Morbillivirus ecology in polar bears ( Ursus maritimus )

Polar Biology, 2000
Polar bear (Ursus maritimus) morbillivirus infection was initially reported by Follmann and co-workers in 1996, based upon serologic results using canine distemper virus (CDV). The impetus for the evaluation of polar bear populations for morbillivirus infections was prompted by epidemics of canine distemper-like disease in seal populations in the north
