A serological survey was carried out in order to determine the prevalence of antirotavirus antibodies in Moroccan cattle under different management conditions. From the 493 serum samples examined, 325 (65.9%) were found positive, using a counter-immunoelectroosmophoresis technique. Animals of indigenous breed coming from farms with rapid turnover or large number of animals, or having frequent contacts with imported cattle, had a higher rate of seropositivity; however, positive sera were also found in cattle from small farms in remote areas, showing that rotavirus infection is ubiquitous in that country. No relationship was found between the prevalence of anti-rotavirus antibodies and the frequence of calf diarrhoea. The percentage of seropositive animals in a herd has to be considered as an epidemiological indicator.
为了确定不同管理条件下摩洛哥牛群中抗轮状病毒抗体的流行情况，开展了一项血清学调查。采用对流免疫电泳技术，在检测的493份血清样本中，有325份（65.9%）呈阳性。来自周转快或动物数量多的农场、或与进口牛频繁接触的本土品种动物，血清阳性率较高；然而，在偏远地区小农场的牛群中也发现了阳性血清，这表明该国轮状病毒感染普遍存在。未发现抗轮状病毒抗体的流行情况与犊牛腹泻频率之间存在关联。畜群中血清阳性动物的百分比应被视为一项流行病学指标。
