摘　　要：为了了解和掌握鸡毒支原体(Mycoplasma galliscepticum,MG)在福建省近年的感染情况,本研究采用商品化ELISA抗体检测试剂盒对2018-2019年福建地区的21个鸡群、916份非免疫鸡群血清样品进行MG抗体检测,并统计分析MG在福建省感染流行情况。调查结果发现,2018-2019年福建地区非免疫鸡群的MG抗体总阳性率为69.43%(636/916),而检测的21个鸡群中,群体MG抗体阳性率为90.48%,其中阳性率0%~20%的有4个,21%~50%的有4个,51%~100%的有13个。育雏阶段(1~42日龄)鸡群MG抗体阳性率就高达37.10%,并且发现产蛋开始至淘汰阶段MG抗体阳性率为77.61%,MG抗体阳性率是育雏阶段的2倍以上。福建省蛋鸡和种鸡群MG感染率分别为79.22%和75.22%,并无显著差异。通过福建地区未免疫鸡群的MG抗体调查,发现MG在福建省内感染普遍,表明病原在鸡群中存在水平传播,同时种鸡群也存在着严重的MG感染,这为垂直传播提供可能。本研究通过调查福建省内MG在鸡群中的感染情况,为掌握MG在鸡群中的感染情况并采取防控措施降低鸡群MG感染率提高防治效果奠定基础。To investigate the infection of Mycoplasma gallisepticum(MG)in laying hens and breeders in Fujian province from 2018 to 2019,and provide scientific basis for the monitoring of MG.A commercial ELISA kit was used to detect MG antibody in 916 serum samples from 21 chicken flocks in Fujian province from 2018 to 2019,the epidemic law of MG in Fujian province was analyzed.From 2018 to 2019,the total positive rate of MG antibody was 69.43%(636/916)in non-immune chicken flocks in Fujian province,and the positive rate of MG antibody was 90.48%in 21 chicken flocks detected,among which 4 flocks with positive rate of 0%~20%were detected,in 21%~50%of 4,51%~100%of 13.At the brood stage(1-42 days old),the positive rate of MG antibody was as high as 37.10%,and it was found that the positive rate of MG antibody was 77.61%from the beginning of laying to the phase of culling,the positive rate of MG antibody was more than 2 times of that of brood stage.The infection rates of MG in layers and breeder flocks were 79.22%and 75.22%,respectively.The investigation of MG antibody in unvaccinated chicken flocks in Fujian province shows that MG infection is common in Fujian province,and the pathogen is transmitted horizontally in the chicken flocks.MG infection also exists in breeder flocks,which makes vertical transmission possible.This study investigated the infection of MG in chicken flocks in Fujian province,and laid a foundation for taking preventive and control measures in time,reducing the infection rate of MG in chicken flocks and improving the control effect.
