Vibrio diabolicus is widely distributed in the marine environment and is an important pathogen of aquatic organisms such as shrimp, fish, and mollusks. The emergence of multi-drug resistance among these bacteria has resulted in a global public health problem, which requires alternative treatment approaches, such as phage therapy. In the present study, we isolated the phage vB_Vc_SrVc2 from the hepatopancreas of white shrimp showing symptoms of acute hepatopancreatic necrosis disease (AHPND) and evaluated the efficacy of this phage in preventing the mortality associated with V.

These phages, designated vB_Sal_EH1, vB_Sal_EH2, vB_Sal_EH3, vB_Sal_EH4, and vB_Sal_EH7, were characterized, and their genomes were sequenced. Phylogenetic analysis showed that they grouped within the genus Epseptimavirus, with genome sizes ranging from 108,554 to 115,218 bp.

- The study tested the protective effects of a phage cocktail on Pacific white shrimp postlarvae, which were chosen for their ability to target various pathogenic Vibrio species.
- Both culture-dependent and independent methods showed a significant reduction in Vibrio species levels after treatment with the phage cocktail.
- Treated shrimp displayed less tissue damage and increased lipid accumulation, suggesting that phage therapy is an effective and environmentally safe alternative to antibiotics in shrimp farming.
