摘　　要：为了解云南省边境地区牛猪口蹄疫(FMD)控制情况,2023年在跨境动物流动频繁的8个边境县市设置监测点,采集牛血清样品1630份、猪血清样品830份,分别进行了O、A型口蹄疫病毒(FMDV)免疫抗体检测,并对检测结果进行了统计分析。结果显示:牛群O、A型FMDV抗体阳性率分别为71.17%、80.12%,猪群分别为31.33%、26.27%;统计分析发现,牛规模场O、A型FMDV抗体阳性率均低于散养户,但无统计学差异(P>0.05);入境牛O、A型FMDV抗体阳性率分别为70.29%、89.14%,本地牛分别为71.37%、77.98%,入境牛的A型抗体阳性率显著高于本地牛(P<0.05)。结果说明:牛群FMD免疫水平达到国家要求,但猪群免疫水平较低。建议云南省边境地区持续开展FMD血清学监测,着重提高牛规模场和猪群的FMD免疫密度和强度,加大走私牛查处力度,严防FMDV传入和扩散。In order to investigate the control status of bovine and porcine foot-and-mouth disease(FMD)in border areas of Yunnan Province,surveillance sites were set up in 8 border counties/cities with frequent cross-border animal movement in 2023,and 1630 bovine and 830 porcine serum samples were collected to detect antibodies against FMD virus(FMDV)types O and A,followed by statistical analysis of the results.The results revealed that the antibody positive rates of FMDV types O and A were 71.17% and 80.12% in cattle herds,respectively,and 33.13% and 26.27% in pig herds,respectively.Statistical analysis results indicated that the positive rates of FMDV types O and A in intensive cattle farms were both lower than those in smallholders'farms,without statistical significance(P>0.05).The positive rates of FMDV types O and A in imported cattle were 70.29% and 89.14%,respectively,whereas those in local cattle were 71.37% and 77.98%,respectively,and the rate of FMDV type A was significantly higher(P<0.05)in the former compared to the latter.In conclusion,the immunization level of FMD in cattle herds reached national standard,but that in pig herds was lower.Therefore,continuous FMD serological monitoring was recommended to be carried out in the border areas of Yunnan Province,giving a priority to improving the immunization density and intensity in intensive cattle farms and pig herds,and intensifying the investigation and punishment against smuggling activities related to cattle to strictly prevent any introduction and spread of FMDV.
