Query: NC_014029:792719 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_010159:3120642 Yersinia pestis Angola, complete genome

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

General Information: This strain was isolated prior to 1985 and belongs to the antiqua biovar. It can ferment rhamnonse and melibiose which is a property usually associated with Yersinia pseudotuberculosis. Strain Angola belongs to a group of atypical Yersinia pestis strains with genotypic similarities that are intermediate between Y. pestis and Y. pseudotuberuclosis strains. Genotypic studies indicate that strain Angola is the oldest Y. pestis strain analyzed to date. It carries three plasmids that are similar to other Y. pestis plasmids but have aberrant sizes. The critical virulence factor, the V antigen, is different than that encoded by typical strains of Y. pestis and there is a deletion that affects the F1 operon. Strain Angola has been shown to be virulent by aerosol in mice.
