Research Abstract

Type III secretion system 2 of Vibrio parahaemolyticus is essential for entrotoxicity. However, qualitative and quantitative regulation of T3SS2 is unclear. In this study, I identified two novel genes responsible for secretory regulation of T3SS2. The knock-out strains of these genes caused a dramatic change in a secretory pattern of T3SS2 secreted proteins, indicating that these genes are involved in qualitative and quantitative secretory regulation of Vibrio parahaemolyticus T3SS2.
