Query: NC_007799:968499 Ehrlichia chaffeensis str. Arkansas, complete genome
Lineage: Ehrlichia chaffeensis; Ehrlichia; Anaplasmataceae; Rickettsiales; Proteobacteria; Bacteria
General Information: This strain is the first isolate of Ehrlichia chaffeensis, which was obtained from a patient on an army base in Arkansas, USA in 1990. Causes disease in humans. This organism is an obligate intracellular pathogen that exists within vacuoles in the cytoplasm of monocytes or granulocytes. Transferred during an insect (tick) bite, it can cause disease in humans (human monocytic ehrlichiosis) and can reside in several other animals and is a problem in immunocompromised patients. The bacterium inhibits phagosome-lysozome fusion as well as programmed cell death (apoptosis) of the host cell, similar to what is observed with Anaplasma phagocytophilum.
Subject: NC_004461:277291 Staphylococcus epidermidis ATCC 12228, complete genome
Lineage: Staphylococcus epidermidis; Staphylococcus; Staphylococcaceae; Bacillales; Firmicutes; Bacteria
General Information: This strain is a non-biofilm-forming, non-infection associated strain used for detection of residual antibiotics in food products. Common skin bacterium. Staphylcocci are generally found inhabiting the skin and mucous membranes of mammals and birds. Some members of this genus can be found as human commensals and these are generally believed to have the greatest pathogenic potential in opportunistic infections. This organism is the most prevalent and persistent Staphylococcus species on human skin. Has emerged as a common cause of nosocomial (hospital-acquired) infections, including catheter-associated infections and septicemia, particularly in immunocompromised patients. Resistant to many antibiotics including penicillins and cephalosporins.
