The parasite that causes simian malaria in the Brazilian Amazon, Plasmodium brasilianum, is infective to man. In this region, where humans live within and in close proximity to the forest, it was suspected that this parasite could be the cause of a zoonosis. A study was performed in the areas surrounding two hydroelectric plants in the Amazon, Balbina and Samuel, aiming at determining the zoonotic potential of this parasite. P. brasilianum was detected in, respectively, 15.8% and 9.9% of 126 and 252 primates belonging to seven and eight species examined from Balbina and Samuel. The highest malaria infection rates were found among the red-howler monkey Alouatta seniculus straminea (32.3%), the bearded-saki Chiropotes satanas chiropotes (50%) and the spider-monkey Ateles paniscus paniscus (2[1+]) from Balbina and in the squirrel-monkey Saimiri ustus (21%) and the black-faced-spider-monkey Ateles paniscus chamek (28.6%) from Samuel.
在巴西亚马逊地区引发猴疟疾的寄生虫——巴西疟原虫，可感染人类。在该地区，人类生活在森林内部及周边，因此怀疑这种寄生虫可能是一种人畜共患病的病因。在亚马逊地区的两个水电站——巴尔比纳水电站和塞缪尔水电站周边地区开展了一项研究，旨在确定这种寄生虫的人畜共患病传播潜力。在从巴尔比纳和塞缪尔检查的分别属于7个和8个物种的126只和252只灵长类动物中，巴西疟原虫的检出率分别为15.8%和9.9%。疟疾感染率最高的是来自巴尔比纳的红吼猴阿拉奥特亚小僧帽猴（32.3%）、僧面猴黑僧面猴（50%）和蛛猴巴拿马蛛猴（2[1+]），以及来自塞缪尔的松鼠猴乌氏松鼠猴（21%）和黑面蛛猴巴拿马蛛猴亚种（28.6%）。
