Total numbers and distribution of genera, subgenera and species were determined for the ciliate protozoa in rumen contents of 4 Brazilian water buffalo Bubalus bubalis Linnaeus. The fauna of one animal, housed in close proximity to European and zebu-type cattle, differed considerably from that of the remaining animals, which were somewhat isolated on a large ranch. Several of the protozoan species observed in the semi-isolated animals were first described in rumen contents from humped Indian cattle, and their subsequent occurrence in other hosts and geographic locations has been limited or absent. In all, 49 different species of protozoa were found, 8 of which have not been previously described. Three of the new species belong to the genus Entodinium: E. ciculum sp. n., E. spinonucleatum sp. n. and E. triangulum sp. n.; 4 to Diplodinium (Ostracodinium): D. (O.) brazili sp. n., D. (O.) esalqum sp. n., D. (O.) nucleolobum sp. n., and D. (O.) tiete sp. n.; and one to Diplodinium (Eudiplodinium): D. (E.) bubalus sp. n.
测定了4头巴西水牛（Bubalus bubalis Linnaeus）瘤胃内容物中纤毛虫原生动物的属、亚属和物种的总数及分布情况。其中一头与欧洲牛和瘤牛型牛圈养在一起的动物的动物区系，与其余在大牧场中相对隔离的动物的动物区系有很大差异。在半隔离动物中观察到的几种原生动物物种最初是在驼背印度牛的瘤胃内容物中描述的，它们随后在其他宿主和地理位置的出现情况有限或不存在。总共发现了49种不同的原生动物物种，其中8种以前未曾描述过。3个新物种属于内毛虫属（Entodinium）：环内毛虫（E. ciculum sp. n.）、棘核内毛虫（E. spinonucleatum sp. n.）和三角内毛虫（E. triangulum sp. n.）；4个属于双毛虫属（Ostracodinium亚属）：巴西双毛虫（D. (O.) brazili sp. n.）、埃萨尔库姆双毛虫（D. (O.) esalqum sp. n.）、核叶双毛虫（D. (O.) nucleolobum sp. n.）和铁特双毛虫（D. (O.) tiete sp. n.）；1个属于双毛虫属（Eudiplodinium亚属）：水牛双毛虫（D. (E.) bubalus sp. n.）。
