Query: NC_007514:904565 Chlorobium chlorochromatii CaD3, complete genome
Lineage: Chlorobium chlorochromatii; Chlorobium; Chlorobiaceae; Chlorobiales; Chlorobi; Bacteria
General Information: Chlorobium chlorochromatii CaD3 was isolated from a phototrophic consortia obtained from a freshwater lake in Germany. Chlorobium chlorochromatii is an green sulfur bacterium isolated from low temperature anaerobic fresh water habitats. This organism grows as part of a phototrophic consortium which consists of a colorless central bacterium surrounded by chlorosome-containing green sulfur epibionts. This organism is able to be grown in pure culture therefore is not an obligate symbiont. This organism is an obligate anaerobic phototroph able to fix nitrogen.
Subject: NC_003317:1443874 Brucella melitensis 16M chromosome I, complete sequence
Lineage: Brucella melitensis; Brucella; Brucellaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: This strain was isolated from an infected goat and is pathogenic in humans. Causes brucellosis and undulant fever. They are highly infectious, and can be spread through contact with infected animal products or through the air, making them a potential bioterrorism agent. Once the organism has entered the body, it can become intracellular, and enter the blood and lymphatic regions, multiplying inside phagocytes before eventually causing bacteremia (spread of bacteria through the blood). Virulence may depend on a type IV secretion system which may promote intracellular growth by secreting important effector molecules. This organism is a facultative intracellular bacteria that causes abortion in wild and domestic animals, usually goats or sheep, and undulant fever in humans. Brucellosis is a major health problem in the Mediterranean region and parts of Asia, Africa, and Latin America, where it causes severe economic losses. The disease is transmitted to humans by nonpasteurized milk and milk products or by direct contact with infected animals or carcasses.
