Abstract

The human pathogenic bacterium, Vibrio parahaemolyticus, generally associated with seafoods was tested for its ability to form biofilm on stainless steel surfaces. This bacterium possessed good adhering ability and formed a biofilm with a cell density of 2.43 x 104 cm2 on stainless steel surface in a 10-day experimental period. The biofilm bacteria showed increased resistance to commonly used sanitizers such as iodophor and hypochlorite than planktonic cells. Exposure to iodophor at as high as 10 μg ml-1 and hypochlorite at 100 and 200 μg ml-1 for 5 min showed a reduction in numbers by only 2-3 log units and failed to completely inactivate biofilm cells. These results suggest that V. parahaemolyticus can form biofilm and pose a serious problem in seafood processing facilities.
