Granulomatous colitis associated with small strongyle larvae in a horse
Journal of the American Veterinary Medical Association
|September 1, 1984
Summary
Granulomatous colitis in horses, caused by small strongyles, presents diagnostic challenges with chronic weight loss and low fecal egg counts. Larva-cidal treatment with fenbendazole or ivermectin can be attempted for this condition.
Area of Science:
- Veterinary Medicine
- Equine Internal Medicine
- Parasitology
Background:
- Chronic weight loss in horses poses significant clinical management difficulties.
- Cyathostomiasis, specifically granulomatous colitis from mucosal stages of small strongyles, is an under-recognized cause of poor-doer horses.
Observation:
- Horses with this condition often exhibit weight loss, intermittent diarrhea, hypoalbuminemia, and elevated serum globulins.
- A key diagnostic challenge is the presence of low fecal egg counts, which can be misleading.
Findings:
- Diagnosis requires consideration of mucosal cyathostome stages in horses with characteristic clinical signs and low fecal egg counts.
- A case study detailing clinical and necropsy findings is presented to illustrate this condition.
Implications:
- Increased awareness of granulomatous colitis due to cyathostomes is crucial for accurate diagnosis and effective treatment of chronic weight loss in horses.
- Larva-cidal doses of fenbendazole or ivermectin represent potential treatment options for affected horses.
- Further research into diagnostic methods and treatment protocols for equine cyathostomiasis is warranted.
