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.
2002年,巴西巴拉那州西北部的玛丽卢兹报告了一起美洲皮肤利什曼病疫情。在接受调查的38人中,4人有愈合的病灶,10人病灶处于愈合过程中,24人有活动性病灶。在126只狗中,20只(15.9%)有疑似病灶,24只(19%)血清学检测呈阳性。从两名患者和三只狗身上分离出的寄生虫被鉴定为巴西利什曼原虫(维安尼亚利什曼原虫)血清型I。捕获的白蛉被鉴定为惠氏白蛉、内氏白蛉和米氏米蛉。鉴于病例发生地区与巴拉那州其他古老人类定居点相似,环境变化和留存的森林有利于寄生虫动物疫源地循环的维持以及向人类和家畜的传播,从而维持美洲皮肤利什曼病的地方性流行。
