Query: NC_017056:804416 Rickettsia prowazekii str. BuV67-CWPP chromosome, complete genome
Lineage: Rickettsia prowazekii; Rickettsia; Rickettsiaceae; Rickettsiales; Proteobacteria; Bacteria
General Information: This species is the causal agent of typhus. The bacteria are transmitted via an insect, usually a tick, to a host organism, in this case humans, where they target endothelial cells and sometimes macrophages. They attach via an adhesin, rickettsial outer membrane protein A, and are internalized where they persist as cytoplasmically free organisms. Transovarial transmission (from mother to offspring) occurs in the invertebrate host.
Subject: NC_013316:120759 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.
