A 63-year-old man with an aortic bioprosthetic valve was brought to the emergency room with altered mental status. Initial blood cultures revealed Gram-negative diplococci on Gram stain; echocardiogram showed a 5\u2005mm vegetation on the aortic bioprosthetic valve. The blood cultures grew<jats:italic>M. catarrhalis<\/jats:italic>and the patient was treated medically for prosthetic valve endocarditis with 6\u2005weeks of ceftriaxone and had a favourable clinical outcome.<jats:italic>M. catarrhalis<\/jats:italic>has a high prevalence of \u03b2-lactamase production and hence the patient was treated with ceftriaxone.
