The quorum regulatory cascade is poorly characterized in Vibrio parahaemolyticus, in part because swarming and pathogenicity - the hallmark traits of the organism - are repressed by this scheme of gene control. As a consequence, many isolates appear silenced for quorum sensing via phase variation. I...
ORGANISM(S): Vibrio parahaemolyticus 
Here we probe the global response to calcium in the marine bacterium and pathogen Vibrio parahaemolyticus by using transcriptome, reporter and phenotypic analyses. Swarming gene expression and motility were enhanced by calcium. Calcium also stimulated expression and function of one of the organism...

Vibrio parahaemolyticus senses surfaces via impeded rotation of its polar flagellum. We have exploited this surface-sensing mechanism to trick the organism into thinking it is on a surface when it is growing in liquid. This facilitated studies of global gene expression in a way that avoided many of ...
