赫氏利什曼原虫，新种描述了从来自哥斯达黎加的二趾树懒（Choloepus hoffmanni）和三趾树懒（Bradypus griseus）的血液、内脏和皮肤中分离纯培养物。此外，它还从以下白蛉中分离到：Trapidoi，L.和L. shannoni。在最终宿主中未观察到无鞭毛体形式，但在33 ℃的组织培养中获得了无鞭毛体形式。前鞭毛体和无鞭毛体均不能感染仓鼠。这种新的寄生虫经常在培养物中分离出来，与其他血鞭毛虫如L。和兰氏锥虫（Trypanosoma rangeli）。
Leishmania herreri sp. n. is described after isolation in pure culture from blood, viscera and skin of two-toed (Choloepus hoffmanni) and three-toed (Bradypus griseus) sloths from Costa Rica. Also, it was isolated from the following sandflies: Lutzomyia trapidoi, L. ylephiletor and L. shannoni. The amastigote forms were not seen in the final hosts but they were obtained in tissue culture at 33 C. Both promastigotes and amastigotes failed to infect hamsters. The new parasite is isolated frequently in culture, mixed with other hemoflagellates such as L. braziliensis, Endotrypanum sp. and Trypanosoma rangeli.
