Query: NC_007712:532500 Sodalis glossinidius str. 'morsitans', complete genome
Lineage: Sodalis glossinidius; Sodalis; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: Sodalis glossinidius is known exclusively in endosymbiosis with tsetse flies. It is maternally transmitted, and is one of the few bacterial endosymbionts of insects that can be cultured successfully in vitro. Genome data reveals a high proportion of pseudogenes in this species, many of which were, in their functional state, involved in defense or transport of carbohydrates and inorganic ions. This suggests a degenerative adaptation to the immunity and restricted nutritional status of the host.
Subject: NC_007618:262415 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.
