Mucocutaneous lesions in free-ranging Atlantic bottlenose dolphins Tursiops truncatus from the southeastern USA.

摘要: Mucocutaneous lesions were biopsied from free-ranging Atlantic bottlenose dolphins Tursiops truncatus inhabiting the Indian River Lagoon (IRL), Florida, and estuarine waters of Charleston (CHS), South Carolina, USA, between 2003 2013. A total 78 incisional biopsies 58 (n=43 IRL, n=15 CHS) examined. Thirteen had 2 at same examination, 6 re-examined re-biopsied time intervals varying 1 to 8 yr. Biopsy sites included skin (n=47), tongue (n=2), genital mucosa (n=29). Pathologic diagnoses were: orogenital sessile papilloma (39.7%), cutaneous lobomycosis (16.7%), tattoo disease (TSD; 15.4%), nonspecific chronic chronic-active dermatitis (15.4%), epidermal hyperplasia (12.8%). with predominately papillomas (n=9) (n=4), TSD (n=3), (n=1), (n=1). Persistent pathologic different times (n=2). This is first study documenting various types, combined prevalence, progression mucocutaneous in southeastern USA. The data support other published findings describing health patterns these geographic regions. Potential impacts related observed suite are important for IRL CHS dolphin populations, since previous studies have indicated that both populations affected by complex infectious diseases often associated immunologic disturbances anthropogenic contaminants.
