Oral papillomatosis in two laboratory rabbits in Mexico
Abstract:
Oral papillomas were identified in two New Zealand white male rabbits from Mexico City. The growths were observed on the tip and ventral aspect of the tongue in a 3-year-old rabbit weighing 4 kg and on the tip of the tongue in a 15-month-old rabbit weighing 3.6 kg. Microscopic examination of the lesions revealed epithelial papillomas around fibrovascular stalks, and ultrastructural examination disclosed crystalline arrays of viral particles consistent with papova virus. This finding extends the known geographic distribution of the disease. Previous cases have been from the United States, The Netherlands, and Great Britain.
Insights
Oral papillomas caused by papova virus were found in two rabbits in Mexico City. This discovery expands the known geographic range of this rabbit oral disease.
Area of Science:
- Veterinary Pathology
- Virology
- Rabbit Medicine
Background:
- Oral papillomas are benign epithelial tumors that can affect rabbits.
- Papova viruses are known to cause papillomas in various animal species.
Observation:
- Two New Zealand white male rabbits from Mexico City presented with oral growths.
- Lesions were located on the tongue, specifically the tip and ventral aspect.
- One rabbit was 3 years old (4 kg) and the other was 15 months old (3.6 kg).
Findings:
- Microscopic examination confirmed epithelial papillomas surrounding fibrovascular stalks.
- Ultrastructural analysis revealed viral particles consistent with papova virus.
- This represents the first documented case of oral papillomas in rabbits from Mexico.
Implications:
- This finding extends the known geographic distribution of rabbit oral papillomas.
- Highlights the importance of considering papova virus in rabbit oral lesions.
- Contributes to understanding the global prevalence of this veterinary condition.
