【摘要】：山羊支原体肺炎(CCPP)为选择性免疫项目,只有受到威胁时才紧急免疫接种,导致该病的流行日趋严重,通过对2014-2015年我国12个省42个地区山羊支原体肺炎山羊亚种(MCCP)血清抗体水平的监测分析我国目前MCCP的流行趋势、流行原因。被调查的878份血清样品中,有112份为抗体阳性,平均阳性率12.76%。目前除山西省没有检测到MCCP血清抗体外,其余省份均有MCCP的流行,其中河南、河北、山东3个省份抗体阳性率最高,分别为35.14%(13/37),27.5%(11/40)及22.5%(9/40);江苏省是阳性率最低的省份,阳性率为2.7%(1/37);定性分析结果显示:当血清效价达到1∶16时,112份阳性中,30份可判定为"++++",42份为"+++";对18份强阳性血清样品定量分析结果显示:CCPP血清抗体效价最高可达1∶256。可见,2014-2015年间,MCCP引起的CCPP在我国流行非常严重,尤其河南、河北、山东等省份,不仅为准确评估MCCP在我国现阶段的流行状况以及造成的危害提供参考,也为有效防控该病提供技术支撑。
[Abstract]:Mycoplasma suis pneumonia (CCPP) is a selective immunization project. It is only vaccinated urgently when it is threatened, which results in the epidemic of the disease becoming more and more serious. Based on the surveillance of (MCCP) antibody level of goat mycoplasma pneumoniae subspecies in 42 regions of 12 provinces in China in 2014-2015, the epidemic trend of MCCP in China and the epidemic reasons were analyzed. Of the 878 serum samples investigated, 112 were antibody positive, with an average positive rate of 12.76. At present, with the exception of Shanxi Province, all other provinces have the prevalence of MCCP. The positive rates of MCCP in Henan, Hebei and Shandong provinces are the highest, 35.14% (13 / 37) and 27.5% (11 / 40) and 22.5% (9 / 40), respectively. Jiangsu Province is the province with the lowest positive rate. The positive rate was 2.7% (1 / 37). The qualitative analysis showed that 30 out of 112 positive samples could be identified as "42 positive" when the titer of serum reached 1:16, and the quantitative analysis of 18 strong positive serum samples showed that the serum antibodies against CCPP were 20%. The titer can be as high as 1: 256. It can be seen that CCPP caused by MCCP in 2014-2015 is very serious in China, especially in Henan, Hebei, Shandong and other provinces. It not only provides a reference for accurately evaluating the epidemic situation and harm caused by MCCP at this stage in our country. It also provides technical support for effective prevention and control of the disease.
