Vibrio fluvialis

Description and Significance

Vibrio fluvialis was first announced in 1977 with its original name of group F and group EF- 6 virbios. Researchers have isolated V. fluvialis from the stool of various infected patients with acute diarrheal illnesses, gastroenteritis, and extraintestinal infections. Vibrio fluvialis is a worldwide microbe found predominantly in coastal environments; seas, estuaries, salty waters. The microbe contains curved cell morphology as the cell rod has a straight to curved ratio. V. fluvialis uses polar flagellar motility to propel itself in liquid at high speeds of 100,000 rpm. This gram-negative species are short and slim anaerobes that form S shapes and spirals.

According to the U.S. Centers for Disease Control and Prevention, vibrio infections have tripled from 1996- 2010. Vibrio fluvialis is less common than other vibrio species, however; it is easily pathogenically transmitted through ingestion of contaminated raw shellfish and over exposure to brackish waters.

Genome Structure

The genome structure of V. fluvialis consists of two circular chromosomes. In detail, together the two chromosomes have more or less than 4,000 protein coding genes, 60-100 tRNA, and 5-30 rRNA. Sequencing of many strands of Vibrio fluvialis determined the genome size to range from 4.50 Mb to 5.50 Mb. An abundant amount of virulence factors and antimicrobial resistance genes were identified in the reason of high levels of homologous recombination. The evolution of pathogenesis in Vibrio fluvialis relies on its gene structure.
