Isolation and genome-wide analysis of new Acinetobacter baumannii bacteriophage vB_AbaM_AB3P2

Abstract

Abstract New lytic Acinetobacter baumannii phage, vB_AbaM_AB3P2, was isolated from sewage treatment plant of Luoyang, China. The genome of vB_AbaM_AB3P2 is composed of double-strand DNA that is 44,824bp in length with G + C content of 37.75%. 96 open reading frames were identified, genes for antibiotic resistance and virulence factors were not found. The genomic and phylogenetic analyses of this phage revealed that it represents a new species in genus Obolenskvirus. Phage vB_AbaM_AB3P2, which has short latent period (10 min) and high stability in 30–70 ◦C and pH 2–10, is potentially useful for controlling multi-drug resistant A. baumannii in the future.
