Description

Antibacterial effects of pepsin and trypsin on acid-injured cells of Vibrio parahaemolyticus, a causative bacterium of food-borne infection, were investigated, and the following results were obtained: (1) Pepsin exerts an inhibitory action on the acid-injured cells and accelerates their deaths at pH 4-5. (2) trypsin does not exert any inhibitory action even in the presence of cholate, allowing the recovery of the acid-injured cells at about pH 8.0, which is the optimum pH for the growth of V. parahaemolyticus. From these results, the possible fate of this bacterium in the human gastrointestinal tract was discussed in relation to the prevention of this food-borne infection.
