Query: NC_013316:3056925 Clostridium difficile R20291, complete genome
Lineage: Peptoclostridium difficile; Peptoclostridium; Peptostreptococcaceae; Clostridiales; Firmicutes; Bacteria
General Information: Clostridium difficile R20291 was isolated in Stoke Mandeville Hospital, UK in 2006 and is closely related to the North American hypervirulent BI strains. Clostridium difficile, a Gram-positive, spore-forming anaerobic bacterium, is the leading cause of infectious diarrhea among patients in hospitals worldwide, causing C. difficile infection (CDI). An important nosocomial pathogen, it is frequently associated with antibiotic treatment and causes diseases ranging from antibiotic-associated diarrhea to life-threatening pseudomembraneous colitis.
Subject: NC_007799:284058 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.
