AB  - This study was conducted on 1090 chicks (2-6 weeks of age) from 218 broiler farms stayed in Tabriz northwest of Iran. These chicks were submitted for post-mortem and parasitological examinations. Five <I>Eimeria</I> sp. were identified: <I>E. acervulina</I>, <I>E. tenella</I>, <I>E. necatrix</I>, <I>E. maxima</I> and <I>E. mitis</I>. The overall prevalence of <I>Eimeria</I> sp. among examined farms was 55.96% (122 of 218 farms). <I>E. acervulina</I> was the most prevalent species (23.58%). Prevalences did not vary by flock size. Also, neither the use of coccidiostat nor previous coccidiosis clinical outbreaks were associated with the prevalence of infestation. The prevalence of infestation increased with the age of the chickens. Chickens with 5 weeks of age showed the highest prevalence of infestation.
