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 To understand the antibody level of Japanese encephalitis in the population of Baoshan City and the antibody status of the main source of infection in pigs, and to infer the population vaccination effect and the status of Japanese encephalitis in pigs, so as to provide evidence for the scientific prevention of Japanese encephalitis. Methods ELISA and ELISA were used to detect the pig serum and human serum samples. The data were analyzed by SPSS 13.0. Results 351 serum samples from healthy people were collected from 5 counties and cities in Baoshan City, 349 positive IgG antibodies were detected, the positive rate was 99.43%. There was significant difference between different age groups (χ ~ 2 = 15.21, P <0.01 ). 240 samples of pig serum were collected in Longyang District, 222 were positive for antibody test, the positive rate was 92.50%. The difference was statistically significant (χ ~ 2 = 32.57, P <0.01). Conclusion The population of Baoshan has good immune response to Japanese encephalitis, but the infection rate of pigs is higher. Should continue to strengthen the vaccination-based comprehensive prevention and control measures to control the incidence of JE and reduce the risk.
