Enterobacteriaceae /En·tero·bac·te·ri·a·ceae/ (en″ter-o-bak-tēr″e-a´se-e) a family of gram-negative, rod-shaped bacteria (order Eubacteriales) occurring as plant or animal parasites or as saprophytes. Enterobacteriaceae [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´t n.pr a family of aerobic and anaerobic bacteria that includes both normal and pathogenic enteric microorganisms such as Escherichia, Klebsiella, Proteus, and Salmonella. 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.

Spread of novel expanded-spectrum [beta]-lactamases in Enterobacteriaceae in a university hospital in the Paris area, France. In three separate surveillance studies (E-0112, E-0115, E-0117) ceftobiprole was amongst the most potent cephalosporins against Enterobacteriaceae and Pseudomonas -- the most common Gram-negative bacterial pathogens associated with hospital-acquired infections -- explained in part by its enhanced affinity for the penicillin-binding protein 2 (PBP2) in pseudomonads (C1-0933). Conventional culture and speciation techniques tell us that the organisms typically associated with CSOM are Pseudomonas aeruginosa, Staphylococcus aureus, Staphylococcus epidermidis, Staphylococcus saprophyticus, Enterobacteriaceae spp. |
