Abstract: The fresh chicken feces were collected from invesgation points of 3 locations of Liuan, Shouxian and Huoqiu by population sampling method for feces detection. The oocysts were isolated from positive feces samples by saturation salt solution float method and centrifugal sedimentation method. The oocysts were obserVed under microscope for species identification and the infection rate and intensity of chicken coccidia of all the investigation points were calculated. The results indicated that in the 50 checked fresh chicken feces samples, the infection rate of chicken coccidia was 100 %, 6 species of coccidia were detected and they were E. necatrix, E. acervulina, E. maxima, E. tenella, E. mitis and E. praecox of the genus Eimeria resp. It was illustrated that chicken coccidia was universial in west Anhui region and in some investigation points, its infection intensity was very high and the scientific control awareness of raising households was not strong.
