Cystoisospora felis (Wenyon 1923) was identified in a 3-month-old, captive jaguar (Panthera onca) presenting with signs of gastrointestinal distress. The cub was fed beef, chicken, and commercial diet. Examination of fresh feces detected large (47.8 μm × 35 μm) unsporulated oocysts. Sporulated oocysts contained 2 sporocysts, each with 4 sporozoites. Oocyst morphometrics agreed with published features of C. felis described from domestic felines. Partial mitochondrial cytochrome c oxidase subunit I (mtCOI) gene was PCR-amplified and sequenced; the resulting sequence showed 100% identity to a C. felis isolate from a domestic cat. This is the first molecularly confirmed report of C. felis infecting and producing clinically evident, enteric disease in a jaguar cub.
猫贝蛔虫（Wenyon 1923）被鉴定为一只 3 个月大的圈养美洲虎（Panthera onca）出现胃肠道不适症状的病原体。这只幼虎喂食牛肉、鸡肉和商业饲料。对新鲜粪便的检查发现了大的（47.8μm×35μm）未孢子化卵囊。孢子化卵囊含有 2 个孢子囊，每个孢子囊含有 4 个孢子虫。卵囊形态计量学与从家猫描述的猫贝蛔虫的已发表特征一致。部分线粒体细胞色素 c 氧化酶亚基 I（mtCOI）基因被 PCR 扩增和测序；得到的序列与来自家猫的猫贝蛔虫分离株显示出 100%的同一性。这是首次分子确认猫贝蛔虫感染并导致美洲虎幼崽出现临床明显的肠道疾病的报告。
