Effects of binary ethylenimine (BEI) treatment on the inactivation of infectivity and hemagglutinin of Newcastle disease virus (NDV) were studied in comparison with those of formalin treatment. Immune responses of chickens vaccinated with BEI- inactivated NDV vaccines were also investigated. Complete loss of infectivity of NDV (BI) was observed at 3, 7, and 24 hrs after the treatment at 37 deg C with BEI concentrations of 0.01M, 0.005M and 0.001M, respectively

A total of 10 colostrum-deprived pigs (1 or 2-day-old) and 6 pigs 35-day-old), which had been raised by natural maternal nursing, were used to study the pathogenicity of the porcine enteroviruses by the intracerebral and intramuscular routes of inoculation, which the enterovirus were isolated from the diseased pigs in Korea. The porcine enteroviruses produced an identical polioencephalomyelitis in colostrum-deprived pigs and 35-day-old pigs, which manifested clinical signs and histological changes. Clinically it was characterized by incoordination, rise in rectal temperature, ataxia, flaccid paralysis in all the experimental groups
