[Comparison of the biological properties of various strains of Aujeszky's disease viruses].
We compared three strains of Aujeszky's disease virus that had been isolated from slaughter pigs from the dormant foci of Aujeszky's disease, with the known virulent strain CVOS and TOP. No significant differences were found out in the following characters: titer value on tissue cultures from chick embryonal cells (KEB) and cellular line MDBK at the temperatures of 37 degrees C and 40 degrees C, cytopathogenic effect (CPE) in the HeLa cells, plaque formation in the KEB tissue culture, pruritus rise and the time of rabbit death after infection. Assessing the results of the comparison, the three new-isolated strains of Aujeszky's disease virus can be evaluated as strongly virulent.
