Genome sequences of human rhinoviruses (HRV) have primarily been from stocks collected in the 1960s, with genomes and phylogeny of modern HRVs remaining undefined. Here, two modern isolates (hrv-A101 and hrv-A101-v1) collected approximately 8 years apart were sequenced in their entirety. Incorporation into our full-genome HRV alignment with subsequent phylogenetic network inference indicated that these represent a unique HRV-A, localized within a distinct divergent clade. They appear to have resulted from recombination of the hrv-65 and hrv-78 lineages. These results support our contention that there are unrecognized distinct HRV-A strains, and that recombination is evident in currently circulating strains.
人类鼻病毒(HRV)的基因组序列主要来自 20 世纪 60 年代采集的病毒株,而现代 HRV 的基因组和系统发育仍然尚未明确。在这里,我们对大约相隔 8 年收集的两个现代分离株(hrv-A101 和 hrv-A101-v1)进行了全基因组测序。将它们整合到我们的全基因组 HRV 序列比对中,并进行随后的系统发育网络推断,表明它们代表了一个独特的 HRV-A 株,位于一个独特的分支中。它们似乎是由 hrv-65 和 hrv-78 两个谱系重组而来。这些结果支持我们的观点,即存在未被识别的独特 HRV-A 株,重组在当前流行的株系中很明显。
