Abstract
Fifteen bovine rotavirus group A strains were isolated in several Ital ian regions over the period 1981-1989 from calves in ten neonatal diar rhoea outbreaks. The electrophoretical analysis of the genoma showed g enomic variations and five different profiles were observed, including one with thirteen dsRNA segments. The finding of extra RNA fragments, with respect to the regular eleven genome segments, suggests the poss ibility of simultaneous or sequential infection by more than one elect ropherotype or a modification in the length of RNA segments during inf ection.
