Eight Eimeria spp. (Apicomplexa: Eimeriidae) have been isolated from the ring-necked pheasant (Phasianus colchicus Linnaeus), native to the temperate zone of Asia and eastern regions of Europe. Enteric coccidiosis has become a major issue associated with the breeding of farmed pheasants for game bird release or meat production.

- A parasitological study was conducted on the gastrointestinal tracts of farmed ring-necked pheasants in Ehime, Japan, examining fecal samples for various parasites over three years.
- The findings included a high prevalence of coccidian oocysts, capillarid worms, and heterakid eggs, with a detailed analysis revealing a specific type of coccidian, Eimeria phasiani.
- Sequencing of mitochondrial and ribosomal genes identified several nematode species present, with notable genetic similarities to other pheasant parasites, marking the first characterization of certain genetic sequences in this context.
