  • Quorum Sensing

    • For instance, the bioluminescent luciferase produced by Vibrio fischeri would not be visible if it were produced by a single cell.
    • In 2002, the crystal structure of the receptor LuxP of Vibrio harveyi with its inducer AI-2 (which is one of the few biomolecules containing boron) bound to it was also determined.
    • A comparative genomic and phylogenetic analysis of 138 genomes of bacteria, archaea, and eukaryotes found that "the LuxS enzyme required for AI-2 synthesis is widespread in bacteria, while the periplasmic binding protein LuxP is present only in Vibrio strains," leading to the conclusion that either "other organisms may use components different from the AI-2 signal transduction system of Vibrio strains to sense the signal of AI-2 or they do not have such a quorum sensing system at all. " Certain bacteria can produce enzymes called lactonases that can target and inactivate AHLs.

    • They include a wide variety of pathogens, such as Escherichia, Salmonella, Vibrio, Helicobacter, and many other notable genera.

  • Types of Microorganisms

    • They exist in four major shapes: bacillus (rod shape), coccus (spherical shape), spirilla (spiral shape), and vibrio (curved shape).

  • Plasmids and Lysogeny

    • Specifically, the bacterium, Vibrio cholerae, is transformed into a toxic strain upon infection with the bacteriophage.

  • Group Translocation

    • The GlyGly-CTERM/rhombosortase system, found in the Shewanella, Vibrio, and a few other genera, seems involved in the release of proteases, nucleases, and other enzymes.

  • Chemotaxis

    • Many bacteria, such as Vibrio, are monoflagellated and have a single flagellum at one pole of the cell.
