A malacological survey to detect foci of transmission of schistosomiasis and other parasitic diseases was undertaken into water-courses from 13 municipalities of microregion of Belo Horizonte, MG, Brazil. From 1990 to 1996, 22,066 snails were collected. From those, 378 (1.7%) were found infected by trematodes: Biomphalaria glabrata (7,920), infected by Schistosoma mansoni (1.9%), Echinostomatidae (1.2%), Strigeidae (0.6%), Cercaria minense (0.1%) and Derogenidae (-0.1%); B. straminea (4,093) infected by Strigeidae (0.6%), Echinostomatidae (0.2%), Clinostomatidae (-0.1%) and two unidentified cercariae; B. tenagophila (1,338), infected by Strigeidae (0.1%) and Physa marmorata (1,776) by Echinostomatidae (1.6%). The snails Biomphalaria peregrina, B. occidentalis, B. schrammi, Drepanotrema depressissimum, D. lucidum, D. cimex, Physa cubensis, Lymnaea columella, Melania tuberculata, Idiopyrgus souleyetianus, Pomacea sp, Anodontites sp and Ancylidae were found noninfected. Snails from 9 municipalities were infected by S. mansoni and from 11 by other trematodes.
在巴西米纳斯吉拉斯州贝洛奥里藏特市微型区域的13个市的水道中进行了一项贝类学调查，以检测血吸虫病和其他寄生虫病的传播源。1990年至1996年期间，共采集了22,066只蜗牛。其中，378只（1.7%）被吸虫感染：光滑双脐螺（7,920只），感染曼氏血吸虫的比例为1.9%，感染棘口科吸虫的比例为1.2%，感染斜睾科吸虫的比例为0.6%，感染微小尾蚴的比例为0.1%，感染卷棘口吸虫科吸虫的比例为-0.1%；稻草双脐螺（4,093只），感染斜睾科吸虫的比例为0.6%，感染棘口科吸虫的比例为0.2%，感染 Clinostomatidae科吸虫的比例为-0.1%，还有两种未鉴定的尾蚴；嗜气管双脐螺（1,338只），感染斜睾科吸虫的比例为0.1%，而大理石膀胱螺（1,776只）感染棘口科吸虫的比例为1.6%。发现奇异双脐螺、西方双脐螺、施氏双脐螺、压低双脐螺、透明双脐螺、吸血双脐螺、古巴膀胱螺、柱形椎实螺、结节美拉尼亚螺、苏氏艾氏螺、瓶螺属、无齿蚌属、环棱螺科未被感染。来自9个市的蜗牛感染了曼氏血吸虫，来自11个市的蜗牛感染了其他吸虫。
