Query: NC_013316:81969 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_002946:1786000 Neisseria gonorrhoeae FA 1090, complete genome
Lineage: Neisseria gonorrhoeae; Neisseria; Neisseriaceae; Neisseriales; Proteobacteria; Bacteria
General Information: A serum-resistant streptomycin-resistant proline-requiring strain isolated from a patient with disseminated gonococcal infections. Causes gonorrhea. One of two pathogenic Neisseria, this species causes the sexually transmitted disease (STD) gonorrhea, which is the leading reportable STD in adults in the USA. This human-specific organism colonizes and invades the mucosal surface of the urogenital epithelium, crosses the epithelial barrier, and ends up multiplying on the basement membrane. The Opa proteins are responsible for the opaque colony phenotype due to the tight junctions between adjacent Neisseria, and are also responsible for tight adherence to host cells. This organism, like Neisseria meningitidis, is also naturally competent for DNA uptake.
