Enterobacter

Enterobacter

 [en″ter-o-bak´ter]

a genus of gram-negative, facultatively anaerobic, motile, rod-shaped bacteria. Organisms are widely distributed in nature and occur in the intestinal tracts of humans and animals. They are frequently a cause of nosocomial infections.

Enterobacter

(en'tĕr-ō-bak'tĕr),

A genus of aerobic, facultatively anaerobic, non-spore-forming, motile bacteria (family Enterobacteriaceae) containing gram-negative rods. The cells are peritrichous, and some strains have encapsulated cells. Glucose is fermented with the production of acid and gas. The Voges-Proskauer test result is usually positive. Gelatin is slowly liquefied by the most commonly occurring forms (Enterobacter cloacae). These organisms occur in the feces of humans and other animals and in sewage, soil, water, and dairy products; recognized as an agent of common nosocomial infections of the urinary tract, lungs, or blood; somewhat resistant to antibiotics. This genus characteristically acquires resistance rapidly in part because of the presence of inducible β-lactamases; the type species is Enterobacter cloacae.

Enterobacter

/En·tero·bac·ter/ (en´ter-o-bak″ter) a genus of gram-negative, facultatively anaerobic rod-shaped bacteria of the family Enterobacteriaceae, widely distributed in nature and occurring in the intestinal tract of humans and animals. Species including E. aero´genes, E. agglo´merans, E. cloa´cae, and E. gergo´viae, are frequently the cause of nosocomial infection, arising from contaminated medical devices and personnel.

Enterobacter

a genus of straight gram-negative rods, lactose-fermenting bacteria of the tribe Klebsielleae of the family Enterobacteriaceae. Found chiefly in the environment in water and soil but are common invaders of tissues in contaminated wounds of animals and in opportunistic infections such as cystitis and pyelonephritis in cattle. E. aerogenes (syn. Klebsiella mobilis) is occasionally a cause of bovine mastitis, uterine infections in mares and the mastitis-metritis-agalactia syndrome in sows.
