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。
CCPP is a selective immunization ened animal was carried out, resulting in project,and emergency vaccination only when threat- increasingly serious epidemic disease. MCCP antibody levels in 12 provinces 42 regions of China from 2014 to 2015 were monitored. 878 serum samples were surveyed, 112 were antibody-positive, the average positive rate is 12.76 %. In addition, MCCP serum antibodies were detected in the other provinces except for Shanxi province, and antibody positive rate in Henan,Hebei,Shandong were 35.14%（13/37）,27.5%（11/40） and 22.5% （9/40） respectively, that of J iangsu province was the lowest which was 2.7 % （1/37）. Qualitative analysis showed that when the serum ＂4-＋＋ ＋＋＂from 112 positive titer reached 1 ： 16,30 samples can be judged as ＂＋＋＋＋＋＋＋＋＂and 42 as serums, Quantitative analysis of 18 strong positive serum samples showed that MCCP serum antibody titer was up to I .＂ 256. MCCP infection in some districts of our country is very serious, especially in Henan, Hebei and Shandong.
