Synergistic Effects of Shewanella algae A3 and Serratia marcescens Van80 UB3 on Immune Response, Gene Expression and Resistance to Vibrio parahaemolyticus Vp5 in Pacific White Shrimp

Key Points

• The aim is to explore how the combination of Shewanella algae and Serratia marcescens affects shrimp health and resistance to Vibrio parahaemolyticus.
• Conducted randomized trial on Pacific White Shrimp with administration of Shewanella algae A3 and Serratia marcescens Van80 UB3.
• Evaluated immune response, gene expression changes, and resistance to Vibrio parahaemolyticus Vp5.
• Measured health improvements and resistance levels through cfu/g of feed.
• Treatment significantly enhances immune response and gene expression related to resistance.
• Shrimp exposed to the bacteria show improved resistance to Vibrio parahaemolyticus compared to control groups.
