Abstract

Eight out of 47 Bradypus griseus and 14 out of 18 Choloepus hoffmanni yielded positive cultures for flagellates from blood, skin, liver or spleen. In some cases, more than one species of flagellate was isolated from one animal or site. Although amastigotes were obtained in tissue cultures from several isolates containing different types of promastigotes, only four of these strains (two from each species of host) were infective for hamsters and considered as Leishmania braziliensis. Infection with one of the strains was possible only after it has been passed through tissue culture.

摘要

47只灰树懒中有8只，18只霍氏树懒中有14只，其血液、皮肤、肝脏或脾脏的鞭毛虫培养呈阳性。在某些情况下，从一只动物或一个部位分离出不止一种鞭毛虫。尽管从含有不同类型前鞭毛体的几种分离物的组织培养物中获得了无鞭毛体，但这些菌株中只有4株（每种宿主各2株）对仓鼠具有感染性，并被认为是巴西利什曼原虫。只有在通过组织培养传代后，其中一种菌株才有可能感染。
