We have identified a new group A rotavirus associated with diarrheic calves in the field. The VP7 gene of this virus (designated VMRI-29), appears to differ genetically from that of the reference strain NCDV-Lincoln. Studies are underway to determine the importance of this genetic variant in the etiology of rotavirus-induced calf diarrhea.
