Is dolphin morbillivirus virulent for white-beaked dolphins ( Lagenorhynchus albirostris )?
The virulence of morbilliviruses for toothed whales (odontocetes) appears to differ according to host species. In 4 species of odontocetes, morbilliviruses are highly virulent, causing large-scale epizootics with high mortality. In 8 other species of odontocetes, including white-beaked dolphins ( La...
