[Human and canine American cutaneous leishmaniasis in Mariluz, Paraná State, Brazil].
An outbreak of American cutaneous leishmaniasis was reported in 2002 in Mariluz, northwestern Paraná State, Brazil. Of 38 humans who were investigated, four had healed lesions, ten showed lesions in the healing process, and 24 had active lesions. Of the 126 dogs, 20 (15.9%) presented suggestive lesions and 24 (19%) had positive serology. Parasites isolated from two patients and three dogs were identified as Leishmania (Viannia) braziliensis serodeme I. The captured sand flies were identified as Nyssomyia whitmani, N. neivai, and Migonemyia migonei. Considering that the region where the cases occurred is similar to other old human settlements in Paraná State, the environmental alterations and remaining forests facilitate the maintenance of the parasite's enzootic cycle and transmission to humans and domestic animals, thereby maintaining the endemicity of American cutaneous leishmaniasis.
