ACTINOMYCES-ODONTOLYTICUS THORACOPULMONARY INFECTIONS - 2 CASES IN LUNG AND HEART-LUNG TRANSPLANT RECIPIENTS AND A REVIEW OF THE LITERATURE

We present the first case of mediastinitis and the third case of pneum onia attributed to Actinomyces odontolyticus. The first patient presen ted 10 months after single-lung transplant with a subacute apical infi ltrate in the native lung and responded to therapy with oral penicilli n. The second patient developed pyogenic mediastinitis 25 days after a heart-lung transplant and required sternal debridement and intravenou s penicillin. We also review the literature on thoracopulmonary infect ions due to A odontolyticus.
