Query: NC_015683:2469481 Corynebacterium ulcerans BR-AD22 chromosome, complete genome
Lineage: Corynebacterium ulcerans; Corynebacterium; Corynebacteriaceae; Actinomycetales; Actinobacteria; Bacteria
General Information: They may be found as members of the normal microflora of humans, where these bacteria find a suitable niche in virtually every anatomic site. Corynebacterium ulcerans is commonly associated with dairy animals and unpasturized dairy products. This organism has been implicated in bovine mastitis and can cause skin infections and a diptheria-like disease in humans.
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.
