The incidence of Coccidia in Poland is discussed on the basis of examinations performed in 2391 pigs (1889 coproscopic and 502 post-mortem examinations) The three discovered Coccidia species were: Eimeria debliecki Douves, 1921, E. polita Pellerdy, 1949, and E. scabra Henry, 1931. The invasion extensivity is slight, mixed invasion occurring in the majority of cases. E. debliecki proved to be the most frequent and pathogenic species. The Coccidium fauna of pigs in Poland is poorer than that of other countries.
