Abstract

The characteristics of a Newcastle disease virus isolated from a parrot (Psittacus erythracus) in Nigeria were examined using standard laboratory tests. Minimum lethal dose in embryos was 10−10, mean death time 44.8 h. The intracerebral and intravenous pathologic indices were 1.65 and 2.42, respectively. The virus was resistant at pH 3 and pH 7.2 and the hemagglutinin was thermostable at 56 C for 120 min. Of 10 mammalian species of erythrocytes examined, those of equine and rat were not agglutinated. The isolate was typed as a velogenic viscerotropic Newcastle disease virus.
