to describe the geographical distribution of intermediate hosts of Schistosoma mansoni in five Brazilian states.
this was a descriptive cross-sectional study; municipalities were selected in the states of Paraná (78), Minas Gerais (120), Bahia (82), Pernambuco (51) , and Rio Grande do Norte (98), for the period 2012 to 2014; these municipalities were chosen because they did not have current records of the presence of snails vectores de S. mansoni. The molluscs were captured and taxonomically identified and examined for S. mansoni cercariae.
the work was carried out in 427 municipalities (99.5% of the 429 selected); the presence of mollusks was registered in 300 (70.2%) municipalities; Biomphalaria glabrata were found in 62 (21%) municipalities, B. straminea in 181 (60%), B. tenagophila in three (1%); B. glabrata/B. straminea association was found in 53 municipalities (18%) and B. glabrata/B. tenagophila association in one (0.3%) municipality.
B. glabrata, B. straminea and B. tenagophila distribution records obtained in this study are consistent with previously known distribution.
描述曼氏血吸虫中间宿主在巴西五个州的地理分布。
这是一项描述性横断面研究；在2012年至2014年期间，从巴拉那州（78个）、米纳斯吉拉斯州（120个）、巴伊亚州（82个）、伯南布哥州（51个）和北里奥格兰德州（98个）选择了一些城市；选择这些城市是因为它们目前没有曼氏血吸虫中间宿主蜗牛的存在记录。捕获软体动物并进行分类鉴定，检查是否有曼氏血吸虫尾蚴。
研究在427个城市开展（占所选429个城市的99.5%）；在300个（70.2%）城市记录到软体动物的存在；在62个（21%）城市发现光滑双脐螺，在181个（60%）城市发现稻草双脐螺，在3个（1%）城市发现嗜眼双脐螺；在53个（18%）城市发现光滑双脐螺/稻草双脐螺组合，在1个（0.3%）城市发现光滑双脐螺/嗜眼双脐螺组合。
本研究获得的光滑双脐螺、稻草双脐螺和嗜眼双脐螺分布记录与先前已知分布一致。
