摘要
研究旨在了解重大动物疫病防疫效果,于2020—2022年采集畜禽血清样品5596份,通过ELISA、HA/HI试验进行血清学抗体检测。结果显示:2022年春季猪、牛、羊O型口蹄疫及牛A型口蹄疫、小反刍兽疫、禽流感H5N6 H5Re-13株、禽流感H7N9 H7Re-4株抗体合格率分别为87.57%、93.53%、95.56%、92.23%、93.41%、93.55%、94.24%。与其他病种相比,猪O型口蹄疫防疫需进一步加强;周期内重大动物疫病防疫状况整体良好,但不同区域、不同病种及不同年份抗体合格率存在差异,禽流感免疫抗体合格率不稳定,牛A型口蹄疫抗体合格率呈持续下降趋势。研究表明,今后应加强猪O型口蹄疫、牛A型口蹄疫及禽流感防疫效果的动态监测。
The aim of the study was to understand the effect of epidemic prevention on major animal diseases.A total of 5596 serum samples of livestock and poultry were collected from 2020 to 2022,and serological antibodies were detected by ELISA and HA/HI tests.The results show that in the Spring of 2022,the qualified rates of antibodies against foot-andmouth disease type O in pigs,cattle and sheep,foot-and-mouth disease type A in cattle,Pester Petit Ruminant,avian influenza H5N6 H5Re-13 strain and avian influenza H7N9 H7Re-4 strain were 87.57%,93.53%,95.56%,92.23%,93.41%,93.55%and 94.24%,respectively.Compared with other diseases,the prevention of porcine foot-and-mouth disease type O needs to be further strengthened.The epidemic prevention of major animal diseases in the cycle was good on the whole,but the qualified rate of antibody was different in different regions,different diseases and different years.The qualified rate of antibody to avian influenza was unstable,and the qualified rate of antibody to bovine foot-and-mouth disease type A showed a continuous decreasing trend.The study indicates that in the future,dynamic surveillance of swine foot-andmouth disease type O,cattle foot-and-mouth disease type A and avian influenza should be strengthened.
