Abstract

A small piroplasm was detected in blood smears from lions (Panthera leo) in the Kruger National Park (KNP; Republic of South Africa) during 1991/1992. The parasite was identified provisionally as Babesia felis, but sera from these lions tested negative to B. felis antigen in the indirect immunofluorescent antibody test (IFAT). Blood from an infected lion was subsequently subinoculated into a domestic cat and two leopards in an attempt to identify the parasite. A lion also was infected with B. felis (from a cat). Serum samples collected from these animals were tested against B. felis, the KNP small piroplasm, and Cytauxzoon felis antigen in the IFAT. The serological results indicate that the KNP small piroplasm isolated from the lion is probably a distinct species from B. felis and C. felis.

摘要

1991年至1992年期间，在南非共和国克鲁格国家公园（KNP）的狮子（Panthera leo）血涂片上检测到一种小型梨浆虫。该寄生虫初步鉴定为猫巴贝斯虫，但这些狮子的血清在间接免疫荧光抗体试验（IFAT）中对猫巴贝斯虫抗原呈阴性反应。随后，将一只感染狮子的血液接种到家猫和两只豹体内，试图鉴定该寄生虫。一只狮子也感染了来自猫的猫巴贝斯虫。从这些动物身上采集的血清样本在IFAT中针对猫巴贝斯虫、KNP小型梨浆虫和猫细胞内原虫抗原进行了检测。血清学结果表明，从狮子身上分离出的KNP小型梨浆虫可能是一种与猫巴贝斯虫和猫细胞内原虫不同的物种。
