Isolation of colonies from the mediastinal abscess following surgical incision, and microscopic view of isolates (the upper right panel, original magnification of × 1,000). All colonies are less than 0.5 mm in diameter with α-hemolysis and appear yellow with slightly gray areas in blood agar medium. Isolates were found to be short Gram-positive bacilli by microscopic study.
