Interpretation Actinomycosis is a chronic, progressive, suppurative disease characterized by the formation of multiple abscesses, draining sinuses and dense fibrosis presenting as cervicofacial, thoracic, abdominal and pelvic infections. Microscopic examination of material from such sinuses often reveals sulfur granules, which are highly suggestive of Actinomyces infection. The differential diagnosis between actinomycosis and nocardiosis is relevant because treatment of each is different.
Collection Instructions See anaerobic cultures (Microbiology Procedures Section III-B-2) for proper collection.

Collect IUD in a sterile cup. On the requisition, write in a request for Actinomyces in the "Add to routine culture" portion of the Bacteriology Test Request section of the Microbiology Requisition.
Sample type Exudate or IUD
Stability Keep specimen in anaerobe collection tube and/or sterile cup at room temperature. Deliver as soon as possible. Drying of specimen will kill Actinomyces.
