Actinomycosis

Clapis

Introduction

  • Bacterial disease in rabbits.
  • Cause:
    • Infection with Actinomyces spp Actinomyces spp.
    •  Actinomycesis a gram-positive filamentous bacteria.
    •  Actinomycesis facultatively anaerobic and grows best under anaerobic conditions.
  • Signs: formation of facial abscesses and uterine infection in rabbits.
  • Diagnosis: cytological examination, bacterial culture, histology.
  • Treatment: dependent on species, culture and sensitivity and often involves soft tissue and dental surgery plus prolonged antibiotic use.
  • Prognosis: depends on site of abscess, extent of infection and involvement of multiple bacteria.
  •  Actinomyces are part of the normal bacterial flora of the mucous membranes of mammals.
  •  Actinomyces colonize the periodontal mucosal surfaces. 
  • Pyogranluomatous infection occurs when endogenous Actinomyces, in addition to other bacteria, enter tissues.

Presenting signs

  • Most common presenting signs include facial abscesses.
  • Endometritis, metritis and pyometra Pyometra may be seen infrequently.

Sex predisposition

  • Males and females appear to be affected equally.

Public health considerations

  • There are no reports of the zoonotic potential of actinomycosis from clinically infected animals to humans.
  • As abscesses are associated with a number of bacteria strict hygiene is advised.
