Summary: Vaccines are safe and effective in controlling bacterial diseases in the aquaculture industry and align with green farming. A novel approach of preparing live-attenuated V. alginolyticus vaccine using high magnesium concentration to attenuate virulence was developed. Metabolomic analysis revealed enhanced TCA cycle and increased fumarate as crucial pathways and biomarkers in vaccine-mediated and survival fish.

Summary: In this study, RNA-seq analysis of Pacific oyster gill tissue was performed to investigate the immune response to bacterial infection. The results showed that the immune strategy of the oyster changed significantly at short-term and long-term stages, with activation of immune-related genes with different functions. This work provides valuable insights into immune response, disease monitoring, and disease resistance breeding.

Summary: In this study, a filamentous phage called Vaf1 was isolated and characterized from the marine pathogen Vibrio alginolyticus AP-1. The presence of phage Vaf1 was found to significantly increase biofilm formation, swarming motility, and contact-dependent competition. Additionally, the Vaf1 phage was found to contribute to the virulence of V. alginolyticus in zebrafish.

Summary: The study evaluated the effectiveness of the Delta dctP strain as a live-attenuated vaccine against vibriosis caused by Vibrio alginolyticus in pearl gentian grouper. The results showed that the vaccine significantly improved the survival rate of the fish and enhanced the immune response by upregulating immune-related genes and increasing the levels of specific antibodies and immune enzymes in the serum.

Summary: This study investigates the synergistic effect of low salinity stress and pathogen infection on the mortality of Pacific oysters. The results show that low salinity stress affects microbial composition and immune response of infected oysters, suggesting that it may trigger immune dysregulation and contribute to oyster mass mortality.

Summary: This study investigated the expression patterns of Two-component system (TCS) genes in V. parahaemolyticus-infected THP-1 cell-derived macrophages at the early stage. Several critical TCS genes that may regulate V. parahaemolyticus in macrophages were identified through protein-protein interaction network analysis. Additionally, potential immune escape pathways of V. parahaemolyticus in macrophages were explored using RNA-seq.

Summary: In this study, a transcriptome analysis was conducted on Pacific oysters infected with Vibrio alginolyticus, revealing differentially expressed genes (DEGs) related to immunity. A protein-protein interaction network was constructed to investigate the immune defense mechanism of the oyster. Key genes involved in immune-related signaling pathways were screened and validated. This research provides insights for addressing the problem of high mortality in oyster farming during summer and offers references for the future development of disease-resistant oysters.

Summary: In this study, a new Vibrio phage vB_ValM_PVA8 (PVA8) was isolated from sewage water and found to efficiently infect pathogenic Vibrio species. The phage belonged to the Straboviridae family and had a 246,348-bp double-stranded DNA genome with 388 putative open reading frames (ORFs). It exhibited stable characteristics over a broad pH range and a wide temperature span, and showed strong multiplication capacity against V. alginolyticus. The results indicate that PVA8 has the potential to be a promising biological agent for Vibrio control in aquaculture farming industry.
