[en′tirōbaktir′ē·ā′si·ē]

Etymology: Gk, enteron + bakterion, small staff

a family of aerobic and anaerobic gram-negative bacteria that includes both normal and pathogenic enteric microorganisms. Among the significant genera of the family are Escherichia, Klebsiella, Proteus, and Salmonella.

Enterobacteriaceae [en″ter-o-bak-tēr″e-a´se-e]

a family of gram-negative, facultatively anaerobic, rod-shaped bacteria, usually motile, made up of saprophytes and plant and animal parasites of worldwide distribution, found in soil, water, and plants and in animals from insects to humans. In humans, disease is produced by both invasive action and production of toxin. Species not normally associated with disease are often opportunistic pathogens. Enterobacteriaceae have been responsible for as many as half of the nosocomial infections reported annually in the United States, most frequently by species of Escherichia, Klebsiella, Enterobacter, Proteus, Providencia, and Serratia.

Enterobacteriaceae

a family of gram-negative, rod-shaped bacteria (order Eubacteriales) occurring as plant or animal parasites or as saprophytes. Includes the lactose-fermenting genera of Escherichia, Enterobacter, Serratia and Klebsiella, and the apathogenic genera, Citrobacter and Erwinia. Also includes the nonlactose fermenters with pathogenic significance, Salmonella, Proteus and Yersinia.

Enterobacteriaceae

Microbiology A family of gram-negative, rod-shaped facultative anaerobic bacteria, most of which are motile–peritrichous flagella, oxidase-negative and have relatively simple growth requirements; Enterobacteriaceae are primarily saprobes, are widely distributed in nature in plants and animals, and are important pathogens; they are part of the intestinal flora, and popularly termed gram-negative rods–GNRs; they cause ±¹⁄₂ of all nosocomial infections in the US, most commonly by Escherichia, Enterobacter, Klebsiella, Proteus, Providentia, and Salmonella spp; less pathogenic Enterobacteriaceae include Citrobacter, Edwardsiella, Erwinia, Hafnia, Serratia, Shigella, Yersinia spp. See Citrobacter, Edwardsiella, Enterobacter, Erwinia, Escherichia, Hafnia, Klebsiella, Proteus, Providentia, Salmonella, Serratia, Shigella, Yersinia.
