养殖与饲料2024年第2期17河南省牛羊规模场布鲁氏菌病感染情况调查赵胜杰1，盛敏1，仲伟平2*1.河南省动物疫病预防控制中心,郑州450000；2.河南省开封市动物疫病预防控制中心，河南开封475000摘要【目的］掌握河南省牛羊布鲁氏菌病流行情况，为牛羊布病防控和净化工作提供理论和科学依据。方法12022年对河南省168个场次的4902头牛羊血清样品进行布病感染抗体检测，并按动物种类、场点类别等对检测结果进行统计分析。［结果2022年河南省牛羊布病感染抗体平均场群阳性率为5.36%，平均个体阳性率为0.47%；牛布病感染抗体场群阳性率为3.61%，个体阳性率为0.24%；羊场群阳性率为7.06%，个体阳性率为0.71%；阳性样品均来自商品代养殖场（户），种畜场、屠宰场无阳性样品检出。［结论]河南省牛羊布病流行情况整体处于可控水平，种畜场布病净化工作取得了一定成效，随着牛羊养殖规模化程度的提升，当前牛羊布病防控的重点在于商品代规模场（户），应依据调查结果，结合场群实际，进一步完善和推进布病净化工作。关键词牛羊；布鲁氏菌病；感染抗体；调查；布病防控；规模化养殖InvestigationonBrucellosisinfectioninthecattleandsheepfarmswithlargescaleinHenanProvinceZHAOShengjie',SHENGMin',ZHONGWeiping*1.HenanProvincialCenterforAnimalDiseasePreventionandControl,Zhengzhou450000,China;2.AnimalDiseasePreventionandControlCenterofKaifengCity,HenanProvince,Kaifeng475000,ChinaAbstract[Objectives]TheepidemicsituationofBrucellosisincattleandsheepinHenanProv-incewasinvestigatedtoprovidethetheoreticalandscientificbasisforthepreventionandcontrolofBrucellosis,andpurificationincattleandsheepfarms.[Methods]4902serumsamplesofcattleandsheepfrom168herdsinHenanProvinceweredetectedforantibodiesagainstBrucellosisin2022.Theresultsofdetectionwerestatisticallyanalyzedbasedonthespeciesofanimals,thetypesoffarms,etc.[Results]TheresultsshowedthattheaveragepositiverateofantibodiesagainstBrucellosi-sinthecattleandsheepinHenanProvincein2022atherdlevelandattheindividuallevelwas5.36%and0.47%.ThepositiverateofantibodiesagainstBrucellosisincattleatherdlevelandattheindividuallevelwas3.61%and0.24%.ThepositiverateofantibodiesagainstBrucellosisinsheepat收稿日期：2023-08-29作者简介：赵胜杰，男，198...
