Query: NC_017516:917817 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.

General Information: Sorangium cellulosum 'So ce 56' produces a large number of bioactive compounds, such as, the antifungal soraphen and the anticancer agent epothilone. This organism, like other myxobacteria, undergoes a complex development and differentiation pathway. When cell density increases, the organism switches to "social motility" where aggregates of cells can gather together into masses termed fruiting bodies that may consist of up to 100 000 cells. The motility system is not dependent on flagella like most bacteria, but instead relies on twitching pili: short extracellular appendages that may function analogously to oars in a rowboat. The myxobacteria have proved to be a rich source of novel natural products. Sorangium cellulosum produces a number of antibacterial, antifungal and cytotoxic substances which are being studies for therapeutic applications.
