北京地区婴幼儿病毒性肺炎血清抗体调查

本文对1978年冬~1988年春诊断为婴幼儿肺炎住院病人171份双份血清,采用血凝抑制试验及免疫酶联检测方法,进行腺病毒抗体检测。结果S₂≥S₁₄倍升高者56份,阳性率为32.75%,以3、7两型腺病毒为主;对6个冬春129份双份血清进行流感、副流感病毒抗体检测,结果S₂≥S₁₄倍升高者11例,阳性率为8.53%,以甲₁和甲₃型为主;行副流感病毒抗体检测结果,S₂≥S₁₄倍升高者27份,阳性率为20.93%,型别以副Ⅲ居多;对4个冬春60份双份血清行RSV抗体检测,结果阳性者14份,阳性率为23.30%。

Serological Investigation on Infant Virus Pneumonia in Beijing

Antibody against adenovirus in paired sera of 171 cases of infant virus pneumonia observed in 7 winter-spring periods was assayed by hemagglutination-inhibition test and enzyme-linked immunosorbent assay. A 4-fold or greater rise in the titer was found in 56 cases (32.75%). Type 3 and Type 7 were predominant. Antibody against influenza virus was assayed in paired sera of 129 cases in 6 winter-spring periods. A 4-fold or greater increase in the titer was observed in 11 cases (8.53%), with predominance of A1 and A3. Antibody against parainfluenza virus was also assayed in paired sera of these 129 cases. A 4-fold or more rise in the titer was demonstrated in 27 cases (20.93%), with predominance of Type 3. Antibody against respiratory syncytial virus was assayed in paired sera of 60 cases. A 4-fold or greater increase in the titer was shown in 14 cases (23.30%).
