Query: NC_007519:3527207 Desulfovibrio alaskensis G20 chromosome, complete genome
Lineage: Desulfovibrio alaskensis; Desulfovibrio; Desulfovibrionaceae; Desulfovibrionales; Proteobacteria; Bacteria
General Information: This organism is a spontaneous nalidixic acid-resistant derivative of a wild-type strain (G100A) that was isolated from an oil well corrosion site. It has been cured of a 2.3 Kb cryptic plasmid as well. This organism is one of the few extensively studied sulfate-reducing bacteria.
Subject: NC_008767:1888950 Neisseria meningitidis FAM18, complete genome
Lineage: Neisseria meningitidis; Neisseria; Neisseriaceae; Neisseriales; Proteobacteria; Bacteria
General Information: Isolated from a patient with meningococcal septicemia. Causes septicemia and meningitis. The second of two pathogenic Neisseria, this organism causes septicemia and is the leading cause of life-threatening meningitis (inflammation of the meninges, the membrane surrounding the brain and spinal cord) in children. This organism typically residies in the nasopharynx cavity but can invade the respiratory epthelial barrier, cross into the bloodstream and the blood brain barrier, and cause inflammation of the meninges. Pathogenicity factors include the surface proteins (porins and opacity proteins), and the type IV pilus (which is also found in Neisseria gonorrhoeae). Pathogenicity factors include the surface proteins (porins and opacity proteins), and the type IV pilus (which is also found in Neisseria gonorrhoeae). This organism, like Neisseria gonorrhoeae, is naturally competent, and protein complexes at the cell surface recognize the uptake signal sequence in extracellular DNA, an 8mer that is found at high frequency in Neisseria chromosomal DNA.
