Abstract

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.

摘要

赫氏利什曼原虫新种（Leishmania herreri sp. n.）是在从哥斯达黎加的二趾树懒（霍氏树懒Choloepus hoffmanni）和三趾树懒（灰树懒Bradypus griseus）的血液、内脏和皮肤中分离出纯培养物后描述的。此外，它还从以下白蛉中分离得到：特拉氏白蛉（Lutzomyia trapidoi）、耶氏白蛉（L. ylephiletor）和香氏白蛉（L. shannoni）。在终末宿主体内未见到无鞭毛体，但在33℃的组织培养中获得了无鞭毛体。前鞭毛体和无鞭毛体均未能感染仓鼠。这种新寄生虫在培养物中经常与其他血鞭毛虫如巴西利什曼原虫、内锥虫属（Endotrypanum sp.）和兰氏锥虫（Trypanosoma rangeli）混合分离得到。
