Query: NC_008816:518895 Prochlorococcus marinus str. AS9601, complete genome Lineage: Prochlorococcus marinus; Prochlorococcus; Prochlorococcaceae; Prochlorales; Cyanobacteria; Bacteria General Information: This cyanobacterium was collected in the Arabian Sea at a depth of 50 meters and isolated by filter fractionation. It belongs to Clade HL-II, the most abundant group in the North Atlantic and North Pacific Oceans, often constituting over 90% of the total population. Marine cyanobacterium. This non-motile bacterium is a free-living marine organism that is one of the most abundant, as well as the smallest, on earth, and contributes heavily to carbon cycling in the marine environment. This cyanobacterium grows in areas of nitrogen and phosphorus limitation and is unique in that it utilizes divinyl chlorophyll a/b proteins as light-harvesting systems instead of phycobiliproteins. These pigments allow harvesting of light energy from blue wavelengths at low light intensity.

General Information: This strain is a type A isolate from the soil. It can establish gas gangrene in a murine experimental model. Causative agent of gas gangrene. 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. This organism is a causative agent of a wide spectrum of necrotic enterotoxicoses. It also causes such animal diseases as lamb dysentery, ovine enterotoxemia (struck), pulpy kidney disease in lambs and other enterotoxemias in lambs and calves. It is commonly found in the environment (soil, sewage) and in the animal and human gastrointestinal tract as a member of the normal microflora. It is a fast growing (generation time 8-10 min) anaerobic flesh-eater. Active fermentative growth is accompanied by profuse generation of molecular hydrogen and carbon dioxide. It is also oxygen tolerant which makes it an easy object to work with in laboratories. Known isolates belong to five distinct types (A, B, C, D, and E) that are distinguished based on the specific extracellular toxins they produce. Known isolates belong to five distinct types (A, B, C, D, and E) that are distinguished based on the specific extracellular toxins they produce. All types produce the alpha toxin (phospholipase C). Type A strains that cause gas gangrene produce alpha toxin, theta (hemolysin), kappa (collagenase), mu (hyaluronidase), nu (DNAse) and neuraminidase which are all the enzymatic factors aiding the bacterium in invading and destruction of the host tissues. Type C strains produce alpha toxin, beta toxin and prefringolysin enteritis. In addition to alpha toxin, Type B strains produce beta toxin, types B and D produce the pore forming epsilon toxin and type E strains produce iota toxin.
