Query: NC_008555:2628858 Listeria welshimeri serovar 6b str. SLCC5334, complete genome
Lineage: Listeria welshimeri; Listeria; Listeriaceae; Bacillales; Firmicutes; Bacteria
General Information: Nonpathogenic bacterium. This organism is a nonpathogenic Listeria found in soil, water, food, and sewage. First isolated from decaying plants. L. welshimeri bacteria are small (0.5 to 2.0 μm), non-spore-forming, gram-positive rods which are motile below 30°C by means of peritrichous flagella.
Subject: NC_007799:392355 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.
