Abstract: 

In this study, 380 broilers were investigated from the view point of prevalence and histopathological changes of coccidiosis and coccidiasis in mahabad. The prevalence of coccidiosis and coccidiasis was determined 6.9 in 100000. In parasitological investigation, frequency of oocystes in wet slide method and floatation were 17.1 % and 36.3 % and the frequency of coccidiasis, coccidiosis and total frequency of parasitic enteritis were 26.3 % , 10 % and 36.3 % respectively. In histopathological investigation the frequency of mucosal edema, sub mucosal edema, hemorrhage, enterocyte hyperplasia, necrosis, oocyste observance in mucus and inflammatory cell infiltration were 74/2 %, 45/3 %, 25/3 %, 30/8 %, 27/1 %, 10 % and 18/2 % respectively. The high frequency of coccidiasis and coccidiosis after 4 and 7 weeks were 21 % and 42/1 % respectively. It was also found that there is a direct relationship between parasitical enteritis and food convertion rate and therefore meat production from food shows a bit decline. A meaningful relationship between different segment of intestine and parasitical enteritis was found that one of the Eimeria species produced enteritis in the duodenum. The statistics methods of analysis in this study have been done by SPSS soft ware.
