Endocarditis caused by Kingella denitrificans.

We report the case of a 48-year-old man with native valve endocarditis caused by Kingella denitrificans. He was successfully treated with a combination of beta-lactam antibiotics and aminoglycosides, after which he underwent valve replacement surgery. This case represents the first report in the literature of elective native valve replacement. Previously reported cases are discussed together with management options, including suggestions for the treatment of patients with beta-lactam allergy and those infected with beta-lactamase producing strains.
