Area of Science:

  • Veterinary Parasitology
  • Dermatology in Animals

Background:

  • Subcutaneous nodules and associated pyoderma were observed in an 11-year-old Cocker Spaniel.
  • Clinical signs included erythema, pyoderma, and draining fistulas from which purulent exudate could be expressed.

Observation:

  • An 11-year-old Cocker Spaniel exhibited subcutaneous nodules with erythema, pyoderma, and draining fistulas.
  • A large nematode, identified as Dracunculus insignis, was recovered from a nodular fistula.

Findings:

  • Isolation and identification of Dracunculus insignis from subcutaneous nodules in a canine patient.
  • Treatment with ivermectin, fenbendazole, and metronidazole proved ineffective in eradicating the parasite over a one-year period.

Implications:

  • This case highlights the diagnostic challenge of Dracunculus insignis infections in dogs.
  • The lack of treatment efficacy suggests potential resistance or difficulties in complete parasite removal, necessitating further research into effective therapeutic strategies for dracunculiasis in companion animals.
