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.
