ABSTRACT
A high incidence of enteroviruses isolated by the use of bovine kidney cell cultures has been found in rectal swabs from normally reared calves. In no case were enteroviruses recovered from calves less than 4 wk of age. Only one of seven parturient cows was shown to be shedding enteroviruses.
Two ether-resistant virus types were identified which differed in serologic specificity, characteristics of plaque formation in bovine kidney cell cultures, and in vitro host range. The incidence of these types of enteroviruses could not be correlated with the appearance of clinical signs in these calves.
