Query: NC_017513:9081 Neisseria meningitidis G2136 chromosome, complete genome Lineage: Neisseria meningitidis; Neisseria; Neisseriaceae; Neisseriales; Proteobacteria; Bacteria General Information: 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). 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.

General Information: Citrobacter koseri ATCC BAA-895 is a clinical isolate from a human infant. Causative agent of neonatal meningitis. Citrobacter koseri, previously known as Citrobacter diversus, Levinea diversus or Levinea malonatica resides in a wide range of environments, including soil, water and food products. It is an occasional inhabitant of human and animal intestines, but is mainly characterized as being a causative agent of neonatal meningitis with an extreme high rate of multiple brain abscess initiations and a concomitant high moratility rate. The bacteria are used in neonatal rat models to study the mechanism of blood-brain barrier penetration, host immune response evasion and its resistance to phagocytotic killing.
