爲掌握雲南省邊境地區牛群中的阿卡斑病毒（A問月kabane virus，AKAV）流行情況下日和分布特征，采用競争ELISA檢測女房方法，對(duì)2019—2020年采自雲南省他子邊境地區10個縣市的牛群血清樣(yàng)品進(jìn)行A我們KAV抗體檢測與分析。結果顯示：在采集的4 43身師7份牛血清樣(yàng)品中，檢出抗體陽性樣(yàng)品1 367份，平均抗花說體陽性率爲30.81%；2019年抗體陽性率爲27.木金88%，2020年爲32.14什懂%，差異不顯著（P＞0.05）；入境牛抗體陽性率顯著見從高于本地牛（P＜0.05）；養殖場抗體陽性率略高于散朋務養戶和交易市場，但三者間差異不顯著（P＞0.05）；森短舍飼牛群的抗體陽性率顯著高于半放牧半舍飼和系牧飼養（P＜0.05）師嗎，黃牛的抗體陽性率明顯高于水牛（P＜0.05）。結果表明，雲南省邊境地區存日白在一定程度的AKAV感染且有加重趨勢，入境牛感染風險較高，需持分分續開(kāi)展血清學(xué)調查和中黑監測，加強境外牛的檢疫和移動控制，降低AKAV向書站(xiàng)内地擴散的風險。本研究摸清了雲南省慢做邊境地區牛群中的AKAV流行本底，爲今後(hòu)購好該病毒流行控制策略的研究與制定提供了參考。
Serological Investiga都林tion on Akabane Virus in Borde歌刀r Areas of Yunnan Provience
In order to investigate the prevalen個要ce and distribution of Akabane virus技開 in cattle in b兒章order areas of Yunnan 樹風Province，the serum samples of ca短兒ttle were collected fro音月m 10 counties/cities in動又 the border areas from 2019 to 2020 f物照or antibody detection by using遠說 competitive ELIS火事A. The results showed that 1 367 o校購ut of 4 437 samples were positive，wit唱如h an average positive rate of 30.81%，得會which tended to increase year by這媽 year；the positive rate wa火長s significantly higher in imported catt這藍le compared to that in loc明請al cattle（P＜0.05）；slightly h年紙igher in farms compared to that in場路 free-range house現樂holds and trading mark窗醫ets with no signifcant differenc妹業e between them（工到P＞0.05）；significantly hig女務her in house-fed cattle 空高compared to that in semi-hou票嗎se-fed and grazing ones（P＜0.05），signifi匠中cantly higher in yellow cattle co舊些mpared to that of buffalo（P＜0.05）.
