ABSTRACT
Vibrio alginolyticus is a common foodborne pathogen existing both in contaminated seafood and the environment and can cause serious mortality in aquaculture facilities. Bacteriophages can be used as an alternative bio-control agent to eliminate and reduce pathogens. In this study, a novel lytic phage, designated vB_ValP_VA-RY-3 (referred to as S1R3Y), was isolated from sewage collected in Dalian, China. The linear double-stranded DNA genome of phage S1R3Y is 40.271 kb, which has a mol% G + C content of 43.98, containing 51 ORFs with a T7-like genomic organization. It shared the closest relationship with phage vB_CsaP_Ss1, but the homology coverage is just 6%. S1R3Y lacks tRNA and no known virulence or lysogenic genes were found. S1R3Y had a burst size of 147 PFU/cell and is stable under different temperatures (4-56 °C) and pH (5.0-7.0). A comparison of its genomic features and phylogenetic analysis revealed that phage S1R3Y is a novel member of the order Caudovirales, family Podoviridae. Our results suggest that phage S1R3Y may represent a potential therapeutic agent against Vibrio alginolyticus.
