Multiple quorum‐sensing circuits function in parallel to control virulence and biofilm
formation in Vibrio cholerae. In contrast to other bacterial pathogens that induce virulence …

The production of virulence factors including cholera toxin and the toxin-coregulated pilus in
the human pathogen Vibrio cholerae is strongly influenced by environmental conditions. The …

Quorum-sensing bacteria communicate with extracellular signal molecules called
autoinducers. This process allows community-wide synchronization of gene expression. A …

The marine bacterium Vibrio harveyi possesses two quorum sensing systems (System 1 and
System 2) that regulate bioluminescence. Although the Vibrio cholerae genome sequence …

Shewanella putrefaciens is a facultative anaerobe that can use metal oxides as terminal
electron acceptors during anaerobic respiration. Two proteins, MtrB and Cct, have been …

Ralstonia solanacearum, which causes bacterial wilt of diverse plants, produces copious
extracellular polysaccharide (EPS), a major virulence factor. The function of EPS in wilt …

SXT is an integrative and conjugative element (ICE) that confers resistance to multiple
antibiotics upon many clinical isolates of Vibrio cholerae. In most cells, this∼ 100 Kb …

As reported previously for Ralstonia solanacearum strain GMI1000, wild‐type strains AW1
and K60 were shown to produce Hrp pili. AW1 and K60 mutants lacking Hrp pili still …

The Escherichia coli gcvB gene encodes a small RNA transcript that is not translated in vivo.
Transcription from the gcvB promoter is activated by the GcvA protein and repressed by the …

Vibrio cholerae is a Gram‐negative bacterium that causes the acute diarrhoeal disease
cholera. After the bacterium is ingested, it passes through the digestive tract, encountering …
