Query: NC_014029:3501500 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_008228:3679949 Pseudoalteromonas atlantica T6c, complete genome
Lineage: Pseudoalteromonas atlantica; Pseudoalteromonas; Pseudoalteromonadaceae; Alteromonadales; Proteobacteria; Bacteria
General Information: Isolated from a biofilm from San Diego Bay in California. Marine biofilm bacterium associated with shell disease in shellfish. A common marine bacterium that exists both in the water column, and in biofilms attached to surfaces. This organism produces a well characterized, commercially important agarase. Pseudoalteromonas atlantica has been isolated from lesions on crabs with shell disease. Shell disease is characterized by progressive degradation of the shell, often leading to an infection of the hemolymph (blood) and may be caused by Pseudoalteromonas, Alteromonas, Vibrio, or other marine organisms. In addition to producing extracellular enzymes which attack the shell, Pseudoalteromonas atlantica produces a the lipopolysaccharide which has been shown to be a potential virulence factor in shell disease.
