Query: NC_014029:2388500 Yersinia pestis Z176003 chromosome, complete genome

Lineage: Yersinia pestis; Yersinia; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria

General Information: It was isolated from a dead marmot in Tibet Autonomous Region, China. Gram-negative straight rods, sometimes approaching a spherical shape. Y.pestis is always nonmotile. It is the causative agent of plague which is primarily a disease of wild rodents. Y.pestis is transmitted among wild rodents by fleas, in which the bacteria multiply and block the esophagus and the pharynx. The fleas regurgitate the bacteria when they take their next blood meal. Bacteria are transmitted subcutaneously to humans by the bite of infected fleas, but also by air, especially during pandemics of disease. Infective flea bites produce the typical bubonic form of plague in humans.

Subject: 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.
