Abstract

The prevalence of coccidiosis was determined and Eimeria species were identified in farms at different locations in the Bejaia region, Algeria. The study was conducted from February to December 2016. Unvaccinated birds were selected randomly. Samples from litter and faeces were collected randomly (147 and 109, respectively). Necropsy and parasitological examinations were carried out using standard methods. Of the samples examined, 93 out of the 147 litter samples and 78 out of the 109 intestinal content samples were infected with Eimeria oocysts (63.26% and 71.55%, respectively). Mixed infections with Eimeria spp. were observed in some of the positive farms, with an overall prevalence of 54.28%. Five species of Eimeria (viz. E. acervulina, E. tenella, E. maxima, E. brunetti and E. mitis) were identified with different indices. Eimeria acervulina followed by E. tenella were the predominant species infecting chickens at the farms visited (32.05% and 26.92%, respectively). Statistically, the most prevalent Eimeria spp. was E. Acervulina (p < 0.05). This study demonstrated that coccidiosis is an omnipresent parasitic intestinal disease. It could strongly decrease production performance in broiler chickens.
