| Abstract: | A study of coccidian parasites in British wild birds was undertaken and faecal samples of 5568 birds, representing 141 bird species from 40 families, were examined. Oocysts were found in 18.68% of the samples. Species of the genera Isospora (16.90% infection), Eimeria (1.24% infection), Caryospora (0.48% infection) and Tyzzeria (in three samples) were identified. The overall prevalence of infection did not appear to be influenced by the sex and age of the host. The results are discussed in the light of the general knowledge of coccidian infections. |
