Contributor(s): Cathy Johnson-Delaney, David Perpinan

Introduction

  • Cause: infection with the bacteria Pseudomonas luteola.
  • Signs: dyspnea, coughing, lethargy, anorexia, fever, subcutaneous masses.
  • Diagnosis: fine needle aspirate, biopsy, radiography, ultrasonography, CBC and serum chemistries, thoracentesis.
  • Treatment: drainage of thoracic exudates, removal of infected lymph nodes, antibiotics, supportive/symptomatic treatment.
  • Prognosis: poor.

Pathogenesis

Etiology

  • Infection with Pseudomonas luteola bacteria.
  • Pseudomonas luteola is a motile, aerobic, gram-negative rod with yellow-orange pigmentation when grown on blood agar:
    • Frequently found in water, soil, and other damp environments.
    • It has a polysaccharide capsule and multitrichous polar flagella.

Pathophysiology

  • In humans, it may cause septicemia, peritonis and endocarditis when there is an underlying disease present.
  • The organism may also act as a nosocomial agent and infect critically ill patients that have had surgery or have indwelling devices inserted.
  • It has been associated with immunosuppressive therapy, chronic renal failure Renal failure and malignancy.
  • In ferrets, it has been linked with pyogranulomatous pleuropneumonia, mediastinitis and panniculitis.
  • Panniculitis is inflammation of the subcutaneous adipose tissue characterized by the development of single or multiple cutaneous nodules.

Timecourse

  • Acute dyspnea when infection involves the lungs.

Epidemiology

  • The infection in ferrets has only been reported recently in 6 cases in Europe.
