Characterization and genomic analysis phage PmP19, a novel Proteus mirabilis phage with a broad host range
摘要
A lytic Proteus mirabilis phage, PmP19, was isolated from sewage on a farm. PmP19 has an icosahedral head (60 ± 3 nm in diameter) and a short tail (15 ± 2 nm long). Its genome, a linear, double-stranded DNA molecule 44,305 bp in length with an average GC content of 51.93%, has 52 putative open reading frames (ORFs). BLASTn comparisons and phylogenetic analysis revealed a close relationship between Pmp19 and Klebsiella phage vB_KpnP_ZK1. Bioinformatic analysis revealed that PmP19 belongs to the phage subfamily Molineuxvirinae.
