Complete genome sequence of virulent bacteriophage SHOU24, which infects foodborne pathogenic Vibrio parahaemolyticus

摘要

A novel lytic Vibrio parahaemolyticus phage (SHOU24) belonging to the family Siphoviridae was isolated from aquatic market sewage. The phage is only able to infect V. parahaemolyticus containing a tdh gene. SHOU24 has a linear genome of 77,837 bp with a G+C content of 46.0 %. In total, 88 predicted proteins have homologues in databases, and the majority of the core genes share high sequence similarity with genes from unrelated viruses and bacteria. Genes related to lysogeny and host lysis were not detected. However, the detection method, the results of a one-step growth experiment and analysis using the Phage Classification Tool Set (PHACTS) indicate that SHOU24 is lytic. A bioinformatics analysis showed that SHOU24 is not closely related to other Vibrio phages.
