Molluscum contagiosum in three horses
Journal of the South African Veterinary Association
|June 1, 1991
Summary
Molluscum contagiosum, a viral skin disease, was diagnosed in horses in Zambia. The study details the slow-progressing lesions and microscopic findings of pox virions in affected animals.
Area of Science:
- Veterinary Dermatology
- Equine Pathology
- Viral Diseases
Background:
- Molluscum contagiosum is a human viral skin infection.
- This report details a suspected case in equine populations.
Observation:
- Three horses in Zambia presented with a slow-progressing skin disease.
- Lesions were observed on the chest, limbs, face, and body, varying in size (4-20mm).
- Lesions were hairless with keratin projections, bleeding when groomed, and had a depigmented, waxy appearance when older.
Findings:
- Microscopic examination revealed cytoplasmic inclusions containing pox virions.
- Virus culture attempts were unsuccessful.
Implications:
- This diagnosis expands the known host range for molluscum contagiosum-like viral infections.
- Highlights the need for veterinary surveillance of similar skin conditions in horses.
- Further research is needed to characterize the specific virus and its transmission.
