Fifteen bovine rotavirus group A strains were isolated in several Italian regions over the period 1981-1989 from calves in ten neonatal diarrhoea outbreaks. The electrophoretical analysis of the genoma showed genomic 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 possibility of simultaneous or sequential infection by more than one electropherotype or a modification in the length of RNA segments during infection.
1981年至1989年期间，在意大利的几个地区，从十起新生儿腹泻疫情中的小牛身上分离出了15株A组牛轮状病毒。基因组的电泳分析显示出基因组变异，观察到了五种不同的图谱，其中一种有13个双链RNA片段。相对于常规的11个基因组片段，发现额外的RNA片段表明可能存在由不止一种电泳型同时或相继感染的情况，或者在感染过程中RNA片段长度发生了改变。
