Enterobacter cloacae complex / Klebsiella aerogenes (formerly E. aerogenes) — Enterobacter cloacae complex / Klebsiella aerogenes

Review by an infectious diseases specialist in progress · edited by a physician, AI-assisted writing · level of evidence computed from the source type · page as of 29 October 2026 · Methodology

Enterobacteriaceae · Gram-negative

Attention aux céphalosporines de 3e génération : Enterobacter possède une céphalosporinase chromosomique inductible (AmpC). L'utilisation de C3G peut sélectionner des mutants déréprimés résistants en cours de traitement. La SPILF 2015 réserve les carbapénèmes aux situations sans alternative ; le choix définitif se fait sur l'antibiogramme (IDSA/ATS 2016).

Scope: dosing as described in the cited guidelines (French or international context, stated by the source), for adults with normal renal function unless stated on the line. No renal or hepatic, paediatric or pregnancy adjustment is provided systematically. These regimens have not been reviewed by any infectious-disease specialist to date.

Documented organ tropism

Organs where foci of Enterobacter cloacae complex / Klebsiella aerogenes (formerly E. aerogenes) are described in the cited literature. The reported frequency is not an individual probability.

Organ	Tropism	Level of evidence	Sources	Spread route
Urinary system / Bladder	High tropism	Evidence B	1	not recorded
Liver / Bile duct	High tropism	Evidence B	2	not recorded
Lung	Moderate tropism	Evidence B	1	not recorded
Colon / Alimentary system	Moderate tropism	Evidence B	2	not recorded

Described portals of entry

• Urinary system / Bladder
• Colon / Alimentary system
• Voies biliaires

Spread routes recorded: 0 of 4 documented foci A focus without a route is not a focus without spread: the route is simply not recorded.

Associated syndromes

• Urinary tract infection (UTI) (cystitis / pyelonephritis)
