Query: NC_014032:1408967 Salinibacter ruber M8 chromosome, complete genome
Lineage: Salinibacter ruber; Salinibacter; Rhodothermaceae; Bacteroidetes Order II; Bacteroidetes; Bacteria
General Information: Salinibacter ruber (strain M8) is a brightly red-pigmented, motile, rod-shaped, extremely halophilic Gram-negative bacterium isolated from a saltern crystallizer pond in Mallorca, Spain. It grows optimally at salt concentrations between 20 and 30% and does not grow below 15% salt. S. ruber is among the most halophilic organisms known within the domain Bacteria. This organism is an extremely halophilic aerobe originally isolated from saltern crystallizer ponds in Spain. These bacteria can coexist in significant colonies with halophilic archaea under saline conditions. In contrast to other bacteria they do not regulate their intracellular salt conditions through proton pumps, but instead their protein makeup has adapted to be functional under high ionic conditions.
Subject: NC_003112:149593 Neisseria meningitidis MC58, complete genome
Lineage: Neisseria meningitidis; Neisseria; Neisseriaceae; Neisseriales; Proteobacteria; Bacteria
General Information: The B serogroup is responsible for many of the meningitis outbreaks in the developed world. This strain was isolated from a case of invasive infection. 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.
