摘要
2006年3-5月份,山东某一大型AA父母代肉种鸡场孵化场出现胚胎死亡、弱雏增多、种鸡和商品鸡有呼吸困难等症状。为了探明其病因,我们用血清平板凝集试验（SPA）进行了血清流行病学调查以及一系列病原的分离鉴定。结果显示,出现上述现象的原因主要是由一株致病力很强的MG-S6感染种鸡后,由种蛋垂直传播给鸡胚、雏鸡引起的。据此了解CRD在AA肉鸡中的流行状况,从而为种鸡场净化霉形体提供理论依据。
A kind of disease appeared in one large - scale AA broiler breeder farm in Shandong Province with the symptom of embryo death, increase of weak chicken, respiratory difficulty of broider breeders and chickens from March to May 2004. Based on the epidemiology investigation with SPA and the pathogenic Isolation and identification,, The results showed that the MG -S6 was the major cause of the disease. This pathogen spreads vertically from the eggs to the embryos. According to the analyse of epidemiology of CRD , and thus will provide a theoretical basis of purification Mycoplasma for the AA broiler breeder farm
