Demonstration ofInvasiveness ofVibrio parahaemolyticus in AdultRabbits byImmunofluorescence

antibody, andorganspecimens were cultured forisolation oftheinoculated Vibrio strain. Allstrains tested penetrated intothelamina propria oftheileumandwereisolated fromthecultured tissue specimens, indicating thattheorganism iscapable ofmorethanasuperficial colonization ofthegut.Thepresence ofVibrio incultured tissue specimens suggests invasion ofdeeper tissue byeither thelymphatic orthecirculatory system. In1967, Yahagi(20) reported thelocalization ofaKanagawa-positive strain ofVibrio para
