Trypanosoma (Herpetosoma) leeuwenhoeki, originally described in Panamanian sloths, was isolated from Didelphis marsupialis (Marsupialia) and Choloepus hoffmanni (Edentata) inhabiting the Pacific coast of Colombia. Trypanosomes were characterized by their large blood forms (total length 51-53 microns), poor infectivity for mice, and lack of development in Rhodnius prolixus. Isoenzyme studies, with either strains or clones, revealed homogeneous profiles clearly distinct from Trypanosoma cruzi and Trypanosoma rangeli reference strains. The present report extends the geographical distribution of T. leeuwenhoeki to South America and broadens its known host range to another order of mammals.
利文霍克锥虫（赫佩托锥虫属）最初是在巴拿马树懒身上发现的，此次是从栖息于哥伦比亚太平洋沿岸的南美袋鼬（有袋目）和霍氏树懒（贫齿目）中分离出来的。该锥虫的特征为其大型血液形态（全长51 - 53微米）、对小鼠感染力低以及在长红猎蝽体内无法发育。对菌株或克隆进行的同工酶研究显示，其图谱均一，明显不同于克氏锥虫和兰氏锥虫的参考菌株。本报告将利文霍克锥虫的地理分布扩展至南美洲，并将其已知宿主范围扩大到另一目哺乳动物。
