 149 dogs from an area in the northwest of Paraná State, Brazil, where an American cutaneous leishmaniasis outbreak occurred in 2002. The results were compared to a set of previously obtained results. Twenty-five dogs had positive indirect immunofluorescence (IIF) (titers > or = 40), including two animals with suggestive lesions.

This study aimed to verify the occurrence of the canine disease in ACL endemic areas. From September 1999 to July 2002, dogs were investigated in 7 rural areas of 5 municipalities where autochthonous human cases of ACL had been reported.
