Query: NC_010163:1193237 Acholeplasma laidlawii PG-8A chromosome, complete genome
Lineage: Acholeplasma laidlawii; Acholeplasma; Acholeplasmataceae; Acholeplasmatales; Tenericutes; Bacteria
General Information: Acholeplasma species are widely distributed in the nature and can be detected and isolated from different plant, avian, and mammalian sources. Acholeplasma laidlawii is found in soil, compost, wastewaters, cell cultures as well as in human tissues and in many animal species (birds, bovine, goat, equine, ovine, porcine, feline, rodent, primates). Acholeplasma laidlawii is capable of synthesizing glucose using a pyrophosphate-dependent 6-phosphofructokinase which has also been detected in other acholeplasmas (a good example of flexible metabolism). Additionally, Acholeplasma laidlawii and phytoplasmas are the only mollicutes known to use the universal genetic code, in which UGA is a stop codon.
Subject: NC_003317:392271 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.
