Query: NC_017516:123618 Neisseria meningitidis H44/76 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.

Subject: NC_010376:606000 Finegoldia magna ATCC 29328, complete genome
Lineage: Finegoldia magna; Finegoldia; Clostridiales Family XI; Clostridiales; Firmicutes; Bacteria
General Information: It is isolated most frequently from various infection sites, including soft tissue, bone and joint, and diabetic foot infections. This species, formerly Peptostreptococcus magnus, is a commensal bacterium colonizing human skin and mucous membranes. It has been shown to cause valve endocarditic in humans. Gram-positive anaerobic cocci (GPAC) are a major part of the normal human flora colonizing skin and mucous membranes of the mouth and gastrointestinal tracts. In GPAC, Finegoldia magna (formerly Peptostreptococcus magnus) has the highest pathogenicity and is isolated most frequently from various infection sites, including soft tissue, bone and joint, and diabetic foot infections.
