Abstract

Aim: The study aimed to analyze human respiratory syncytial virus (hRSV) strains in nasopharyngeal aspirates obtained retrospectively. Materials & methods: Clinical information of ARI patients (n = 53) was accessed and 2nd hypervariable region of G protein gene of RSV was sequenced and analyzed. Results: Cough (98.1%), fever 40 (75.4%) and shortness of breath 32 (60.3%) were the common symptom. Sequence determination (n = 45) categorized all the strains in ON1 genotype. Potential O- and N- glycosylation were observed at some sites and purifying selections were observed at 274 and 320 codon positions. Conclusion: The study reports replacement of other RSVA genotypes with ON1. The future course of studies should emphasize on clinical implications of presence of hRSVA-ON1 genotype in a given population.

沙特阿拉伯利雅得 2019-2020 年冬季唯一出现的人类 RSVA-ON1 基因型：一项回顾性研究

目的：本研究旨在分析回顾性获取的鼻咽抽吸物中的人类呼吸道合胞病毒（hRSV）毒株。材料与方法获取 ARI 患者（53 人）的临床信息，并对 RSV G 蛋白基因的第 2 个高变异区进行测序和分析。结果咳嗽（98.1%）、发烧 40 例（75.4%）和呼吸急促 32 例（60.3%）是常见症状。序列测定（n = 45）将所有菌株归为 ON1 基因型。在一些位点观察到潜在的 O- 和 N- 糖基化，在 274 和 320 个密码子位置观察到纯化选择。结论该研究报告了用 ON1 取代其他 RSVA 基因型的情况。今后的研究应强调特定人群中出现 hRSVA-ON1 基因型的临床意义。
