【摘要】：为了解国内羊肺炎支原体的流行情况,本研究应用正向间接血凝试验(IHA)对2014年~2015年间采自我国12个省44个市、县的3 402份未免疫血清样品进行了绵羊肺炎支原体(MO)、山羊支原体山羊肺炎亚种(Mccp)抗体的检测。结果显示:MO抗体阳性率为31.92%(1 086/3 402),其中阳性率最高的省份为内蒙古76.8%(636/828),其次是河北50%(60/120)、吉林21.99%(93/423);Mccp的抗体阳性率为10.67%(363/3 402),其中阳性率最高省份为河南35.14%(39/111),其次为河北27.5%(33/120)、山东22.5%(27/120);另有来自河北、辽宁、吉林、海南、黑龙江、内蒙古和安徽7省份的少量血清样品同时检测出MO和Mccp两种抗体,表明该病的流行存在不同菌株混合感染的情况,这在河北地区最为严重(15%)。分析表明,羊支原体肺炎在我国大部分地区流行相当严重,尤其在河北、河南和山东等集约化舍饲养殖发展的地区。绵羊的抗体阳性率明显高于山羊,表明MO在致病性和感染性方面相对Mccp更强。本研究为评估羊支原体肺炎在我国的流行状况以及制定有效防制措施提供了实验依据。
[Abstract]:In order to understand the prevalence of Mycoplasma pneumoniae in China, the positive indirect hemagglutination test (IHA) was used to study the prevalence of Mycoplasma pneumoniae from 44 cities in 12 provinces of China from 2014 to 2015. 3 402 unimmunized serum samples from county were tested for (Mccp) antibody of mycoplasma (MO), goat pneumonia subspecies. The results showed that the positive rate of Mccp was 31.92% (1 086 / 3 402). The highest positive rate was in Inner Mongolia 76.8% (636 / 828), followed by Hebei 50% (60 / 120), Jilin 21.99% (93 / 423) Mccp 10.67% (3 63 / 3 402). The highest positive rate was 35.14% (39 / 111) in Henan Province, 27.5% (33 / 120) in Hebei Province, 22. 5% (27 / 120) in Shandong Province. In Liaoning, Jilin, Hainan, Heilongjiang, Inner Mongolia and Anhui provinces, two antibodies, MO and Mccp, were detected simultaneously, indicating that there were mixed infections of different strains in the epidemic, which was the most serious in Hebei (15%). The analysis shows that Mycoplasma sheep pneumonia is very serious in most areas of China, especially in Hebei, Henan and Shandong provinces. The positive rate of antibody in sheep was significantly higher than that in goat, indicating that MO was stronger than Mccp in pathogenicity and infectivity. This study provides experimental basis for assessing the prevalence of Mycoplasma sheep pneumonia in China and making effective control measures.
