Cetacean Morbillivirus: Current Knowledge and Future Directions
2014
We review the molecular and epidemiological characteristics of cetacean morbillivirus (CeMV) and the diagnosis and pathogenesis of associated disease, with six different strains detected in cetaceans worldwide. CeMV has caused epidemics with high mortality in odontocetes in Europe, the USAand Australia. It represents a distinct species within the Morbillivirusgenus. Although most CeMV strains are phylogenetically closely related, recent data indicate that morbilliviruses recovered from Indo-Pacific bottlenose dolphins (Tursiops aduncus), from Western Australia, and a Guiana dolphin (Sotalia guianensis), from Brazil, are divergent. The signaling lymphocyte activation molecule (SLAM) cell rec…
Emergence of the epibiotic barnacle Xenobalanus globicipitis in Guiana dolphins after a morbillivirus outbreak in Sepetiba Bay, Brazil
2021
Abstract We report on the emergence of the epibiotic barnacle Xenobalanus globicipitis in Guiana dolphins (Sotalia guianensis) from Sepetiba Bay, Rio de Janeiro, Brazil, in September 2018, six months after a lethal morbillivirus epidemic. Small boat surveys were conducted at the entrance and in the interior of the bay from January 2018 to February 2021. Dolphins were photo-identified and classified according to overall spatial use of the Bay. We examined the potential influence of the period and habitat on the prevalence of X. globicipitis. The overall prevalence of the barnacle was 38.7% in 214 dolphins. X. globicipitis was not observed in 99 individually identified dolphins from January t…
