Cyclospora spp. in nonhuman primates are most closely related to Cyclospora cayetanensis, an emerging human pathogen causing outbreaks of cyclosporiasis in North America. Studies thus far indicate the possible existence of host specificity in Cyclospora spp. In this study, 411 fecal specimens from free-range rhesus monkeys (Macaca mulatta) were collected and examined for Cyclospora by sequence analysis of the small subunit rRNA gene. A novel Cyclospora species was identified in 28 (6.8%) specimens and named Cyclospora macacae based on morphologic and molecular characterizations. The oocyst of C. macacae is spherical and measures 8.49 ± 0.55 × 8.49 ± 0.49 µm in diameter. Phylogenetic analysis grouped this species together with the other four Cyclospora species infecting primates, including C. cayetanensis in humans, forming a monophyletic group closely related to avian Eimeria species. In addition, C. cayetanensis was detected in one specimen, although whether rhesus monkeys can serve as a natural reservoir host of C. cayetanensis needs further investigation.
