Abstract

Nocardia is a weekly staining gram-positive bacilli, forming partially acid-fast beaded branching filaments. Nocardia is found in soil rich in organic matter. They also form a part of oral microflora. Here, we report a case of oral nocardiosis in a 50-year-old male patient who was a known diabetic. He presented with painful swelling on the left side of the face since one year with intermittent pus discharge intra-orally. Incision and drainage was done for the abscess and pus was sent for routine culture and sensitivity, without suspecting nocardial infection. Gram stain of the pus showed numerous WBCs, occasional gram-positive cocci in clusters, and numerous filamentous gram-positive bacilli. Modified Ziehl-Neelsen stain of the pus sample showed acid-fast bacilli. Culture of the same yielded Nocardia asteroides (N. asteroides). The patient was treated with amikacin and amoxy-clavulanic acid to which he responded favourably.
