Shell Lesion Management in Two Loggerhead Sea Turtles, Caretta caretta, with Employment of PC-7 Epoxy Paste

ABSTRACT Two loggerhead sea turtles, Caretta caretta, presented for carapace lesions characterized primarily by multiple small erosions. One individual had two deep lesions on the caudal carapace with complete loss of the keratin layer and exposure of underlying epidermis. Pump malfunction resulting in the development of an oily film on the surface of the turtles' tank was believed to have precipitated the lesions. Both turtles were treated with freshwater baths, topical povidone-iodine scrub, and systemic antibiotics with superficial lesions on both turtles healing. Deep lesions present on one animal persisted, however. Biopsy revealed an acute exudative epidermitis with fungal hyphae present throughout the exudative material. Topical disinfection and freshwater baths were employed as before. In addition, water-resistant dressings were placed over the lesions. Of the dressings tried, one involving the use of topical anti-infective drugs covered by a semiocclusive membrane and overlaid with PC-7 epoxy pas...
