Haemophilus aphrophilus as a cause of chronic suppurative pulmonary infection and intra-abdominal abscesses.

A chronic Haemophilus aphrophilus pulmonary infection associated with the formation of intra-abdominal abscesses in a previously healthy 38-year-old man is described. Other reports have related the isolation of H. aphrophilus to underlying malignant disease or, when the cause of endocarditis, to pre-existing valvular disease. The underlying condition, if any, in this case remains unclear.
