Secondary peritonitis by Actinomyces odontolyticus.

Abdominal actinomycosis is a rare infection and the non-recognition of this particular microorganism may led to a prolonged septic process and recurrent disease. We hereby present a case report of 53 years-old woman with a secondary peritonitis due to this microorganism and our option to perform a long course of penicillin derived antibiotics, after suture of a perforated gastric ulcer caused by a foreign body.
