A novel Vibrio parahaemolyticus phage, designated vB_VpaM_PVP-XSN (hereafter referred to as PVP-XSN), was isolated from costal soil. PVP-XSN has a polyhedral head (54.1 ± 11.1 nm in diameter) and a long contractile tail (110.5 ± 3.2 nm in length). The phage exhibits rapid adsorption and has a burst size of 167 plaque-forming units (PFU) per cell. Furthermore, PVP-XSN shows tolerance to temperatures ranging from 20°C to 50°C and pH levels between 5 and 11. Its linear double-stranded DNA genome is 45,651 base pairs in length and contains 66 putative open reading frames (ORFs). Comparative genomic analysis suggests that PVP-XSN represents a new genus of viruses.
从沿海土壤中分离出一种新型副溶血性弧菌噬菌体，命名为vB_VpaM_PVP-XSN（以下简称PVP-XSN）。PVP-XSN具有多面体头部（直径54.1±11.1纳米）和长收缩尾（长度110.5±3.2纳米）。该噬菌体表现出快速吸附，每个细胞的爆发量为167个噬菌斑形成单位（PFU）。此外，PVP-XSN对20°C至50°C的温度和5至11的pH水平具有耐受性。其线性双链DNA基因组长度为45,651个碱基对，包含66个推定的开放阅读框（ORF）。比较基因组分析表明，PVP-XSN代表一种新的病毒属。
