During 2001 and 2002, blood smears from 37 of 120 fishes belonging to 10 species captured in the Okavango Delta region of Botswana, were found to harbour trypanosomes. These trypanosomes displayed differing staining properties, were morphometrically variable, and ranged in total length from 29.5 to 80.8 microm. Mixed populations of the smaller and larger trypanosomes were found in most fish examined. Despite variations in size and appearance, these specimens are tentatively identified as Trypanosoma mukasai Hoare, 1932, likely adding another 9 new hosts to those known for this parasite. It is possible that Trypanosoma clariense Pienaar, 1962, described from Clarias gariepinus in South Africa, is also a junior synonym of T. mukasai.
2001年至2002年期间，在博茨瓦纳奥卡万戈三角洲地区捕获的属于10个物种的120条鱼中，有37条的血涂片被发现含有锥虫。这些锥虫表现出不同的染色特性，形态测量结果可变，全长范围为29.5至80.8微米。在大多数检查的鱼中发现了较小和较大锥虫的混合种群。尽管大小和外观存在差异，但这些标本暂被鉴定为1932年的穆卡萨伊锥虫（Trypanosoma mukasai Hoare），这可能为此寄生虫已知的宿主又增加了9个新宿主。1962年从南非的加里波非鲫（Clarias gariepinus）描述的克拉里锥虫（Trypanosoma clariense Pienaar）也有可能是穆卡萨伊锥虫的次异名。
