Clinical signs suggestive of canine distemper virus (CDV) infection we
re observed among a group of spotted hyaenas (Crocuta crocuta) in the
Serengeti, Tanzania. Virus antigen was detected immunohistologically i
n a brain sample from a diseased cub. The presence of virus RNA could
be demonstrated in this brain as well as in intestine and lymph node o
f the animal by RT-PCR. Sequence comparison of brain-derived amplicons
showed that the virus was related to recent CDV field isolates. The c
losest homology (> 99%) was to a recently described CDV which caused h
igh mortality in sympatric lions.
