Vagococcus fluvialis

Description and Significance

Vagococcus fluvialis is a species of lactic acid bacteria that is a gram-positive, catalase-negative cocci that is closely related to the genera Enterococcus and Carnobacterium (1). V. fluvialis is commonly found in aquatic environments like rivers and seawater (2). It is believed to be probiotic in fish, however in mammals it is frequently related to infectious tissue (4).

Genome Structure

The genome size ranges from 2.65 to 3.16 Mb, with roughly 2801 protein-coding genes and 104 RNA genes (4). V. fluvial has one single circular chromosome that contains several plasmids and insertion sequences. The genome is dynamic and adaptable to allow for various environments (5).
