Elizabeth Randell Upton, R. P. Hanson, C. A. Brandly

Abstract

Seventeen heterologous combinations of Newcastle disease virus and antiserum have been used in serum neutralization tests. Of these combinations 13 exhibited a difference of greater than 1.0 log between the neutralization of the homologous and the heterologous virus by prepared antiserum. A difference of 5.0 logs was observed between 2 strains.
