Acute myocardial infarction associated with DF-2 bacteremia after a dog bite.

This is the first reported case of an acute myocardial infarction probably secondary to DF-2 bacterial septicemia and presumed endocarditis. Selective coronary arteriography revealed a long filling defect causing 95% stenosis of the second diagonal branch of the left anterior descending coronary artery. Multiple blood cultures revealed Decarboxylase Fermentor-2 (DF-2) septicemia that responded to penicillin therapy. Two months status after myocardial infarction recatheterization revealed complete recanalization with slight irregularity of the vessel lumen at the site of previous obstruction.
