The morphology and antigenic properties of 34 phages of Vibrio parahaemolyticus and V. alginolyticus strains isolated from Black Sea water, as well as their range of lytic activity and specificity of action, have been studied. Most of these phages have been found to lyze both V. parahaemolyticus and V. alginolyticus strains. In addition, highly specific phages capable of lyzing only V. parahaemolyticus serotype O5:K15, have been detected. The latter fact is a precedent indicating the possibility of search for other typing phages and the development of the scheme for the phage typing of V. parahaemolyticus in future.

In this study, a lytic phage, named PG216, was obtained from seawater collected in Qingdao, using Vibrio parahaemolyticus strain G299 as its host. Transmission electron microscopy revealed that phage PG216 has an icosahedral head with a diameter of 100 ± 6.7 nm and a contractible tail with a length of 126 ± 6.

Article Synopsis
- Non-inheritable antibiotic resistance allows bacteria to survive treatment, with exogenous factors like high magnesium playing a significant role.
- Functional metabolomics show that magnesium affects fatty acid biosynthesis, leading to altered bacterial response to antibiotics based on the balance of saturated and unsaturated fatty acids.
- Lipid metabolism changes due to magnesium, specifically in glycerophospholipid pathways, enhance bacterial membrane properties that reduce antibiotic uptake and increase resistance.

Vibrio-induced diseases pose a significant threat to shrimp aquaculture. While the mechanisms underlying Vibrio penetration of shrimp shells and the gastrointestinal tract remain unclear, this study implicates chitinases as critical virulence factors. Despite their inability to utilize chitin or shrimp shells as sole carbon and nitrogen sources, three major shrimp pathogens-V.

Crustins are a family of antimicrobial peptides (AMPs) that play a pivotal role in the innate immune system of crustaceans. The discovery of novel AMPs from natural sources is crucial for expanding our current database of these peptides. Here, we identified and characterized a novel member of the crustin family, named Crus-SWD1, derived from .
