    摘要:

    为了解山东省牛羊疫病的流行及免疫现状,汇总2020年山东省牛羊疫病报告数据以及监测数据等信息,分析牛羊疫病的时间分布、空间分布及病种分布;结合监测情况,分析牛羊疫病的免疫状况和暴发风险。2020年山东省牛病以新生犊牛腹泻、牛病毒性腹泻和牛传染性鼻气管炎为主,突发输入性牛结节性皮肤病,羊病以沙门氏菌病、绵羊疥癣和布鲁氏菌病为主;牛病主要集中在鲁北和鲁西北地区,羊病主要集中在鲁中、鲁西、鲁南及半岛北部地区;牛羊疫病有一定的时间分布特征,7—9月份牛病暴发较频繁,6—9月和12月羊病发病率较高;口蹄疫、小反刍兽疫免疫水平较高,整体暴发风险可控,但仍存在一定的牛羊口蹄疫非结构蛋白抗体阳性;布鲁氏菌病免疫水平偏低,感染抗体阳性群体内个体感染情况较严重,羊群感染程度高于牛群。分析提示:鲁北和鲁西北地区应重点加强新生犊牛腹泻、牛病毒性腹泻等牛病的防控,鲁中、鲁西、鲁南及半岛北部地区应加强沙门氏菌病、布鲁氏菌病等羊病的防控,继续推进牛羊布鲁氏菌病净化场(县)创建工作;对口蹄疫和小反刍兽疫等防控效果较好的疫病以及新传入的牛结节性皮肤病,应持续加强免疫和监测,防止疫情传入或复发。

    Abstract:

    In order to identify the prevalence and immune status of cattle and sheep diseases in Shandong Province,the data of reports and surveillance of cattle and sheep diseases in the province in 2020 were summarized,the distribution of the diseases was analyzed from the aspects of time,space and disease types,then the immune status and risk of outbreak were analyzed based on the situations under surveillance. It was concluded that major cattle diseases included diarrhea in newborn calves,bovine viral diarrhea,infectious bovine rhinotracheitis and emergent lumpy skin disease introduced from other regions,which were mainly distributed in northern and northwestern Shandong. For sheep diseases,salmonellosis,sheep scabies and brucellosis were prevalent in central,western and southern Shandong as well as northern peninsula;all the diseases were characterized by time distribution,cattle diseases frequently occurred during July to September,and sheep diseases occurred usually in June to September and December;the immune level against foot-and-mouth disease(FMD)and peste des petits ruminants(PPR)was higher,with controllable risk of outbreak in general,although certain non-structural protein antibody against FMD in cattle and sheep was positive;the level of immune against brucellosis was relatively low,individual infection in infected positive group was more serious,and the level of infection was higher in sheep compared to that in cattle. It was concluded that cattle diseases including diarrhea in newborn calves and bovine viral diarrhea should be controlled as a top priority in northern and northwestern Shandong,and control of sheep diseases including salmonellosis and brucellosis should be strengthened in central,western,southern and northern Shandong. The construction of purification farms(counties)for cattle and sheep brucellosis should be continued. For such diseases under better control as FMD and PPR as well as lumpy skin disease that was newly introduced,intensive vaccination and surveillance should be continued for the purpose of preventing any introduction or recurrence.
