Klebsiella aerogenes, [2] previously known as Enterobacter aerogenes, is a Gram-negative, oxidase-negative, catalase-positive, citrate-positive, indole-negative, rod-shaped bacterium. [3] Capable of motility via peritrichous flagella, [ 4 ] it is approximately one to three microns in length.
Carbapenem-resistant Enterobacteriaceae (CRE) have been defined as carbapenem-nonsusceptible and extended-spectrum cephalosporin-resistant Escherichia coli, Enterobacter aerogenes, Enterobacter cloacae complex, Klebsiella pneumoniae, or Klebsiella oxytoca. Some exclude ertapenem resistance from the definition. [5]
Treatment options may include ... The first class C carbapenemase was described in 2006 and was isolated from a virulent strain of Enterobacter aerogenes. ...
Enterobacter is a genus of common Gram-negative, facultatively anaerobic, rod-shaped, non-spore-forming bacteria of the family Enterobacteriaceae. Cultures are found in soil, water, sewage, feces and gut environments.
ESCAPPM or ESCHAAPPM is a mnemonic for the organisms with inducible beta-lactamase activity that is chromosomally mediated. [1]E: Enterobacter spp. S: Serratia spp. C: Citrobacter freundii
Klebsiella is a genus of Gram-negative, oxidase-negative, rod-shaped bacteria with a prominent polysaccharide-based capsule. [3]Klebsiella is named after German-Swiss microbiologist Edwin Klebs (1834–1913).
The treatment of choice for HACEK organisms in endocarditis is the third-generation cephalosporin and β-Lactam antibiotic ceftriaxone. Ampicillin (a penicillin ), combined with low-dose gentamicin (an aminoglycoside ) is another therapeutic option.
Ceftolozane is an option for the treatment of complicated intra-abdominal infections and complicated urinary tract infections. It is combined with the β-lactamase inhibitor tazobactam , as multi-drug resistant bacterial infections will generally show resistance to all β-lactam antibiotics unless this enzyme is inhibited.
