Query: NC_014121:3776902 Enterobacter cloacae subsp. cloacae ATCC 13047 chromosome, complete
Lineage: Enterobacter cloacae; Enterobacter; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: Enterobacter species are found in natural environments such as water, sewage, soil, and vegetables; some species are found in human and animal species. Enterobacter cloacae is a prevalent nosocomial pathogen as it is highly resistant to disinfectants and antimicrobial agents. E.cloacae subsp. cloacae strain ATCC 13047 was isolated from human cerebrospinal fluid in 1890 and is the type strain. These "ICU bugs" cause significant morbidity and mortality, and infection management is complicated by multiple antibiotic resistance. These bacteria possess inducible beta-lactamases, which are undetectable in vitro but are also responsible for resistance during treatment.
Subject: NC_003305:1297785 Agrobacterium tumefaciens str. C58 chromosome linear, complete
Lineage: Agrobacterium tumefaciens; Agrobacterium; Rhizobiaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: Gram-negative soil bacterium. This is the most widely studied species in the genus. Strains of Agrobacterium are classified in three biovars based on their utilisation of different carbohydrates and other biochemical tests. The differences between biovars are determined by genes on the single circle of chromosomal DNA. Biovar differences are not particularly relevant to the pathogenicity of A. tumefaciens, except in one respect: biovar 3 is found worldwide as the pathogen of gravevines. This species causes crown gall disease of a wide range of dicotyledonous (broad-leaved) plants, especially members of the rose family such as apple, pear, peach, cherry, almond, raspberry and roses. Because of the way that it infects other organisms, this bacterium has been used as a tool in plant breeding. Any desired genes, such as insecticidal toxin genes or herbicide-resistance genes, can be engineered into the bacterial DNA, and then inserted into the plant genome. This process shortens the conventional plant breeding process, and allows entirely new (non-plant) genes to be engineered into crops.
