流行病学研究可以充分协助设计疾病控制的预防策略。本研究于2016年7月至9月在中国安徽省调查鸡中艾美耳球虫的流行情况。共对171份样品进行了显微检查和分子检测。安徽省球虫病患病率为87.75%（150/171）。以细艾美耳球虫（80.67%,121/150）为最常见种，中性艾美耳球虫、中性艾美耳球虫、大艾美耳球虫、布氏艾美耳球虫和尖角艾美耳球虫分别为68%（102/150）、55.33%（83/150）、54.67%（82/150）、44.67%（67/150）和2.67%（4/150）。未检出早艾美耳球虫。最常见的组合为柔嫩埃希菌、最大埃希菌、蛇颈埃希菌、布鲁内蒂埃希菌和米提埃希菌（26.67%,40/150），其次为柔嫩埃希菌、最大埃希菌和蛇颈埃希菌（19.33%,29/150）。网状艾美耳球虫在多重感染中的参与率最高。本研究结果提示，安徽省鸡群球虫感染呈混合性、重度、广布性，应采取综合防治措施。
Prevalence studies can adequately assist in the design of prophylaxis strategies for disease control. Here, the prevalence of Eimeria species in chickens was investigated in Anhui province, China, from July to September 2016. A total of 171 samples were tested by microscopic examination and molecular methods. The prevalence of coccidiosis in Anhui province was found to be 87.75% (150/171). Eimeria tenella was the most prevalent species (80.67%, 121/150), and Eimeria necatrix, Eimeria mitis, Eimeria maxima, Eimeria brunetti and Eimeria acervulina were 68% (102/150), 55.33% (83/150), 54.67% (82/150), 44.67% (67/150) and 2.67% (4/150), respectively. Eimeria praecox was not detected at all. The most common combinations are E. tenella, E. maxima, E. necatrix, E. brunetti and E. mitis (26.67%, 40/150), followed by E. tenella, E. maxima and E. necatrix (19.33%, 29/150). Eimeria necatrix exhibited the highest participation in multiple infections. The results of the present study suggested that Eimeria infection is mixed, severe and widespread in chickens, Therefore, integrated strategies should be performed to prevent and control coccidial infection in chickens in Anhui province.
