Query: NC_015760:8914 Streptococcus salivarius CCHSS3, complete genome
Lineage: Streptococcus salivarius; Streptococcus; Streptococcaceae; Lactobacillales; Firmicutes; Bacteria
General Information: The commensal bacterium Streptococcus salivarius is predominant specie of the human oropharyngeal tract and exerts an important role in oral ecology. Streptococcus salivarius is an aerobic, gram-positive coccus. This organism is the most common organism isolated from the human oral cavity. Streptococcus salivarius can also be an opportunistic pathogen causing endocarditis, blood infection, and peritonitis. Streptococci are Gram-positive, nonmotile, nonsporeforming, catalase-negative cocci that occur in pairs or chains. Members of this genus vary widely in pathogenic potential. Most streptococci are facultative anaerobes, and some are obligate anaerobes.
Subject: NC_011184:2723000 Vibrio fischeri MJ11 chromosome I, complete sequence
Lineage: Aliivibrio fischeri; Aliivibrio; Vibrionaceae; Vibrionales; Proteobacteria; Bacteria
General Information: This strain was isolated from a pinecone fish, Monocentris japonica, light-emitting organs in Japan. This genus is abundant in marine or freshwater environments such as estuaries, brackish ponds, or coastal areas; regions that provide an important reservoir for the organism in between outbreaks of the disease. Vibrio can affect shellfish, finfish, and other marine animals and a number of species are pathogenic for humans. This organism is found in marine environments and was originally named by Bernard Fischer during a sea voyage in the 1800s. It is a symbiont in fish and squids and is responsible for light generation in those organisms, which use it as a defense mechanism to avoid predators.
