Genomic analysis of Acinetobacter phage BUCT629, a newly isolated member of the genus Obolenskvirus

Abstract

A new virulent Acinetobacter phage, BUCT629 (GenBank no. MZ712044.1), was isolated from hospital sewage. Next-generation sequencing (NGS) results demonstrated that the double-stranded linear DNA genome of phage BUCT629 is 46,325 bp in length with a G+C content of 38%. The BLASTn analysis showed that the genome sequence shared similarity with Acinetobacter phage vB_AbaM_IME285, with 65% query coverage and 98.23% identity, suggesting that phage BUCT629 is a novel phage. The phage genome contains 89 putative protein-coding genes, and no rRNA or tRNA genes were identified. The results of this study may be helpful for discovering new antibacterial agents and for understanding the evolution and genetic diversity of Acinetobacter phages.
