Roles of thermostable direct hemolysin (TDH) and TDH-related hemolysin (TRH) in Vibrio parahaemolyticus
Vibrio parahaemolyticus is the leading cause of seafood borne bacterial gastroenteritis in the world, often associated with the consumption of raw or undercooked seafood. However, not all strains of V. parahaemolyticus are pathogenic. The thermostable direct hemolysin (TDH) or TDH-related hemolysin (TRH) encoded by tdh and trh genes, respectively, are considered major virulence factors in V. pa...
متن کاملIsolation, Detection and Genomic Differentiation of Vibrio cholerae and Vibrio parahaemolyticus in Bachok, Kelantan
The objective of this study was to determine the genetic diversity and virulence factors of Vibrio cholerae and V. parahaemolyticus from selected aquatic environments in Bachok, Kelantan, Malaysia. Out of 50 water samples, 33 were confirmed with the presence of presumptive V. cholerae and V. parahaemolyticus based on biochemical tests. Primers targeting toxR gene specific for V. cholerae (800bp...
متن کاملHigh frequency of virulence factor genes tdh, trh, and tlh in Vibrio parahaemolyticus strains isolated from a pristine estuary.
Virulence factor genes encoding the thermostable direct hemolysin (tdh) and the thermostable direct hemolysin-related hemolysin (trh) are strongly correlated with virulence of the emergent human pathogen Vibrio parahaemolyticus. The gene encoding the thermolabile hemolysin (tlh) is also considered a signature molecular marker for the species. These genes are typically reported in very low perce...
متن کاملDetection of tdh and trh genes in Vibrio parahaemolyticus isolated from Corbicula moltkiana prime in West Sumatera, Indonesia.
The occurrence of Vibrio parahaemolyticus in raw Corbicula moltkiana Prime from Lake Singkarak and Pasar Raya Padang market and in cooked samples in West Sumatera, Indonesia, was studied. Thirteen raw and seven cooked bivalve samples were positive using CHROMAgar Vibrio medium. All 47 V parahaemolyticus isolates were positive for toxR gene but negative for trh. However, 36% (17/47) of V parahae...
متن کاملVirulence and antimicrobial resistance characteristics of Vibrio parahaemolyticus isolated from environment, food and clinical samples in the south of Vietnam, 2010
Background Vibrio parahaemolyticus is a major cause of food poisoning in many countries. The rapid cases of this agent in recent years made it become an important etiology. However, the relationship between strains isolated from environment, food and clinical samples is still unclear. The presence of antimicrobial resistance and virulence factors such as tdh (thermostable direct hemolysin), trh...
