ABSTRACT
Winter dysentery is a bovine coronavirus (BCV)-caused disease that affects cows reported Europe, Japan, Canada and in the USA. The existence of enteric BCV infections in cows in an outbreak of diarrhea during the winter, a fact not reported in Brazil, has been surveyed in 9 stool samples with hemagglutination/ hemagglutination inhibition test and three were found positive. All 9 samples tested negative for rotavirus in PAGE. These results, the first description of BCV in adult cows in the Southern Hemisphere, show that winter dysentery also occurs in Southern, tropical areas and that BCV needs now to be considered in the aethiology of diarrheas in adult cattle in Brazil.
