The presence of American cutaneous leishmaniasis (ACL) in the communities of the Campus FIOCRUZ Mata Atlântica (CFMA) in the City of Rio de Janeiro initiated the investigation of the Phlebotominae fauna in the Atlantic Forest to determine the occurrence of putative ACL vectors associated with the enzootic cycle.
For 24 consecutive months, sand flies were captured inside the forest and in the border area near the communities.
The following sand fly species were identified: Brumptomyia brumpti, Brumptomyia cunhai, Brumptomyia nitzulescui, Lutzomyia edwardsi, Lutzomyia pelloni, and Lutzomyia quinquefer. Other identified sand fly vectors, such as Lutzomyia intermedia (the predominant species), Lutzomyia migonei, Lutzomyia whitmani, Lutzomyia fischeri, and Lutzomyia hirsuta hirsuta, are associated with ACL transmission, and the vector for American visceral leishmaniases (AVL), Lutzomyia longipalpis, was also found.
All sand fly vectors were found in both studied environments except for Lutzomyia whitmani, which was only identified in the forest. This study represents the first identification of Lutzomyia longipalpis in the CFMA, and the epidemiological implications are discussed.
里约热内卢市校园菲奥克鲁兹大西洋森林(CFMA)社区中存在美洲皮肤利什曼病(ACL),这引发了对大西洋森林中白蛉亚科动物群的调查,以确定与动物疫病流行周期相关的假定ACL传播媒介的存在情况。
连续24个月在森林内部和社区附近的边境地区捕获白蛉。
鉴定出以下白蛉种类:布鲁姆普托米亚·布鲁姆普蒂、布鲁姆普托米亚·库海、布鲁姆普托米亚·尼祖列斯库伊、爱德华兹白蛉、佩洛尼白蛉和五刺白蛉。其他已鉴定的白蛉传播媒介,如中间白蛉(优势种)、米氏白蛉、惠特曼白蛉、费氏白蛉和多毛白蛉,与ACL传播有关,并且还发现了美洲内脏利什曼病(AVL)的传播媒介长须白蛉。
除惠特曼白蛉仅在森林中被鉴定出外,所有白蛉传播媒介在两个研究环境中均被发现。本研究首次在CFMA中鉴定出长须白蛉,并对其流行病学意义进行了讨论。
