Dear List members,
We are pleased to announce the publication of our paper.
Fury, C.A., and Reif, J.S. 2012. Incidence of poxvirus-like lesions
in two estuarine dolphin populations in Australia: Links to flood
events. Science of The Total Environment 416: 536-540.
Abstract: We report on the incidence of poxvirus-like lesions
assessed by photographic identification in two estuarine populations
of bottlenose dolphins (Tursiops aduncus) in Australia over a 3-year
period. Poxvirus infections of odontocetes are characterized by
pinhole or ring-like skin lesions that appear as solitary or
coalesced circular gray blemishes. Environmental and physiological
stressors are believed to contribute to their manifestation (Van
Bressem et al., 2009). A total of 187 boat-based surveys were
completed from October 2003 to September 2006 in the Clarence River
(CR) and Richmond River (RR) estuaries, with 720 dolphins sighted.
Forty-six individuals, including calves, were identified in the CR
and 23 in the RR. We investigated the temporal relationship between
four flood events that occurred in the region during the study period
and the occurrence of poxvirus-like skin lesions. Dolphin
poxvirus-like lesions were not observed in these populations prior to
2004. Following flood events in 2004, 2005 and 2006, a total of 10
new cases were observed, 6 in the CR and 4 in the RR. Our data
suggest that the occurrence of dolphin poxvirus-like lesions may be
an indicator for climatic events such as flooding. Long-term
follow-up of these estuarine populations is required to further
clarify the factors leading to 'outbreaks' of poxvirus infections.
