2013—2016年宁海县畜禽重大传染病免疫状况监测分析

Monitor and analysis on immune status of major infectious diseases of livestock and poultry in Ninghai County from 2013 to 2016

为监测2013—2016年浙江省宁海县畜禽重大传染病免疫状况,按照国家推荐的标准诊断方法对宁海县养殖的猪、牛、羊、鸡、鸭进行重大传染病抗体检测。检测结果显示,2013—2016年宁海县畜禽免疫状况整体良好。这4年:猪O型口蹄疫、猪瘟和猪繁殖与呼吸综合征抗体年均阳性率分别为76.27%、75.84%和79.88%;牛O型、A型和亚Ⅰ型口蹄疫病毒抗体阳性率均>90%;羊O型、亚Ⅰ型口蹄疫抗体年均阳性率分别是65.37%、67.52%,须加强免疫;家禽(鸡和鸭)H7N9亚型禽流感抗体阳性率为0,鸡、鸭的H5N1亚型禽流感抗体年均阳性率分别为98.67%、95.60%;鸡新城疫抗体年均阳性率为62.86%,受季节影响较大,夏季抗体阳性率最低(季平均54.64%),仍须加强免疫。本研究获得的2013—2016年宁海县重大传染病的免疫效果可为国家强制性免疫计划的制定和效果评估提供基础数据。

The aim of this study was to monitor the immune status of major infectious diseases of livestock and poultry in Ninghai County from 2013 to 2016.The antibodies of swine,bovine,sheep,chicken and duck were determined according to the national standards.The testing results showed that the overall immune status of livestock and poultry in Ninghai County was good from 2013 to 2016.The average annual positive rates of foot and mouth disease(FMD)type O,classical swine fever and porcine reproductive and respiratory syndrome antibodies in swine were 76.27%,75.84%and 79.88%,respectively.The positive rates of FMD types O,A and Asia I antibodies in bovine were all above 90%.The average annual positive rates of FMD types O and Asia I antibodies in goat were 65.37%and 67.52%,respectively,and the immunization needs to be strengthened.The positive rate of H7N9 antibodies in poultry(chicken and duck)were 0.The average annual positive rates of H5N1 in chicken and duck were 98.67%and 95.60%,respectively.The average annual positive rate of Newcastle disease(ND)antibody was 62.86%,which was affected by season.In summer,the positive rate of ND was the lowest(quarter average 54.64%).It still needs to strengthen the immunity of ND.This study has summarized the immunity effects of the major infectious diseases in Ninghai County from 2013 to 2016,which could provide the basic data for the formulation and evaluation of the compulsory immunization program in China.
