Quorum sensing and silencing in Vibrio parahaemolyticus.
The quorum regulatory cascade is poorly characterized in Vibrio parahaemolyticus, in part because swarming and virulence factors--the hallmarks of the organism--are repressed by this scheme of gene control, and quorum sensing seems to be silenced in many isolates. In these studies, we examine a swarming-proficient, virulent strain and identify an altered-function allele of the quorum regulator ...
متن کاملQuorum sensing regulates type III secretion in Vibrio harveyi and Vibrio parahaemolyticus.
In a process known as quorum sensing, bacteria communicate with one another by producing, releasing, detecting, and responding to signal molecules called autoinducers. Vibrio harveyi, a marine pathogen, uses two parallel quorum-sensing circuits, each consisting of an autoinducer-sensor pair, to control the expression of genes required for bioluminescence and a number of other target genes. Gene...
متن کاملTranscriptional Regulation of the Type VI Secretion System 1 Genes by Quorum Sensing and ToxR in Vibrio parahaemolyticus
Vibrio parahaemolyticus, the leading cause of seafood-associated gastroenteritis, harbors two separate T6SSs on chromosomes 1 and 2, i.e., T6SS1 (VP1386-1420) and T6SS2 (VPA1025-1046). T6SS1 contains at least 7 putative operons: VP1386-1387, VP1388-1390, VP1392-1391, VP1393-1406, VP1400-1406, VP1409-1407, and VP1410-1420. V. parahaemolyticus AphA and OpaR are the two master regulators of quorum...
متن کاملOpaR Controls a Network of Downstream Transcription Factors in Vibrio parahaemolyticus BB22OP
Vibrio parahaemolyticus is an emerging world-wide human pathogen that is associated with food-borne gastroenteritis when raw or undercooked seafood is consumed. Expression of virulence factors in this organism is modulated by the phenomenon known as quorum sensing, which permits differential gene regulation at low versus high cell density. The master regulator of quorum sensing in V. parahaemol...
متن کاملDetection of Virulence Genes Tcpa and Ctxb in Isolates from Surface Water and Salt Water Samples in Golestan, Iran
ABSTRACT Background and Objective: Vibrio is a genus of bacteria that are widely distributed in aquatic environments. The genus includes several important pathogens that endanger farm animals and humans who ingest seafood or water contaminated with the bacteria. Virulence of Vibrio spp. is regulated by ctxAB and tcpA genes. The aim of this study...
