Vibrio harveyi (Gram-Negative, Bioluminescent, Marine Bacteria Species)


Vibrio harveyi General Facts:
  • Species of gram-negative, bioluminescent, marine bacteria.
  • Organism implicated in the production of marine mucilage or marine snow, based on samples collected by ocean going vessels.
  • Vibrio harveyi bacteria have been shown to communicate via quorum sensing - enabling them to coordinate the production of virulence factors & also bioluminescense (see culture plate opposite).
Vibrio harveyi Bacteriology:
  • Genus - Vibrio.
  • Shape - rod-shaped
  • Staining -Gram negative.
  • Motility - Motile - has polar flagella.
  • Respiration - Facultatively anaerobic
  • Other - Halophilic.
  • Growth temperature - between 4°C & 35°C.
  • Locations - free-swimming in tropical marine waters.
  • Commensal - gut microflora of marine animals.
Vibrio harveyi Pathogenicity:
  • Both a primary & opportunistic pathogen of marine animals.
  • Corals - Gorgonian corals.
  • Molluscs - Oysters
  • Marine crustaceans - Prawns, Lobsters,
  • Fish - Asian Sea Bass, Barramundi, Common Snook, Milkfish, Seahorses, Turbot.
  • Produces a condition called luminous vibriosis - affecting commercially farmed penaeid prawns.

Cronica Universale - Written By Giovanni Villani, Matteo Villani, Filippo Villani


Giovanni Villani & Cronica Universale:
  • Giovanni Villani (1275-1348) begins the Cronica Universale.
  • It was written in Italian rather than Latin.
  • The Cronica Universale started from Biblical times.
  • Very quickly afterwards Giovanni began to write carefully about the events that occurred during his own time.
  • The statistical data he documented, and the detached approach, was unparalleled for the times.
  • His clear business-like mind, with his keen observations on people, was very useful for this task.
  • The historical events are reported just as he heard them, with little personal interpretation.
  • Giovanni Villani was clearly a chronicler & not a historian.
  • Giovanni's death by bubonic plague (Black Death) in 1348 stopped the writing of the Cronica Universale.
Matteo Villani & Cronica Universale:
Filippo Villani & Cronica Universale:
  • Filippo was the son of Matteo Villani.
  • Filippo continued the writing of the Cronica Universale, after his father's death, until 1410.
