Neisseria pharyngis bacteriaemia in a patient with subacute bacterial endocarditis.

In September, 1955, a young woman of 21 was admitted to the National Heart Hospital with a clinical diagnosis of subacute bacterial endocarditis, involving the mitral valve. The illness developed a few weeks after a gum infection and the extraction of four teeth, in April. She had several attacks of tonsillitis before the age of 5 years, and at 7 heart disease was first nosed. At 16, in Ireland, she received penicillin for six weeks for bacterial endocarditis, from which she recovered.
