The study was carried out to detect group- and subgroup-specific antigens o
f bovine rotaviruses. Stool specimens, collected from diarrhoeic calves of
the Savar Dairy Farm, Bangladesh, were examined by an enzyme-linked immunos
orbent assay, using group- and subgroup-specific monoclonal antibodies. Thi
rty-three specimens showed specificity for group A rotavirus. While subgrou
ping, 21 group A-positive specimens showed subgroup I specificity. Twelve s
pecimens did not react with either of the subgroup I- and subgroup II-speci
fic monoclonal antibodies.
