title: 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.
