Query: NC_013971:2408522 Erwinia amylovora ATCC 49946 chromosome, complete genome
Lineage: Erwinia amylovora; Erwinia; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: This bacterium is the causative agent of Fire Blight, a destructive disease of Maloid fruit trees, such as apple and pear. Outbreaks are sporadic in the Northeast, but result in serious damage to roots, blossoms, fruit, and shoots when they occur. The pathogen overwinters in cankers or in smaller limbs. During early spring, in response to both temperature increases and bud development, the bacteria multiplies and may be seen as a yellowish ooze around the perimeter of the canker. Flies and other insects are attracted to the ooze and disperse the inoculum to other trees in the orchard. This species has recently become resistant to streptomycin, an antibiotic traditionally used in its control.
Subject: NC_008228:2295841 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.
