بررسي عوامل كوكسيديايي خرگوش (نژاد نيوزلندي سفيد) در مركز نگهداري حيوانات آزمايشگاهي دانشگاه اروميه

This survey was carried out to determine species of Eimeria and prevalence rate from 59 laboratory rabbits (New Zealand White) on which were breed by cage (24) and litter (35) breeding system during summer in 2001. The overall prevalence of infection (1.16 %; OPG = 69.5) in litter breeding system was significantly higher than cage breeding system (0.59 %; OPG =11), (p<0.05). There were two forms of subclinical coccidiosis (intestinal and hepatic) in litter breeding system meanwhile in cage breeding system was only subclinical intestinal coccidiosis. Eimeria piriformis (37.6%), E. performans{30A%), E. nagoporensis(25.6%), E. irresidua (2.4%), and E. stiedai (4%) in litter breeding system and Eimeria nagoporensis (374%), E. performans (34.6%) , and E. piriformis{30.4%) in cage breeding system were recorded in descending order of frequency.
