Moraxella catarrhalis bacteraemia and prosthetic valve endocarditis
Type of Spiritual Experience
Endocarditis is inflammation of your heart's inner lining, called the endocardium. It's usually caused by bacteria. When the inflammation is caused by infection, the condition is called infective endocarditis. Endocarditis is uncommon in people with healthy hearts.

Moraxella catarrhalis bacteraemia and prosthetic valve endocarditis.
Shahani L1, Tavakoli Tabasi S2.
Moraxella catarrhalis, once considered a non-pathogenic coloniser of the oropharynx, has now been recognised as a true pathogen and is reported in cases of bacteraemia.
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 mm vegetation on the aortic bioprosthetic valve.
The blood cultures grew M. catarrhalis and the patient was treated medically for prosthetic valve endocarditis with 6 weeks of ceftriaxone and had a favourable clinical outcome. M. catarrhalis has a high prevalence of β-lactamase production and hence the patient was treated with ceftriaxone. This case highlights the importance of considering M. catarrhalis as a pathogen in cases of invasive disease.
