Subspecies typing of Vibrio parahaemolyticus by pulsed-field gel electrophoresis.
Vibrio parahaemolyticus is one of the most important food-borne pathogens in Taiwan, Japan, and other costal regions. We report on the development of a pulsed-field gel electrophoresis (PFGE) method for the molecular typing of this pathogen. Genomic DNA was digested with SfiI, and the fragments were resolved on 1% agarose with a contour-clamped homogeneous electric field apparatus set at 190 V ...
متن کاملEvaluation of four methods for enumeration of Vibrio parahaemolyticus.
Two membrane filter (MF) and two most-probable-number methods for enumerating Vibrio parahaemolyticus were compared. The MF methods used elevated-temperature incubations (41 and 42 degrees C) and were more specific than the most-probable-number methods (conducted at 35 degrees C). The MF method with a hydrophobic grid and a repair step was most effective.
متن کاملDetection of Vibrio parahaemolyticus in cockle (Anadara granosa) by PCR.
This study aimed to determine the occurrence of Vibrio parahaemolyticus in cockles (Anadara granosa) at a harvesting area and to detect the presence of virulent strains carrying the thermostable direct hemolysin (tdh) and TDH-related hemolysin genes (trh) using PCR. Of 100 samples, 62 were positive for the presence of V. parahaemolyticus with an MPN (most probable number) value greater than 3.0...
