(VK) and in Vero cell cultures under ordinary conditions (Vro) did not change essentially through passages in the trypsin-added Vero cell cultures (Vrt) from those of the original VK-grown virus . The 14th Vrt-passage virus was not transferable in Vro beyond two subpassages . Consequently, occurrence of adaptation to Vro during passages in Vrt can be excluded . Identification of V rt-grown virus as PI-4 was demonstrated by the cross neutralization and hemagglutination-inhibition tests performed among paramyxoviruses and b y several biological a nd physico-chemical tests. Other proteolytic enzymes , pancreatin d pronase, gave similar results as did trypsin, but hyaluronidase and lysozyme were ineffective . It was found that animal sera were inhibitory to the trypsin-effect mentioned above . Therefore, the Vrt system must be serum-free for obtaining reproducible results .
