    摘要:

    2015年9月27日,河南省郑州市某鸡场饲养的育成期蛋鸡发生未知原因的突然大量死亡。为查明病因,控制疫情,开展了此次调查。通过询问饲养管理人员、查看现场、剖检及实验室检测和流行病学分析等方法,对该次暴发进行了流行病学调查。根据临床症状、剖检及镜检结果,同时结合实验室检测结果,确诊该起疫情为鸡球虫感染。通过氟苯尼考拌料,对圈舍消毒,清理粪便,疫情迅速得到控制。分析发现,有球虫病发病史、引进鸡只不检疫、驱虫措施不科学、粪便清理不及时是导致鸡球虫感染的主要风险因素。建议引进鸡时加强检疫,定期对鸡群进行驱虫,加强粪便清理及无害化处理,从而降低鸡球虫病的发生。

    Abstract:

    On September 27,2015,sudden mass mortality of chickens in rearing stage occurred for unknown reason in a chicken farm in Zhengzhou city of Henan province. In order to identify the cause and control the disease,an outbreak investigation was carried out. The epidemiological survey was conducted by adopting the following methods,which included asking the feeders,viewing on the spot,animal autopsy,laboratory detection and epidemiological analysis. Based on all of the above detection results,the cause of the disease was confirmed as chicken Coccidia infection. And the outbreak was controlled quickly by mixing feed with florfenicol,disinfecting the poultry houses and cleaning up feces. In view of the analysis,the main risk factors of chicken Coccidia infection were various,including the history of Coccidiosis in this farm,lack of inspection and quarantine when the chickens were introduced,unscientific measures for expelling parasites,as well as not timely cleaning feces. In order to reduce the occurrence of chicken Coccidiosis,corresponding countermeasures were proposed:strengthening quarantine towards the introduced chickens,expelling parasites regularly,cleaning up feces and strengthening bio-safety disposal.
