ABSTRACT: We report on the epidemiology of lobomycosis-like disease (LLD), a
cutaneous disorder evoking lobomycosis, in 658 common bottlenose dolphins
Tursiops truncatus from South America and 94 Indo-Pacific bottlenose dolphins
T. aduncus from southern Africa. Photographs and stranding records of 387
inshore residents, 60 inshore non-residents and 305 specimens of undetermined
origin (inshore and offshore) were examined for the presence of LLD lesions
from 2004 to 2015. Seventeen residents, 3 non-residents and 1 inshore dolphin
of unknown residence status were positive. LLD lesions appeared as single or
multiple, light grey to whitish nodules and plaques that may ulcerate and
increase in size over time. Among resident dolphins, prevalence varied
significantly among 4 communities, being low in Posorja (2.35%, n = 85),
Ecuador, and high in Salinas, Ecuador (16.7%, n = 18), and Laguna, Brazil
(14.3%, n = 42). LLD prevalence increased in 36 T. truncatus from Laguna from
5.6% in 2007-2009 to 13.9% in 2013-2014, albeit not significantly. The disease
has persisted for years in dolphins from Mayotte, Laguna, Salinas, the
Sanquianga National Park and Bahía Málaga (Colombia) but vanished from the
Tramandaí Estuary and the Mampituba River (Brazil). The geographical range of
LLD has expanded in Brazil, South Africa and Ecuador, in areas that have been
regularly surveyed for 10 to 35 yr. Two of the 21 LLD-affected dolphins were
found dead with extensive lesions in southern Brazil, and 2 others disappeared,
and presumably died, in Ecuador. These observations stress the need for
targeted epidemiological, histological and molecular studies of LLD in
dolphins, especially in the Southern Hemisphere.Please feel free to contact me
if you have any enquiries.
