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。
In order to understand the subtype distribution of respiratory syncytial virus (RSV) in some areas in China, monoclonal antibodies and immunofluorescence techniques were used to separate the RSV infections in recent years from Tianjin, Hebei, Guangzhou, Nanjing, Changchun and the outbreak of RSV A total of 100 RSV subtypes were identified. Results: 97 were A subtype and 3 subtype B subtype. It is suggested that the RSV prevalence in these areas in both southern and northern China in recent years is mainly A subtypes. The outbreak of epidemic pneumonia in Tianjin and Hebei is also related to subtypes A.
