MARMAM subscribers,

We would like to inform you of a paper recently published in PLoS One
regarding skin lesions on bottlenose dolphins from the southeastern U.S:

"Skin Lesions on Common Bottlenose Dolphins (Tursiops truncatus) from Three
Sites in the Northwest Atlantic, USA".

Abstract:
Skin disease occurs frequently in many cetacean species across the globe;
methods to categorize lesions have relied on photo-identification
(photo-id), stranding, and by-catch data. The current study used photo-id
data from four sampling months during 2009 to estimate skin lesion
prevalence and type occurring on bottlenose dolphins (*Tursiops truncatus*)
from three sites along the southeast United States coast [Sarasota Bay, FL
(SSB); near Brunswick and Sapelo Island, GA (BSG); and near Charleston, SC
(CHS)]. The prevalence of lesions was highest among BSG dolphins (*P = 0.587
*) and lowest in SSB (*P = 0.380*), and the overall prevalence was
significantly different among all sites (*p<0.0167*). Logistic regression
modeling revealed a significant reduction in the odds of lesion occurrence
for increasing water temperatures (*OR = 0.92; 95%CI:0.906–0.938*) and a
significantly increased odds of lesion occurrence for BSG dolphins (*OR =
1.39; 95%CI:1.203–1.614*). Approximately one-third of the lesioned dolphins
from each site presented with multiple types, and population differences in
lesion type occurrence were observed (*p<0.05*). Lesions on stranded
dolphins were sampled to determine the etiology of different lesion types,
which included three visually distinct samples positive for herpesvirus.
Although generally considered non-fatal, skin disease may be indicative of
animal health or exposure to anthropogenic or environmental threats, and
photo-id data provide an efficient and cost-effective approach to document
the occurrence of skin lesions in free-ranging populations.
