Abstract:
A virus isolated from the nasal secretions of a calf with acute respiratory disease was found to possess the general properties of rhinoviruses. Serologically it was related to the M-17 strain, a type 1 bovine rhinovirus, but distinct from the EC11 strain representing type 2. Seroconversion in neutralising antibody to the isolate was demonstrated in paired serum samples derived from the calf. This is the first report of bovine rhinovirus isolation in the Sudan and Africa. Whether bovine rhinoviruses play any significant role in bovine respiratory disease in the Sudan is not known and has yet to be determined.
