Abstract
The current study examined the prevalence of Eimeria infections in domestic rabbits in China. A total of 480 faecal samples were collected from 48 farms in 14 provinces of China. Each faecal sample was subjected to oocyst counting and oocyst isolation. The Eimeria species from samples containing isolated and sporulated oocysts were morphologically identified under microscope. The overall prevalence of infections was 41.9% (201/480). Northwest China had the highest prevalence (70%), followed closely by Northeast China (65%) and Southwest China (62.5%). The prevalences in North China (34%) and South China (25.8%) were significantly lower. The large and medium farms had lower prevalences (34.2% and 37.2%, respectively) than the small farms (61.4%). Coccidian oocysts were found in 42.2% (76/180) of faecal samples from meat rabbits, 40% (28/70) from angora rabbits and 44.7% (85/190) from Rex rabbit. In total, ten species of Eimeria were identified from oocyst-positive samples. Concurrent infection with two to eight Eimeria species was found. E. perforans was the most prevalent species (35.2%), followed in order by E. media, E. magna, E. irresidua and E. intestinalis with prevalences of 31.3%, 28.8%, 19.4%, and 14.8%, respectively. Taken together, These results reveal the characteristics of the prevelance of rabbit coccidia infection in China, including the distribution, the scale of farming and the species, which are indispensable to the control of rabbits coccidiosis in China.Keywords
