The epidemiology of peste des petits ruminants in the Sultanate of Oman.

Virological and serological evidence was obtained to show that peste des petits ruminants virus was widely distributed in Omani sheep and goats. There was no evidence for the concomitant presence of rinderpest virus in these species. Two virus isolates were classified as peste des petits ruminants virus on the basis of their pathogenicity in experimental animals and their specific hybridisation with nucleic acid probes. However, neutralisation tests and polyacrylamide gel analysis of their nucleocapsid proteins showed that they were not identical to the highly conserved African strains of this virus.
