title: [Incidence of Kanagawa phenomenon-positive and -negative Vibrio parahaemolyticus strains isolated from traveller's diarrhea and their relation to tdh and trh genes].
abstract: A total of 1,319 strains of Vibrio parahaemolyticus isolated from traveller's diarrhea were analysed for Kanagawa phenomenon (KP) with the Wagatsuma blood agar test and the results were also compared with those of analyses of tdh and trh genes which encode thermostable direct hemolysin (tdh) and TDH-related hemolysin (trh). The majority of the strains (1,152 strains) counting 87.3% had positive KP, among which 1,049 and 103 strains were only tdh and both tdh and trh-positive ones, respectively. However, 167 strains counting 12.7%, which is quite high compared to the previous report, were found to have negative KP, among which 94 and 24 strains were only trh and both tdh and trh-positive ones, respectively.
