Summary
A horse with a fractured jaw and osteomyelitis was diagnosed with Halicephalobus deletrix parasites. Parasitic migration to the brain and kidneys led to ataxia and euthanasia.
Area of Science:
- Veterinary Medicine
- Parasitology
- Equine Surgery
Background:
- A 13-year-old Quarter Horse presented with a chronic draining tract and hemimandibular fracture.
- The condition was complicated by pigmenturia and suspected renal abnormalities.
Observation:
- Radiography confirmed a mandibular fracture, tooth loss, and extensive osteomyelitis.
- Renal ultrasonography indicated a loss of normal architecture.
- Histopathology revealed granulomatous osteomyelitis and Halicephalobus deletrix parasites in the mandible.
Findings:
- The horse was treated with antimicrobials, deworming agents, and surgical debridement.
- Post-surgery, the horse developed ataxia, leading to euthanasia.
- Necropsy confirmed parasitic migration affecting the hemimandible, kidneys, and central nervous system (CNS).
Implications:
- This case highlights Halicephalobus deletrix as a potential cause of severe mandibular disease and systemic complications in horses.
- Early diagnosis and treatment are crucial, but parasitic migration poses a significant challenge.
- Further research into equine parasitic infections affecting the CNS and skeletal system is warranted.
