RSV complement fixation antibodies were established in 200 paired maternal and cord blood sera. Geometric mean titres in cord sera were significantly higher than in matermal sera. The differences did not depend on the virus strain used. Half of the paired sera (taken at random) were also submitted to microneutralization tests. No differences were found between geometric mean titres in maternal and cord sera.
在200对母婴血清中检测了呼吸道合胞病毒补体结合抗体。脐血血清中的几何平均滴度显著高于母血血清。这些差异并不取决于所使用的病毒株。随机选取一半的配对血清进行微量中和试验。母血和脐血血清的几何平均滴度之间未发现差异。
