Morbillivirus infections in wildlife (in relation to their population biology and disease control in domestic animals).
The three members of the morbillivirus genus that infect wildlife in ecosystems where domestic animals occur are rinderpest, peste des petits ruminants (PPR) and canine distemper. Data on the relative susceptibility of species of the Order Artiodactyla for rinderpest have been obtained from historical records of outbreaks. Rinderpest in wildlife has only occurred in equatorial and eastern Africa since the great pandemic of 1889-1897. The distributions, densities and population dynamics of susceptible species in this region are described. There has only been one recorded outbreak of PPR in wildlife but the possibility of its occurrence in the future now that it is present in many parts of west and eastern Africa is discussed. Wild carnivora are not likely to be important maintenance hosts for canine distemper but the disease is of significance in free-ranging carnivores and particularly in small populations of endangered susceptible wildlife species. It is also of great significance in zoo populations.
