Synonym(s): Corynebacterium pseudotuberculosis

Contributor(s): Catherine Fraser, Vetstream Ltd , Ben Dustan

Introduction

  • Cause: Corynebacterium pseudotuberculosis.
  • Signs: lymphangitis of lower limbs, excoriated nodules of lateral aspects of flanks, thorax, neck and face.
  • Diagnosis: direct smears.
  • Treatment: local treatment, possibly with surgical excision.
  • Prognosis: rarely fatal but long term disfigurement.
This is a rare condition of cattle.

Pathogenesis

Etiology

  • This is a rare condition of cattle.
  • The causative bacteria is Corynebacterium pseudotuberculosis Corynebacterium pseudotuberculosis.
  • Other bacteria can be present either alone or in mixed infections and occasionally cultures are negative.
  • Gains access via skin wounds.

Predisposing factors

General

  • Poor hygiene and skin abrasion. 
  • Skin abrasion are often a result of poor Cubicle design Cubicle design and maintenance and as such this may present as a herd problem.
  • Insect transmission Insect transmission (biting flies).

Pathophysiology

  • Infection of the cutaneous lymphatics of the lower limbs and feet also neck, shoulders and flanks leads to:
    • Local edema and fibrosis.
    • Cording of the lymphatics.
    • Nodules develop which may be soft or hard.
    • Cyclical abscessation and discharge.
    • Ulceration and draining tracts.

Timecourse

  • Individual abscesses resolve over 1-2 weeks but more break out leading to a protracted timecourse.

Epidemiology

  • Poor hygiene, resulting in contaminated skin, is a prerequisite to allow the infection to spread.
  • Once infection is established, then insect transmission may transfer the infection between animals.
