Query: NC_008701:1582839 Pyrobaculum islandicum DSM 4184, complete genome
Lineage: Pyrobaculum islandicum; Pyrobaculum; Thermoproteaceae; Thermoproteales; Crenarchaeota; Archaea
General Information: Hyperthermophilic anaerobe. Pyrobaculum islandicum was isolated from water from a geothermal power plant in Iceland. This organism is able to grow lithotrophically and organotrophically using hydrogen or organic matter as the electron donors and sulfur, sulfite, and thiosulfate as electron acceptors.
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.
