Infective endocarditis caused by non-HACEK Gram-negative bacteria is a microbiologically defined presentation with its own treatment requirements. This page outlines the clinical situation and points to the full structured protocol.
The specific scenario addressed here is infective endocarditis due to non-HACEK Gram-negative bacteria — a subset of endocarditis defined by the causative organism class, which drives the treatment strategy.
Evidence-based management in this setting involves early surgical intervention combined with prolonged bactericidal combination antibiotic therapy.
Recommended treatment is early surgery plus prolonged (6 weeks) therapy with bactericidal combinations of beta-lactams and aminoglycosides, sometimes with additional quinolones or cotrimoxazole.
