Area of Science:

  • Veterinary Pathology
  • Microbiology

Background:

  • Actinobacillus lignieresii is a known bacterial pathogen.
  • It commonly causes 'wooden tongue' (lignieresii) in animals.

Observation:

  • Four cases of actinobacillosis presented with granulomas in atypical anatomical sites.
  • These unusual lesions were initially misidentified.

Findings:

  • The granulomatous lesions mimicked other conditions such as neoplasms, nasal polyps, and exuberant granulation tissue.
  • Microscopic examination confirmed Actinobacillus lignieresii as the causative agent.

Implications:

  • This highlights the importance of considering actinobacillosis in differential diagnoses for granulomatous lesions.
  • Accurate identification is crucial for appropriate treatment and management of affected animals.
