摘　　要：为了解湖南省家畜布鲁氏菌病(简称布病)流行情况,从“全国动物卫生监测平台疫病监测系统”数据库中,下载2014-2022年湖南省布病监测数据,使用SPSS软件进行统计分析。结果显示:2014-2022年全省共对22 544个场点的594 180份血清样品进行了布病抗体检测,共检出阳性样品4 381份,个体阳性率为0.74%(95%CI:0.72%~0.76%),检出阳性群体471个,平均群体阳性率2.09%(95%CI:1.91%~2.28%);羊、牛、猪的个体阳性率分别为0.91%(95%CI:0.88%~0.94%)、0.24%(95%CI:0.21%~0.26%)、1.01%(95%CI:0.87%~1.17%),群体阳性率分别为2.48%(95%CI:2.25%~2.73%)、0.86%(95%CI:0.62%~1.15%)、1.96%(95%CI:1.16%~3.08%);全省14个市(州)的63个县(市、区)检出布病抗体阳性,检出阳性市州数量最多的是2020年和2021年,检出阳性县(市、区)数量最多的是2022年;2016年检出的阳性场点数最多,达89个,夏季6-8月份阳性检出数量最多;相对牛场和猪场,羊场的群体阳性率最高;交易市场的群体阳性率最高,其次是散户和商品代场。结果表明,湖南省近9年来家畜布病流行率持续较低,发生区域性大流行的风险较小,但流行范围较广,部分地区、部分种群和场点散发疫情风险较高,需要重点加强防范,应继续加强布病综合防控,加大调运监管力度,持续推进布病净化工作。In order to investigate the prevalence of livestock brucellosis in Hunan Province,relevant data about disease surveillance from 2014 to 2022 were downloaded from the database of“Disease Surveillance System of National Animal Health Monitoring Platform”for statistical analysis using SPSS software.The results revealed that 594180 serum samples from 22544 premises across the province were detected for antibodies against brucellosis,and a total of 4381 positive samples were detected,with an individual positive rate of 0.74%(95%CI:0.72%-0.76%),including 471 positive groups,with an average positive rate of 2.09%at group level(95%CI:1.91%-2.28%);the individual positive rates of sheep,cattle and pigs were 0.91%(95%CI:0.88%-0.94%),0.24%(95%CI:0.21%-0.26%)and 1.01%(95%CI:0.87%-1.17%),respectively,and the rates at group level were 2.48%(95%CI:2.25%-2.73%),0.86%(95%CI:0.62%-1.15%)and 1.96%(95%CI:1.16%-3.08%),respectively;positive antibodies were detected in 63 counties(cities/districts)under 14 cities(prefectures),the largest number of positive cities(prefectures)was detected in 2020 and 2021,that of positive counties(cities/districts)was in 2022,of positive premises was in 2016,which was up to 89,especially from June to August in summer;compared to cattle and swine farms,the positive rate at group level was highest in sheep farms;the population positive rate was highest in markets,followed by retail players and commercial agents.The results revealed that livestock brucellosis was prevalent in Hunan Province with a relatively low trend in the past 9 years,and the risk of regional pandemics was low.In view of the wide range of prevalence,as well as high risk of sporadic outbreaks in some regions,populations and premises,corresponding prevention measures should be strengthened.In conclusion,brucellosis should be comprehensively and continuously prevented,controlled and purified,and supervision for movement should be strengthened.
