The results showed that coccidian oocysts were found in 74.4% of 86 faeces samples from 16 goose flocks. Six species of coccidia, Eimeria anseris, E. fulva, E. hermani, E. nocens,E. stigmosa and Tyzzeria parvula were identified. In the experiments of artificial infection three of four 12-day-old coccidia-free goslings were died after inoculated with mix oocysts of 5×10~4. Pure oocysts of 5 Eimeria species
were obtained then, respectively, laying the basis for studies of their life cycles and pathog enicity
