Advances in high-throughput sequencing (HTS) technologies and reductions in sequencing costs have revolutionised the study of genomics and molecular biology by making whole-genome sequencing (WGS) accessible to many laboratories. However, the analysis of WGS data requires significant computational effort, which is the major drawback in implementing WGS as a routine laboratory technique.
Automated pipelines have been developed to overcome this issue, but they do not exist for all organisms. This is the case for human respiratory syncytial virus (RSV), which is a leading cause of lower respiratory tract infections in infants, the elderly, and immunocompromised adults.
We present RSV-GenoScan, a fast and easy-to-use pipeline for WGS analysis of RSV generated by HTS on Illumina or Nanopore platforms. RSV-GenoScan automates the WGS analysis steps directly from the raw sequence data. The pipeline filters the sequence data, maps the reads to the RSV reference genomes, generates a consensus sequence, identifies the RSV subgroup, and lists amino acid mutations, insertions and deletions in the F and G viral genes. This enables the rapid identification of mutations in these coding genes that are known to confer resistance to monoclonal antibodies.

高通量测序(HTS)技术的进步和测序成本的降低使得全基因组测序(WGS)能够为许多实验室所接受,从而彻底改变了基因组学和分子生物学的研究。然而,WGS 数据的分析需要大量的计算工作,这是将 WGS 作为常规实验室技术实施的主要缺点。
已经开发了自动化管道来解决这个问题,但并不是所有的生物体都有。人类呼吸道合胞病毒(RSV)就是这种情况,它是婴儿、老年人和免疫功能低下的成年人下呼吸道感染的主要原因。
我们提出了 RSV-GenoScan,这是一种用于 Illumina 或 Nanopore 平台上 HTS 产生的 RSV 的 WGS 分析的快速易用的管道。RSV-GenoScan 直接从原始序列数据自动执行 WGS 分析步骤。该管道过滤序列数据,将读取映射到 RSV 参考基因组,生成一致序列,识别 RSV 亚群,并列出 F 和 G 病毒基因中的氨基酸突变、插入和缺失。这使得能够快速识别这些编码基因中的突变,这些突变已知会导致对单克隆抗体的耐药性。
