Abstract

We report the complete genome sequences of four parechovirus-A3 (PeV-A3) isolates from Children's Mercy Kansas City (CMKC), United States of America (USA): PeV-A3-MO-12-CMKC/CSF/MO/USA/2012 (isolated in 2012 from cerebrospinal fluid), PeV-A3-8C-CMKC/CSF/MO/USA/2022/ (isolated in 2022 from cerebrospinal fluid), PeV-A3-9C-CMKC/CSF/MO/USA/2022 (isolated in 2022 from cerebrospinal fluid), and PeV-A3-11B-CMKC/Blood/MO/USA/2022 (isolated in 2022 from blood). Sequence analysis revealed multiple mutations throughout the genome of the PeV-A3 isolates in comparison to the prototypic PeV-A3 A308/99 reference sequence (AB084913). Several unique amino acid changes were observed in the PeV-A3 isolates from 2022 that were absent in the PeV-A3 isolate from 2012. Phylogenetic analysis comparison determined that the sequenced PeV-A3 isolates from 2022 cluster together as a separate clade.

摘要

我们报告了来自美国堪萨斯城儿童慈善医院(CMKC)的4株A3型细小病毒(PeV-A3)分离株的全基因组序列:PeV-A3-MO-12-CMKC/CSF/MO/USA/2012(于2012年从脑脊液中分离)、PeV-A3-8C-CMKC/CSF/MO/USA/2022/(于2022年从脑脊液中分离)、PeV-A3-9C-CMKC/CSF/MO/USA/2022(于2022年从脑脊液中分离)以及PeV-A3-11B-CMKC/Blood/MO/USA/2022(于2022年从血液中分离)。序列分析显示,与原型PeV-A3 A308/99参考序列(AB084913)相比,PeV-A3分离株的全基因组存在多个突变。在2022年的PeV-A3分离株中观察到了一些独特的氨基酸变化,而这些变化在2012年的PeV-A3分离株中不存在。系统发育分析比较确定,2022年测序的PeV-A3分离株聚集在一起形成一个单独的分支。
