我国部分地区呼吸道合胞病毒分离株的亚型鉴定

A survery of subgroup of isolated respiratory syncytial virus in China

为了解我国部分地区呼吸道合胞病毒（ＲＳＶ）的亚型分布情况，采用单克隆抗体和免疫荧光技术，对近年来从北京、广州、南京、长春、和ＲＳＶ感染爆发流行的津冀地区分离出的共１００株ＲＳＶ进行了亚型鉴定。结果：其中９７株为Ａ亚型，３株为Ｂ亚型。提示：近年来这些地区无论是南方还是北方流行的ＲＳＶ主要为Ａ亚型；津冀地区流行性喘憋性肺炎的爆发流行也与Ａ亚型有关。

To investigate the subgroup of respiratory syncytial virus (RSV) in China, the authors determined the subgroup of 100 strains of RSV isolated recently from different areas of China by using monoclonal antibodies. ninty seven out of 100 strains were of subgroup A and 3 were of subgroup B. The results suggested that subgroup A was currently dominant in the northern and southern parts of China. The prevalence of epidemic asthmatic pneumonia was also associated with subgroup A RSV infection.
