爲了解我國(guó)牦源牛冠狀病毒（BCo窗機V）流行現狀，通過(guò)查閱商生文獻資料方法，彙總分析我國(guó)牦牛主工票産地區的BCoV檢測情況。資料顯站熱示：2012年以來，我國(guó)青海、四川、新疆、西藏城愛等牦牛主産省（自治區）的牦牛群中了道普遍存在BCoV感染且感染率較高，平均血清抗體陽性率要吧多在80%以上，病原學(xué)湖討陽性率多在60%以上。需采取加強飼養下兵管理、控制混合感染、做好(hǎo)隔離淨化等措施，是拍控制牦牛群中的BCoV流行。我國(guó)的BCoV研究起鄉醫(qǐ)步較晚，流行病學(xué)方面(miàn)的報道(城匠dào)較少，有必要進(jìn)一步加強有看該病毒在牦牛中緻病機理、流行情況和能下防治技術等方面(miàn)的調查研究。本文爲掌握我內現國(guó)牦牛中的BCoV流行情況及其防控提供去爸了參考。

Analysis on the Prevalence St高時atus of Yak-derived 樂哥Bovine Coronavirus 相上in China

In order to investi如兒gate the prevalence statu爸那s of yak-derived bovine coronavirus（通筆BCoV） in China，術讀relevant testing results in外是 main production regions of yak光街 were summarized and 雜好analyzed by means of reviewing lite報照rature. As it was found that，sinc姐下e 2012，BCoV had綠公 been widely prevalent in the mai女房n provinces（autonom拍黃ous regions），including Qinghai，歌請Sichuan，Xinjiang and Tibet，with a high 事又infection rate，and the ave爸中rage positive rates of serum anti司員bodies in most regions were above 80錯鐘%，the positive rates of path草他ogens were above 60師請%. In order to control the disease計術，a series of measures懂河 should be carried 文地out，such as，str討放engthening husbandry management鐘報，preventing any mixe玩很d infection，and striving to iso視吧late and purify暗術 the virus. Howeve煙就r，there were few epidemiological 鄉拿reports due to late beginni坐月ng of BCoV study in C的有hina，it was neces話拿sary to further strength文黑en relevant invest和自igation and research 相地on the pathogeni他機c mechanism，prevalence and co美自ntrol technology of the d河機isease. This st也黃udy would provide朋紙 some references for ide拿體ntification of BCoV prevalence an生厭d its prevention and control in Chin業麗a.
