Abstract :

  In this study which was conducted from ordibehesht 1389 to mehr 1390, a total of 265 wild rabbits were investigated from which 117(44.2%) were contaminated with eimeria protozoa.in this study,the contamination of wild rabbits,mature and immature,abundance of Coccidiosis,geographically disturbed and common species,sexual distribution rate in the host,and the rate of excreted oocytes and its relation with onset of contamination,its effect on age and number of eimeria species responsible for onset of the disease,and etc. were evaluated.the contamination percentage of positive samples of each province compared to total samples of the province were observed to be 80.2% for Adabil,87.2% for Western Azarbayjan, and 76.2 for Eastern Azarbayjan.results showed that among the investigated immature rabbits,91 were contaminated with Eimeria.mean of oocytes excreted in mature rabbits was 35.53 per gram of feces.but this amount was 30.18 per gram of feces for immature rabbits.contamination in immature rabbits was more than mature rabbits and this relation was significant(p=0.0490 and  p=0.0348).
