Studies on the haemolytic property of some members of the paramyxo virus group

In the present work, a comparative study of the haemolytic activity of the three strains of different pathogenicity of NDV was carried out. These strains were the Velogenic strain (Farshout strain), the Meso[cnic 3train (Komarov strain) and the I..J(;D t.haemolysis. The hamolytic activity of mu~ps, pDrainfluuDz8-1 (Sendai strain) and parainfluenza-3 viruses with chickonerythrocytes has beeD also investiGated. In some aap.ic t s of this [ork, a study of t~12 rx.La tion- ship between haoDolysis, haemagglutination and elution was carried out. from r~sults G~prQsEed”J can point out to the fol~ow- ing conclusions :- 1- The m
