摘要 目的了解保山市人群乙型脑炎抗体水平和主要传染源猪的抗体状态,推断人群疫苗接种效果和猪的乙脑感染状况,为科学防制乙脑提供依据。方法采用ELISA方法对采集的猪血清和人血清标本进行实验室检测,利用SPSS13.0建立数据库对数据进行统计学分析。结果在保山市5个县市区采集健康人血清标本351份,检测Ig G抗体阳性349份,阳性率99.43%,不同年龄组之间差异有统计学意义(χ^2=15.21,P﹤0.01)。在隆阳区采集猪血清标本240份,抗体检测阳性222份,阳性率92.50%,不同采集地差异有统计学意义(χ^2=32.57,P﹤0.01)。结论保山市人群乙脑免疫效果好,但猪感染率较高。应继续加强以疫苗接种为主的综合性防控措施,以控制乙脑发病,降低危害。 Objective Objective To understand the antibody levels of Japanese encephalitis among crowd and the pigs in Baos- han City, to infer the crowd vaccination effect and pig infection status, and provide the evidences for scientific preven- tion. Methods The pig and human serum samp|es were tested by using ELISA, and the data was analyzed by SPSS 13.0. Results A total of 351 healthy human serum samples were collected in five counties, the IgG antibody positive were 349, the positive rate was 99.43%, and the statistical difference was observed among age groups(χ^2= 15.21, P 〈 0. 01 ). In the case of pig serum samples of 240 in Longyang District, antibody positive were 222, the positive rate was 92.50%, the statistical significant differences were also observed among different study places(χ^2= 32. 57, P 〈 0. 01 ). Conclusion The immuni- zation effect among crowd is good in Baoshan City, and the pig infection rate is higher, comprehensive prevention and control measures based on vaccination should be continued to strengthen to reduce the hazards.
