摘　　要：目的以血清学方法证实2004年江苏省苏北地区中小学生腺病毒3型急性呼吸道感染的暴发流行。方法应用酶联免疫吸附法(ELISA)检测患者急性期IgM抗体、恢复期IgG抗体;应用中和试验方法检测患者急性期、恢复期血清和未患病学生对照血清的中和抗体,并应用SPSS11.0软件对试验数据进行统计分析。结果患者急性期IgM抗体阳性率为3.7%,恢复期IgG抗体阳性率为44.4%,恢复期中和抗体阳性率为59.5%;未患病学生分别为0%、8.3%和33.3%,卡方检验P值分别为0.510、0.018、0.226;9例患者配对双份血清中有6例患者恢复期血清中和抗体保护作用均较急性期血清明显增长;ELISA方法检测IgG与中和试验检测中和抗体的一致率为61.4%,Kappa检验P=0.070。结论血清学方法进一步证实苏北地区急性呼吸道感染暴发流行的病原体为腺病毒3型。Objective To finally diagnose the outbreak of acute respiratory infection caused by Adenovirus 3 in students of the north of Jiangsu province by serologic study. Methods An enzymelinked immunosorbent assay （ELISA） has been used to detect the adenovirus IgM in the serum of acute phase and the adenovirus IgG in the serum of recovery phase. A neutralization test has been used to detect the neutralization antibody in the serum of acute and recovery phase from cases and in the serum from the control. The SPSS11.0 has been applied to the statistical analysis of the data. Results The positive rate of IgM, IgG and recovery phase neutralization antibody of cases are 3.7%, 44.4% and 59.5% respectively, while those of control are 0%, 8.3% and 33.3% respectively, and the P values of Chi Square are 0. 510, 0. 018 and 0,226 respectively. The neutralization test of paired serum of 6 in 9 cases showed that the antibody titers was obviously increased. The concordance between IgG detected by ELISA and neutralization antibody detected by neutralization test is 61.4% and the P value of Kappa is 0. 070. Conclusion By the serologic study, we can finally diagnose that the outbreak of acute respiratory infection was caused by Adenovirus 3.
