The Vibrio infection resistance, and phenotypic characteristics of shrimp after cross-transplantation of bacterial consortia enriched from WES and BFS shrimp. a Schematic diagram of the experimental procedure. The bacterial consortia were obtained from the shrimp cultured in the WES and BFS for 21 days, and the bacterial consortia were cross-transplanted to WES and BFS shrimp. After 36 h of cross-transplantation, the shrimp that received PBS and bacterial consortia were infected by the pathogenic Vibrio parahaemolyticus. b The effects of cross-transplantation on the shrimp survival curves after infection. c Phenotypic characteristics of shrimp after infection. Black, white, and red arrows indicate the stomach, hepatopancreas, and gut of shrimp in (c), respectively. Bar = 1 cm in (c).
