【摘要】：2014年本实验室在广西分离获得一株中山病病毒,表明中山病在我国已经存在。为调查中山病在我国的流行分布状况,本实验采用经典的病毒微量中和试验方法,对我国黑龙江、内蒙古、新疆、山东、江苏、湖北、广西、云南和海南等9个省区的543份牛羊血清进行检测。其中,海南68份牛羊血清样品中阳性样品39份,阳性率高达57.35%;黑龙江的80份样品检测结果均为阴性;其他各省的血清阳性率介于6%~48.65%。结果表明,目前被调查的9个省区除黑龙江省外均存在中山病的流行,南方的感染率较高;对新疆、湖北、广西、云南4个省自治区牛和羊的易感性进行比较,除新疆外,牛的阳性率均比羊高,牛血清阳性率6%~58.5%,羊16.67%~33.33%;对不同季节中山病感染率进行比较,结果显示,秋季(9~11月)感染率(16.67%~43.33%)最高,明显高于春季和夏季。由于采集的血清来自具有代表性的省份,以上研究结果表明,中山病在我国的流行具有广泛性。
[Abstract]:A strain of Zhongshan disease virus was isolated in Guangxi in 2014, indicating that Zhongshan disease exists in China. In order to investigate the epidemic distribution of Zhongshan disease in China, the classical virus neutralization test method was used to study the prevalence of Zhongshan disease in Heilongjiang, Inner Mongolia, Xinjiang, Shandong, Jiangsu, Hubei, Guangxi, China. 543 serum samples of cattle and sheep from 9 provinces including Yunnan and Hainan were detected. Among them, 39 were positive in 68 cattle and sheep serum samples in Hainan, the positive rate was as high as 57.355,80 samples in Heilongjiang were negative, and the positive rates in other provinces were between 68.65 and 48.65. The results showed that the prevalence of Zhongshan disease existed in all the nine provinces and regions, except Heilongjiang Province, and the infection rate in the south was relatively high, and the susceptibility of cattle and sheep in Xinjiang, Hubei, Guangxi and Yunnan provinces was compared, except Xinjiang. The positive rate of cattle was higher than that of sheep. The positive rate of bovine serum was 58.5 and 16.677.The infection rate of Zhongshan disease in different seasons was higher than that of sheep. The results showed that the infection rate of Zhongshan disease in autumn was the highest, which was significantly higher than that in spring and summer. Since the serum samples were collected from representative provinces, the results show that the prevalence of Zhongshan disease in China is widespread.
