Reports of lung abscess due to organisms not primarily causing pulmonary disease are relatively scarce. Such an abscess due to S. typhl harbouring a fungus ball is probably being reported for the first time. A young man of 28 years adequately treated for pulmonary tuberculosis presented with haemoptysis which was thought to be due to post - TB bronchiectasis. The sputum examination showed S. typhl in abundance and the serum Salmonella O and H titres were significantly high. The constitutional symptoms ameliorated after a course of antibiotics (chloramphenicol and ampicillin) and the antibody titres showed a drop. But, his haemoptysis persisted, though less in amount and warranted surgery in the form of left upper lobectomy. The patient has no symptoms presently and the sputum is negative for S. typhl.
