Query: NC_002946:1786000 Neisseria gonorrhoeae FA 1090, complete genome
Lineage: Neisseria gonorrhoeae; Neisseria; Neisseriaceae; Neisseriales; Proteobacteria; Bacteria
General Information: A serum-resistant streptomycin-resistant proline-requiring strain isolated from a patient with disseminated gonococcal infections. Causes gonorrhea. One of two pathogenic Neisseria, this species causes the sexually transmitted disease (STD) gonorrhea, which is the leading reportable STD in adults in the USA. This human-specific organism colonizes and invades the mucosal surface of the urogenital epithelium, crosses the epithelial barrier, and ends up multiplying on the basement membrane. The Opa proteins are responsible for the opaque colony phenotype due to the tight junctions between adjacent Neisseria, and are also responsible for tight adherence to host cells. This organism, like Neisseria meningitidis, is also naturally competent for DNA uptake.
Subject: NC_011898:351792 Clostridium cellulolyticum H10, complete genome
Lineage: Clostridium cellulolyticum; Clostridium; Clostridiaceae; Clostridiales; Firmicutes; Bacteria
General Information: A non-ruminal mesophilic cellulolytic bacterium originally isolated from decayed grass compost. This genus comprises about 150 metabolically diverse species of anaerobes that are ubiquitous in virtually all anoxic habitats where organic compounds are present, including soils, aquatic sediments and the intestinal tracts of animals and humans. This shape is attributed to the presence of endospores that develop under conditions unfavorable for vegetative growth and distend single cells terminally or sub-terminally. Spores germinate under conditions favorable for vegetative growth, such as anaerobiosis and presence of organic substrates. It is believed that present day Mollicutes (Eubacteria) have evolved regressively (i.e., by genome reduction) from gram-positive clostridia-like ancestors with a low GC content in DNA. Clostridium cellulolyticum is a mesophilic cellulolytic bacterium. Cellulose-degradation by C. cellulolyticum has been extensively studied. The cellulolytic enzymes of this organism are bound to a protein scaffold in an extracellular multienzyme complex called a cellulosome.
