Identification and properties of Aerococcus viridans isolated from the blood of a patient with infectious endocarditis are described. The role of this agent in the pathogenesis of this disease was demonstrated by repeated cultivations as well as by high titres of specific antibodies in the patient's serum. Pathogenicity of this strain for experimental animals was not demonstrated.
