| 摘 要： | 用血凝抑制试验检测了我国奶牛、黄牛、水牛、牦牛、绵羊、山羊、猪和人共1733份血清中的牛冠状病毒(BCV)抗体,其阳性率分别为80.2%,67%,23.2%,44.3%,5.3%,0%,19%和19.3%。奶牛血清 BCV 抗体有年龄差异,黄牛、水牛、牦牛及人等抗体检出率存在地区性差异。结果表明,BCV 在我国普遍存在,可能为犊牛及成年牛腹泻的重要病原之一。

| Abstract: | A serocpizootiological survey of bovine coronavirus(BCV) in cattle,buffalo,yak,sheep,goat,swine,and human in China,by means of heamagglutination inhibition(HI)test,was reported.Of 560 serum samples from 6 dairy herds,449(80.2%) were BCVantibody positive.Among these,the adult cows had high positive rate(97,2%),while thecalves were lower(16.3%).The HI titer of 379 samples were higher than 160.Of 443draft cattle serum samples from 7 herds,279(67%) were positive.The positive rate in buf-falo was very different in two counties(47% and 8.9% respectively).The BCV antibodieswere detected in yak,the rate of positive sera from Xingjiang,Sichun,and Qinghai were28%,16.7%,and 94.4% respectively.The positive rate of BCV antibody in sheep,goat,and swine were 5.3%,0%,and 19% respectively.The positive rate(3.4%) of people livedin cities was much lower than that in rural area (63.2%).It was suggested that the BCVwas widespread in China,and might be one of the important pathogenic agents causingcalf diarrhoea. |
