目的探讨流行性喘憋性肺炎（简称流喘肺炎）与散发肺炎呼吸道合胞病毒（ＲＳＶ）分离株Ｆ蛋白的异同。方法采用ＰＣＲ片段直接测序及克隆测序，对１１株流喘肺炎ＲＳＶ分离株及５株散发肺炎ＲＳＶ分离株Ｆ蛋白基因序列进行了分析比较。结果被检测流喘肺炎ＲＳＶ分离株中，３６％（４／１１）的毒株其Ｆ蛋白基因３′非编码区（３′ＮＣＲ）（第１７４１位核苷酸）存在６个核苷酸插入，而散发肺炎ＲＳＶ分离株均无此插入存在。结论ＲＳＶ流喘肺炎分离株与散发肺炎分离株Ｆ蛋白基因的３′ＮＣＲ有差异。
Objective To explore the similarities and differences between Fusarium pneumoniae pneumonia and respiratory syncytial virus (RSV) isolates. Methods The sequence of F protein gene of 11 isolates of RSV pneumonia and 5 isolates of RSV isolates from pneumonia were analyzed by direct sequencing and cloning sequencing of PCR fragments. Results 36% (4/11) of the RSV isolates of asthmatic pneumonia were found to have 6 nucleotides in the 3 ’non-coding region (3’-NCR) of the F protein gene (nucleotide 1741) Insertion, and pneumococcal RSV isolates were present without this insertion. Conclusion There is a difference in 3’NCR between RSV influenza pneumonia isolates and F protein gene of pneumococcal isolates.
