Isolation of new serotypes of bovine rotavirus

Two cytopathogenic bovine rotavirus strains were isolated. The infectivity of both isolates was relatively stable at pH 3.0 and resistant to ether. Their replication was not affected by 5-iodo-2'-deoxyuridine. The new isolates shared immunofluorescent antigen with the Lincoln strain of bovine rotavirus. By neutralization test, however, these strains were clearly distinguished from one another.
