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.
