(Submitter supplied) This study was conducted to study which genes or functions become important or expendable in two V. cholerae mutants compared to the WT. This was assessed directly by conjugating a Mariner Transposon with WT or mutant cells and obtaining a bank of hundreds of thousands of mutants which we consider as the T=0. We then subjected these banks to 16 generations in rich media with or without 50% MIC of tobramycin (which we call T=16gen). more...

(Submitter supplied) In this study, we show that ManR (VC1825) activates the transcription of the mannose operon in M9 medium supplemented with fructose or mannose, and when manR is impaired Vibrio cholerae cells fail to colonize the intestine and host survival is significantly prolonged in a fruit fly Drosophila melanogaster infection model. To identify other target genes of ManR, transcriptome analysis was performed in wild-type V. more...

(Submitter supplied) Purpose: to characterize the regulatory targets of an AraC-like transcriptional regulator (VC0513) encoded on the Vibrio Seventh Pandemic Island -II (VSP-II) in V. cholerae O1 El Tor N16961 Methods: RNA was isolated from a wild-type N16961 carrying an IPTG-inducible copy of vc0513, vc0515, or an empty vector control Results: vc0513 induction significantly increased expression of other VSP-II encoded genes relative to the empty vector control Conclusions: our study represents the first analysis of a transcriptional regulator encoded on the VSP-II island

(Submitter supplied) Bactericidal antibiotics are powerful drugs because they not only inhibit essential bacterial functions, but convert them into toxic processes. Many bacteria are remarkably tolerant against antibiotics, due to inducible damage repair responses. How these responses promote whole population tolerance in important human pathogens is poorly understood. The two-component system VxrAB of the diarrheal pathogen Vibrio cholerae, a model system for tolerance against cell wall damaging (e.g., beta-lactam) antibiotics, is required for high-level beta-lactam tolerance. more...

(Submitter supplied) Blue light (BL) is a major environmental factor that affects the physiology, behavior, and infectivity of bacteria as it contributes to the generation of reactive oxygen species (ROS) while increasing photo-oxidative stress in cells. However, precise photo-oxidative response mechanism in non-phototrophic bacteria is yet to be elucidated. In this study, we investigated the effect of BL in Vibrio cholerae by using genetics and transcriptome profiling. more...

(Submitter supplied) Replication and segregation are the two main processes that maintain chromosomes in growing cells. In bacteria, replication and transcription have been proposed to provide motive force in chromosome segregation. Recently, ParB2, a segregation protein, encoded by V. cholerae chromosome II (chrII) was also found to influence chrII replication. V. cholerae chrII replication is primarily controlled by its specific initiator protein, RctB. more...

(Submitter supplied) Vibrio cholerae is a Gram negative, motile, facultative anaerobic bacterium, and the causative agent of cholera, a severe diarrhoeal disease, which untreated can rapidly lead to dehydration, hypotensive shock, and death. Cholera is a significant human disease that is estimated to affect 3-5 million people each year. The mechanism by which V. cholerae regulates virulence gene expression in vivo is unknown, but a number of studies have suggested that low molecular weight signally molecules may be important in modulating gene expression. more...

(Submitter supplied) Vibrio cholerae, the cause of cholera, can grow in a variety of environments outside of human hosts. During infection, the pathogen must adapt to significant environmental alterations, including the elevated temperature of the human gastrointestinal tract. σ32, an alternative sigma factor encoded by rpoH, activates transcription of genes involved in the heat-shock response in several bacterial species. more...
