Query: NC_012947:3947238 Escherichia coli 'BL21-Gold(DE3)pLysS AG' chromosome, complete
Lineage: Escherichia coli; Escherichia; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: Isolation: Derivative of E. coli strain B; Temp: Mesophile; Temp: 37 C; Habitat: Host, Human intestinal microflora. This organism was named for its discoverer, Theodore Escherich, and is one of the premier model organisms used in the study of bacterial genetics, physiology, and biochemistry. This enteric organism is typically present in the lower intestine of humans, where it is the dominant facultative anaerobe present, but it is only one minor constituent of the complete intestinal microflora. E. coli, is capable of causing various diseases in its host, especially when they acquire virulence traits. E. coli can cause urinary tract infections, neonatal meningitis, and many different intestinal diseases, usually by attaching to the host cell and introducing toxins that disrupt normal cellular processes.
Subject: NC_011770:1226923 Pseudomonas aeruginosa LESB58, complete genome
Lineage: Pseudomonas aeruginosa; Pseudomonas; Pseudomonadaceae; Pseudomonadales; Proteobacteria; Bacteria
General Information: Pseudomonas aeruginosa LESB58 is a member of the Liverpool epidemic strains (LES) first isolated at the Liverpool Cystic Fibrosis (CF) clinic center. These isolates are highly virulent and readily transfered between CF patients and to non-CF individuals. Bacteria belonging to the Pseudomonas group are common inhabitants of soil and water and can also be found on the surfaces of plants and animals. Pseudomonas bacteria are found in nature in a biofilm or in planktonic form. Pseudomonas bacteria are renowned for their metabolic versatility as they can grow under a variety of growth conditions and do not need any organic growth factors. This organism is an opportunistic human pathogen. While it rarely infects healthy individuals, immunocompromised patients, like burn victims, AIDS-, cancer- or cystic fibrosis-patients are at increased risk for infection with this environmentally versatile bacteria. It is an important soil bacterium with a complex metabolism capable of degrading polycyclic aromatic hydrocarbons, and producing interesting, biologically active secondary metabolites including quinolones, rhamnolipids, lectins, hydrogen cyanide, and phenazines. Production of these products is likely controlled by complex regulatory networks making Pseudomonas aeruginosa adaptable both to free-living and pathogenic lifestyles. The bacterium is naturally resistant to many antibiotics and disinfectants, which makes it a difficult pathogen to treat.
