a genus of gram-negative, facultatively anaerobic, rod-shaped bacteria. A. hydro´phila causes cellulitis, wound infections, diarrhea, septicemia, and urinary tract infections. A. ca´viae and A. so´bia are found in fresh water and sewage and on fish, and cause gastroenteritis and wound infections in humans.
A genus of gram-negative, oxidase-positive, aerobic, facultatively anaerobic bacteria (family Vibrionaceae) containing rod-shaped to coccoid cells; motile cells ordinarily possess a single, polar flagellum; some species are nonmotile. The metabolism of these organisms is both respiratory and fermentative; nutritional requirements are not stringent. These bacteria are found in water and sewage; some are pathogenic to freshwater and marine animals, and to humans. Effects in humans include cellulitis; wound infections; acute diarrhea (especially caused by Aeromonas sobria); septicemia; urinary tract infection; hepatobiliary, meningeal, and auricular infections; and endocarditis. The type species is Aeromonas hydrophila.
AeromonasA genus of gram-negative, facultatively anaerobic, non-spore-forming bacilli, which have been isolated from various foods, including dairy products, meats and vegetables; Aeromonas spp may contaminate skin wounds and cause intestinal and extra-intestinal infections, including meningitis and sepsis in immunocompromised hosts.
A genus of aerobic, facultatively anaerobic bacteria (family Aeromondaccae) containing gram-negative, rod-shaped coccoid cells that occur singly or in pairs or in clumps of chains; motile cells ordinarily possess a single, polar flagellum; some species are nonmotile. The metabolism of these organisms is both respiratory and fermentative. These bacteria are found in water and sewage; some are pathogenic to fresh water and marine animals. The type species is A. hydrophila.
Genus of water-borne bacteria also found in sewage.
