Published and unpublished observations on geographical distribution of Biomphalaria snails in the State of Minas Gerais, Brazil, were compiled. This work is aimed at knowing the present occurrence of Biomphalaria species in this region, and at contributing to the elaboration of the planorbid chart of Minas Gerais. In malacological surveys, performed by several researchers, the presence of seven species of this genus was recorded. Those planorbids were found in 12 mesoregions, in 283 (33.1%) municipalities out of 853 with the following distribution: B. glabrata (185 municipalities), B. straminea (125), B. tenagophila (58), B. peregrina (57), B. schrammi (26), B. intermedia (20) and B. occidentalis (2). B. glabrata and B. tenagophila are found naturally infected by Schistosoma mansoni in Minas Gerais. In 24 municipalities the three snail hosts of S. mansoni in Brazil, B. glabrata, B. tenagophila and B. straminea, are present.
整理了巴西米纳斯吉拉斯州关于双脐螺地理分布的已发表和未发表的观察资料。这项工作旨在了解该地区双脐螺物种的当前分布情况，并为编制米纳斯吉拉斯州扁卷螺图表做出贡献。在几位研究人员进行的贝类学调查中，记录到该属的7个物种。这些扁卷螺在12个中区域、853个市中的283个（33.1%）被发现，分布如下：光滑双脐螺（185个市）、淡黄双脐螺（125个）、嗜气管双脐螺（58个）、奇异双脐螺（57个）、施氏双脐螺（26个）、中间双脐螺（20个）和西方双脐螺（2个）。在米纳斯吉拉斯州，光滑双脐螺和嗜气管双脐螺自然感染曼氏血吸虫。在24个市中，巴西曼氏血吸虫的三种螺类宿主，即光滑双脐螺、嗜气管双脐螺和淡黄双脐螺都有分布。
