【摘要】 本文报告了从1984年9月至1985年6月在成都地区按季节共收集猪血清731份,并监测甲、乙型流感病毒抗体的分布情况,用血凝抑制试验测得乙型流感抗体阳性56份,不同季节阳性率在 0～11.6％之间,并用单扩溶血试验复核已测得血抑抗体阳性的猪血清,获双阳性率为48.6％,进一步印证了猪是乙型流感病毒贮存宿主。更多还原

【Abstract】 Seven hundred thirty one swine serumspecimens were collected at 2 to 3 monthintervals 5 times from September 1984 toJune 1985. Antibodies to influenza viruseswere detected by hemagglutination inhibi-tion test （HI）, current strains of influenzaB, new A₁（H₁N₁）, A₃（H₃N₂） virus beingused as antigens of HI. Positive specimensof swine serum antibodies were detectedagain by single radial hemolysis （SRH） testfor surveillance of distribution of antibodiesin different seasons. The results showedthat HI antibodies to influenza B virus werefound in 56 of 731 swine sera, with a po-sitive rate of 7.7%. Antibodies to influenzaB virus were found in serum specimensfrom November to the next June, with thepositive rate of the antibodies ranging from5.4% to 11.6%. The double positive ratewas 48.6% when positive specimens of HIwere detected again by SRH. The results of the surveillance for serahave mirrored again the fact that swinecan be infected naturally by influenza Bvirus, and theoretically provided moreample evidence that swine can be a reser-voir of human influenza B, and verifiedthat the positive rates of antibodies to thecurrent human strains of influenza A （HN₁）and （H₃N₂） in the swine population weresimilar to those in the human population.
