摘　　要：为揭示云南省边境地区虫媒病毒病的流行病学本底,2023年对云南省8个边境地区的1630份牛血清样品进行了蓝舌病病毒(BTV)和阿卡斑病毒(AKAV)抗体检测和数据分析。结果显示:BTV和AKAV平均阳性率分别为83.68%、6.87%,8个边境地区均检出BTV和AKAV抗体阳性样品;入境牛的BTV和AKAV抗体阳性率均显著高于本地牛(P<0.05);规模场的BTV抗体阳性率显著高于散养户(P<0.05);水牛的BTV抗体阳性率显著高于黄牛,黄牛的AKAV抗体阳性率显著高于水牛(P<0.05)。结果说明:云南省边境地区普遍存在BTV和AKAV感染,其中BTV感染较严重,但不同地区、不同来源、不同品种牛的感染情况存在差异。建议持续开展边境地区的虫媒病毒血清学监测工作,加大入境牛的检验检疫力度,督促养殖场户做好驱虫防虫工作,并不断提高其饲养管理水平。In order to reveal the epidemiological background of arboviral diseases in the border areas of Yunnan Province,1630 bovine serum samples collected from 8 border areas were detected for antibodies against bluetongue virus(BTV)and Akabane virus(AKAV),and the detection data were analyzed.The results showed that the average positive rates of BTV and AKAV antibodies were 83.68%and 6.87%,respectively,and positive samples of BTV and AKAV were detected in all the 8 areas;the positive rates of BTV and AKAV antibodies in imported cattle were significantly higher than those in local cattle(P<0.05);the positive rate of BTV antibodies on intensive farms was significantly higher than those on free-range households(P<0.05);and that of BTV antibodies in buffaloes was significantly higher than that in yellow cattle(P<0.05),but on the contrary was that of AKAV(P<0.05).In conclusion,BTV and AKAV were widely prevalent in the border areas of Yunnan Province,especially the former,but varied in different areas,sources and species of cattle.It was recommended to continuously carry out serological surveillance over arboviruses in the border areas,increase the inspection and quarantine for imported cattle,urge households/farms to make efforts in deworming and pest prevention,and to continuously improve their level of feeding management.
