What organisms are Enterobacteriaceae?
The Enterobacteriaceae are a large family of bacteria, including many of the more familiar pathogens, such as Salmonella, Shigella and Escherichia coli. Members of the Enterobacteriaceae are bacilli (rod-shaped), facultative anaerobes, fermenting sugars to produce lactic acid and various other end products.
What is Enterobacteriaceae PDF?
Enterobacteriaceae is a family of Gram-negative, facultatively anaerobic, non-spore-forming rods. Characteristics of this family include being motile, catalase positive, and oxidase negative; reduction of nitrate to nitrite; and acid production from glucose fermentation.
What is the scientific name of Enterobacteriaceae?

What are Enterobacteriaceae? Enterobacteriaceae are a large family of Gram-negative bacteria that includes a number of pathogens such as Klebsiella, Enterobacter, Citrobacter, Salmonella, Escherichia coli, Shigella, Proteus, Serratia and other species.
What causes Enterobacter infection?
Enterobacter UTI can present with dysuria, frequency, urgency, and positive leukocyte esterase or nitrites on urinalysis. Risk factors that predispose to infection include the following: Prolonged recent use of antimicrobial treatment. Immunocompromised states, particularly malignancy and diabetes.
How is Enterobacteriaceae treated?
The antimicrobials most commonly indicated in Enterobacter infections include carbapenems, fourth-generation cephalosporins, aminoglycosides, fluoroquinolones, and TMP-SMZ. Carbapenems continue to have the best activity against E cloacae, E aerogenes, (now known as Klebsiella aerogenes) and other Enterobacter species.
What does Enterobacteriaceae cause?
Enterobacter species are responsible for causing many nosocomial infections, and less commonly community-acquired infections, including urinary tract infections (UTI), respiratory infections, soft tissue infections, osteomyelitis, and endocarditis, among many others.
How do you get Enterobacter infection?
The source of infection may be endogenous (via colonization of the skin, gastrointestinal tract, or urinary tract) or exogenous, resulting from the ubiquitous nature of Enterobacter species.
Where does Enterobacter come from?
Enterobacter is named for the organisms’ predominant natural habitat, the intestines of animals (from Greek enteron, meaning “intestine”). Enterobacter are ubiquitous in nature; their presence in the intestinal tracts of animals results in their wide distribution in soil, water, and sewage.
How is Enterobacter treated?
Possible treatments include carbapenems, beta-lactams, beta-lactamase inhibitors, fluoroquinolones, aminoglycosides, and sulfamethoxazole/trimethoprim. First and second-generation cephalosporins are generally not effective against Enterobacter infections.
How do you get Enterobacter?
How is Enterobacter cloacae transmitted? Immunocompromised Patients are at risk if they come into direct or indirect contact with contaminated persons or objects. The pathogens can also be transmitted via contaminated infusion solutions or blood products.
