摘　　要：为了解陕西省略阳乌鸡种鸡场鸡白痢(Pullorum Disease,PD)、鸡滑液囊支原体(Mycoplasma synoviae,MS)和鸡毒支原体(Mycoplasma gallisepticum,MG)的流行情况,利用估计流行率的抽样方法对略阳乌鸡种鸡场开展了调查。结果显示,略阳乌鸡种鸡场鸡白痢个体阳性率为4.73%(95%CI:3.1%~6.9%);滑液囊支原体个体阳性率为65.82%(95%CI:61.7%~69.8%);鸡毒支原体个体阳性率为64.91%(95%CI:60.8%~68.9%)。风险因素调查发现,种鸡场内三种疾病的感染受到饲养管理方式、消毒措施以及长期不当使用抗菌药物等因素的影响较大。因此,在实施种源病净化时,应重点考虑这些因素,以更好地控制鸡白痢、鸡滑液囊支原体和鸡毒支原体等种源性传染病的流行。To understand the prevalence of Pullorum Disease(PD),Mycoplasma gallisepticum(MG)and Mycoplasma synoviae(MS)infections in breeding farms of Shaanxi province,an investigation was carried out at Lueyang Breeding Chicken Farm by using the sampling method to estimate prevalence.The results showed that the individual positive rate of PD,MG and MS in the farm were 4.73%(95%CI:3.1%~6.9%),64.91%(95%CI:60.8%~68.9%)and 65.82%(95%CI:61.7%~69.8%),respectively.The investigation of risk factors found that the infection of the three diseases in the breeder flock was greatly influenced by factors such as breeding methods,disinfection practices,and prolonged misuse of antibiotics.Therefore,when implementing avian embryo purification measures,these factors should be given priority to better control the spread of diseases like Pullorum Disease and avian mycoplasmosis.
