“…PPRV is placed in the genus Morbillivirus, subfamily Paramyxovirinae, family Paramyxoviridae and order Mononegavirales along with other members of the genus Morbillivirus: rinderpest virus (RPV), canine distemper virus (CDV), measles virus (MV) and cetacean morbilliviruses (CeMV) (Gibbs et al, 1979;Barrett, 1999). The host ranges for PPRV and RPV are probably identical and comprise members of the order Artiodactyla (Scott, 1964), whereas CD is reported to infect several families: Canidae, Mustelidae, Procyonidae, Felidae and Viverridae of the order Carnivora (Budd, 1981). Like other paramyxoviruses, PPRV is an enveloped virion (mean diameter of 400-500 nm), which contains a genome of singlestranded RNA with negative polarity (Fig.…”
