Study on the etiology of fibropapillomatosis of olive ridley sea turtles (Lepidochelys olivacea) nesting in the National Wildlife Refuge at Ostional, Guanacaste, Costa Rica

摘要: Sea turtle fibropapillomatosis is an emerging disease characterized by a proliferation of cutaneous papillomas, fibromas, and fibropapillomas occasional visceral fibromas. This paper aims to contribute the etiology in olive ridley sea turtles (Lepidochelys olivacea) nesting Ostional National Wildlife Refuge. Twenty-six with fibropapilloma were sampled 24 healthy served as controls. Biopsies taken tumors sick turtles, well skin biopsies from control subjects, blood samples collected all turtles. Tumorous microscopically analyzed order differentiate histological factors resulting pathogenesis, where main findings papillary epidermal hyperplasia, orthokeratotic hyperkeratosis, spirorchid-like eggs dermis, eosinophilic cytoplasmic inclusion. Hematology chemistry studies conducted on samples, MCHC, heterophils, lymphocytes, monocytes, AST, total protein, albumin globulin values significantly different between tumors. A PCR test was also determine presence herpesvirus papillomavirus possible etiologic agents, papilomavirus absent while present 69.23% tumors, this being most probable etiological agent fibropapillomatosis.
