Summary
An intensive study of 6 calves over a period of 14 months using viral isolation and serum neutralization techniques indicated that they were infected with a variety of enteroviruses and para-influenza 3 virus. Maternal antibody to infectious bovine rhinotracheitis and bovine viral diarrhoea viruses was present at one month. Active infection with these two viruses was not demonstrated during the course of the study.
