Epidemiology

Habitat

  • Saprophytic; found in soil and plant debris.

Transmission

  • Inoculation at site of trauma, eg gunshot.

Pathological effects

  • Organisms sheltered from immune system by presence in granules within fistulous tracts.
  • May disseminate in immunosuppressed individuals.
  • Opportunistic; infection usually via direct inoculation, generally following trauma.
  • Usually localized skin infections; one report of bone infection.
  • Slow-growing subcutaneous mycetomas.
  • May spread beyond primary site.
  • Lesions composed of connective tissue with fistulae and pockets containing granular material.
  • Granules consist of colonies of organisms embedded in proteinaceous debris.

Control

Control via animal

  • Excision of mycetoma.
  • Often recur.

Control via chemotherapies

  • Antibiotic therapy in combination with excision.
  • Variable antibiotic sensitivity; carry out in vitro test.

Vaccination
