The application discloses a lytic
bacteriophage vB_VpaS_R40Z and application thereof in preventing and controlling
Vibrio parahaemolyticus in
aquaculture environment. The
Vibrio parahaemolyticus
bacteriophage vB_VpaS_R40Z has a preservation number of GDMCC No: 67440-B1. The R40Z can lyse multiple strains of
Vibrio parahaemolyticus and
Vibrio alginolyticus, and has the ability to adapt to the
aquaculture environment, and remains
high activity within the range of 4-25 DEG C and pH 4-10;
genome analysis does not detect
virulence genes or
drug resistance genes; phylogenetic comparison with the whole
genome shows that the similarity of R40Z with the related
bacteriophage is lower than the
species level threshold, and R40Z is a new bacteriophage species; R40Z can significantly inhibit the growth of the host under multiple infection multiplicities. R40Z has the advantages of strong lytic ability, good
environmental stability, high
genome safety and unique evolutionary characteristics, and is a
water product vibrio disease biological prevention and control bacteriophage with application potential.
