*The isolation and identification of Actinomyces can confirm a diagnosis of Actinomycosis.
*The most common clinical specimens employed in isolation are samples of pus, tissue, or sulphur granules
*Cultures are positive between the 7th and 21st day when grown anaerobically at 37C.
===Histopathology===
*Demonstration of gram positive filamentous organisms and sulphur granules on histological examination is strongly supportive of a diagnosis of actinomycosis.
*Although the presence of sulphur granules is helpful in making the diagnosis, they are not always recovered in culture confirmed cases of actinomycosis.

Overview

Laboratory findings

The gold standard for diagnosing actinomycosis is histological examination and bacterial culture.

CBC

Findings are non-specific and include

  • Anemia with mild leucocytosis
  • Elevated ESR, and CRP
  • Elevated Alkaline phosphatase in hepatic actinomycosis

Culture

  • The isolation and identification of Actinomyces can confirm a diagnosis of Actinomycosis.
  • The most common clinical specimens employed in isolation are samples of pus, tissue, or sulphur granules
  • Cultures are positive between the 7th and 21st day when grown anaerobically at 37C.

Histopathology

  • Demonstration of gram positive filamentous organisms and sulphur granules on histological examination is strongly supportive of a diagnosis of actinomycosis.
  • Although the presence of sulphur granules is helpful in making the diagnosis, they are not always recovered in culture confirmed cases of actinomycosis.
