Crude hemolysin from four KP+ strains of Vibrio parahaemolyticus belonging to serotype 02:K3 exhibited a major protein band (molecular weight, 65 kilodaltons (kDa] in addition to a previously known thermostable direct hemolysin band (molecular weight, 21 kDa) in SDS - polyacrylamide slab gel electrophoresis. These strains showed maximum virulence leading to 100% mouse lethality within 2-6 h. It is hypothesized that this 65-kDa protein may play a vital role in the pathogenesis of the disease caused by V. parahaemolyticus.
