摘　　要：Vibrio harveyi is a Gram-negative,rod-shaped,polar flagellate,facultatively anaerobic,halophilic,bioluminescent marine bacteria that belongs to the family of Vibrionaceae,class,Gammaproteobacteria.This pathogenic organism is responsible for various diseases of vertebrates and invertebrates in marine habitats,including shrimp aquaculture.Various symptoms like lesions,gastroenteritis,skin ulcers,eye lesions,and tail rot have been observed due to V.harveyi infection.The pathogenic-ity mechanism of V.harveyi involves endotoxin lipopolysaccharide,extracellular proteases,and bacteriophage interaction.Hemolysin genes encoded extracellular hemolysin-like phospholipase B toxin could inactivate fish species via the caspase inactivation pathway,ultimately leading to apoptosis.In addition,VBNC(viable but nonculturable)cells are another basis of vibriosis outbreaks in the shrimp aquaculture sector.The extensive amount of antibiotic use promotes the generation of multidrug-resistant strains.Therefore,as an alternative strategy to combat V.harveyi infection,bacteriophages are utilized as a biocontrol agent.However,there is a lack of research on the immobilization and development of encapsulation strategies of V.harveyi-infecting bacteriophages which need to be studied further.In conclusion,the pathogenicity of V.harveyi and its biocontrol by bacteriophages has been documented in this review.
