Query: NC_012781:302387 Eubacterium rectale ATCC 33656, complete genome
Lineage: Eubacterium rectale; Eubacterium; Eubacteriaceae; Clostridiales; Firmicutes; Bacteria
General Information: Eubacterium rectale ATCC 33656 was isolated from human feces. This genus has been isolated as normal flora from feces, rumen, and periodontal tissue. Eubacterium spp. are thought to play a beneficial role in maintaining the normal ecology of the large intestine, in part by producing chemicals like butyric acid which act to inhibit the growth of other bacteria. These organisms are occasionally isolated from wounds and abscesses and may be an opportunistic pathogen. This genus has also been isolated from sewage and soil.
Subject: NC_003317:1719546 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.
