ABSTRACT
An avian paramyxovirus-1, which was previously isolated from ailing fancy Columba livia in Saudi Arabia, was characterized in this study using monoclonal antibodies (Mabs). The results indicate that although the virus belongs to the pigeon paramyxovirus-1 (PPMV-1) group 'P' still it shows some variation in its binding pattern to the Mabs.

A comparative experimental study of the clinico-pathological and serological response of sheep and goats to orf infection was made. All infected animals depicted typical orf lesions and seroconverted. The clinical, serological, gross and histopathological responses were similar in both species. However, the disease span was longer in sheep than in goats. It was concluded that sheep could play an important role in maintenance of the virus in the environment.
