Pathogenic Characteristics of Shrimp Early Mortality Syndrome (EMS)-Causing Vibrio parahaemolyticus: A Comparative Transcriptomic Study Suggests the Relationship Between Metabolic Fitness and Virulence Gene Expression.

ABSTRACT: Vibrio parahaemolyticus (VP) is a major bacterial species that causes early mortality syndrome (EMS) in shrimps. EMS can be classified into two groups based on histological signs of hepatopancreatic tissues, i.e., acute hepatopancreatic necrosis disease (AHPND) and non-AHPND. To investigate how toxin-producing AHPND and toxin-lacking non-AHPND VP could lead to EMS, growth characteristics and transcriptomic analyses of the representative strains, 5HP and 2HP, were compared. Non-pathogenic VP represented by strain S02 was also used. Two types of growth media included rich medium represented by tryptic soy broth plus 1.5% NaCl (TSB) and depleted media represented by artificial seawater (SW) and spent seawater (SSW). SSW refers to a sterile used-SW medium from healthy shrimp rearing or shrimp-
