Query: NC_015702:2505633 Parachlamydia acanthamoebae UV7, complete genome
Lineage: Parachlamydia acanthamoebae; Parachlamydia; Parachlamydiaceae; Chlamydiales; Chlamydiae; Bacteria
General Information: This organism grows within Acanthamoeba spp., and uses these widespread ameobae as a replicative niche. They are the causal agents of severe upper respiratory infections in humans and animals. They are resistant to quinolones, antibiotics used to treat atypical pneuomonia.
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.
