Vibrio phage vB_VpaP_SJSY21 Genome sequencing and assembly. Vibrio phage vB_VpaP_SJSY21

A novel Vibrio parahaemolyticus phage was isolated from sewage sample and named vB_VpaP_SJSY21. The biological and genomic properties of phage SJSY21 was characterized and its effect on the intestinal microbial community of L. vannamei was analyzed. The main objectives of the present study were (1) to isolate and characterize this novel V. parahaemolyticus phage SJSY21, (2) to explore the preventive effect of phage SJSY21 in the culture of L. vannamei, and (3) to develop a safer treatment method for targeted eliminating Vibrio controlling AHPND and provide new methods for the further study of phage treatment in the aquatic field.
