Suspected hypovitaminosis A in a colony of captive green anoles (Anolis carolinensis).

ABSTRACT

In a colony of 18 green anoles (Anolis carolinensis), 3 animals experienced focally thickened lips, ulcerative cheilitis, lethargy, depression, and weight loss over a 5-month period. In addition to crickets fed fresh fruit and leafy green vegetables, the diet of the green anoles consisted of a supply of mealworms that had been dusted with a commercial liquid vitamin supplement. The history, clinical findings, and histopathologic lesions were suggestive of hypovitaminosis A, which is known to cause squamous metaplasia of the mucus secreting glands and epithelial surfaces in many species.
