18 strains of viruses which replicated with cytopathic effect in cell line BTR (bovine trachea) were isolated from the faeces of convalescent and diarrhoeal calves at the age of 1-3 months. The cytopathic effects were characteristic for enteroviruses. These lesions appeared after the second day following infection with the BTR, and the maximum level of virus was 10E-6 - 10E-7 TCID sub(50)/0.1 ml. In the electron microscope the isolates have a cubic symmetry (diameter 20-30 nm). On the basis of their morphology, resistance to chloroform and lack of replication inhibition by 5-iodine-2'desoxyuridine (IUDR) the isolated strains were classified in the enterovirus group
