【摘要】 鸡球虫病在我国广泛流行,严重影响我国养鸡业健康发展。目前各地关于鸡球虫流行情况均有报道,但鲜见关于全国整体流行情况的报道分析。本文对建国后各地的调查报告进行了梳理,发现我国各地鸡群球虫感染率均在50%以上,常见的虫种有柔嫩、巨型、堆型、和缓和毒害艾美耳球虫等,影响我国鸡球虫病流行的因素有饲养管理方式、环境及气候、免疫抑制或其他疾病、鸡只日龄等。同时我们还发现文献中检测鸡球虫的手段还比较落后,仅采用镜检球虫卵囊的占60%以上,并且调查范围局限于一市的占80%以上。由此可见,我国鸡球虫病流行严重,影响因素较多,而且流行病学调查手段落后、范围小,我们应当采用综合防控措施,并提高检测手段,以期控制鸡球虫病流行,促进养鸡业健康发展。更多还原

【Abstract】 Chicken coccidiosis is widespread and seriously affects the healthy development of the chicken industry in China. At present, there are lots of investigations on the occurrence of chicken coccidia in various places, but only a few reports on the overall epidemic situation in the country were presented. This paper sorted out the investigation reports after the founding of the People’s Republic of China and found that the infection rates of coccidia in chicken in all parts of China is above 50%. The common species are Eimeria tenella, E. maxima, E. acervulina, E. mitis and E. necatrix. The prevalence of chicken coccidiosis in China was influenced by feeding management, environment and climate factors, immunosuppression or other diseases, and age of chicken. At the same time, we also found that the means of detecting chicken coccidia in the literatures are too imprecise and simple to make proper diagnosis. More than 60% papers reported chicken oocysts detected only by microscopic observations and more than 80% papers limited the investigation scope within only one city even a town. More comprehensive prevention and control measures and improved detection methods should be taken to control the spread of chicken coccidia and promote chicken industry development in future.更多还原
