Aeromonas A bacterial genus in the family Vibrionaceae comprising oxidase-positive, facultatively anaerobic, monotrichously flagellated gram-negative rods. The mesophilic species are A. hydrophila, A. caviae, and A. sobria; the psychrophilic one is A. salmonicida. Aeromonads are of aquatic origin and are found in surface and waste water but not in seawater. They infect chiefly cold-blooded animals such as fishes, reptiles, and amphibians and only occasionally warm-blooded animals and humans. Human wound infections may occur following contact with contaminated water. Septicemia has been observed mostly in patients with abnormally low white blood counts or liver disease. There is evidence of intestinal carriers. The three mesophilic species are also associated with diarrheal disease (enteritis and colitis) worldwide. See Diarrhea A related lophotrichous genus, Plesiomonas (single species, P. shigelloides), is also known as an aquatic bacterium and is associated with diarrhea chiefly in subtropical and tropical areas. It is also found in many warm-blooded animals. Systemic disease in humans is rare. See Medical bacteriology Aeromonas[e·rō′mōn·əs] (microbiology) A genus of bacteria in the family Vibrionaceae; straight, motile rods with rounded ends; most species are pathogenic to marine and fresh-water animals. Aeromonas
Aeromonas [a″er-o-mo´nas] 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.Aeromonas (ār-ō-mō'năs), 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.Aeromonas A 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.Aer·o·mo·nas (ār-ō-mō'năs) 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. Aer·o·mo·nas (ār-ō-mō'năs) Genus of water-borne bacteria also found in sewage. |
