The main goal of current study was to investigate the prevalence of coccidiosis in broiler farms in Hamedan province, western Iran. Chicks and fecal samples were collected in all of the 220 broiler farms in this region. All viscera were examined for gross pathological changes. The mucosa of small intestine and the caeca were examined for the presence and identification of parasitic forms using parasitology methods. The overall rate of coccidiosis was 31.8%; E. acervulina (75.7%), E. tenella (54.3%), E. necatrix (28.6%), and E. maxima (20%) were determined. Mixed infections were observed in all of the positive farms. There was a statistical significant difference (P < 0.05) among infection rate and age groups, dysentery, history of colibacilosis and clostridiosis in farm, and history of coccidiostats consumption, unlike to breed (P > 0.05). This is the first report of coccidiosis rate in broiler farms in this region. Further additional researches and design control strategies for improving management in farms are necessary.
本研究的主要目的是调查伊朗西部哈马丹省肉鸡场球虫病的流行情况。在该地区的220个肉鸡场采集了雏鸡和粪便样本。检查所有内脏的大体病理变化。使用寄生虫学方法检查小肠和盲肠黏膜，以确定是否存在寄生虫形态并进行鉴定。球虫病的总体发生率为31.8%；已确定堆型艾美耳球虫（75.7%）、柔嫩艾美耳球虫（54.3%）、毒害艾美耳球虫（28.6%）和巨型艾美耳球虫（20%）。在所有阳性鸡场均观察到混合感染。感染率与年龄组、痢疾、鸡场大肠杆菌病和梭菌病病史以及抗球虫药使用史之间存在统计学显著差异（P<0.05），但与品种无关（P>0.05）。这是该地区肉鸡场球虫病发生率的首次报告。有必要进一步开展研究并设计控制策略以改善鸡场管理。
