Query: NC_012029:11986 Halorubrum lacusprofundi ATCC 49239 chromosome 1, complete genome
Lineage: Halorubrum lacusprofundi; Halorubrum; Halobacteriaceae; Halobacteriales; Euryarchaeota; Archaea
General Information: Formerly Halobacterium lacusprofundi, this organism is an extremely halophilic archaeon isolated from Deep Lake, Antarctica. Extremely halophilic archaeon isolated from the Antarctic. Halorubrum lacusprofundi is a red pigmented halophilic archaeon which has been found in hypersaline marine enviornments. Originally thought to be a psychrophile, further research determined that the optimum temperature for growth for Halorubrum lacusprofundi was from 31 - 37 degrees C.
Subject: NC_007618:1593886 Brucella melitensis biovar Abortus 2308 chromosome I, complete
Lineage: Brucella abortus; Brucella; Brucellaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: This strain is a standard laboratory strain. It is virulent for humans and cattle. Causes bovine brucellosis. 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 was first noticed on the island of Malta. It is the primary cause of bovine brucellosis, which results in enormous (billions of dollars) economic losses due primarily to reproductive failure and food losses. In man, it causes undulant fever, a long debilitating disease that is treated by protracted administration of antibiotics.
