[Reverse plaque formation by hog cholera virus inducing interference with VSV (author's transl)].
Infection of PK15 cells with various strains of Hog Cholera (HCV, togaviridae) induces a transient refractory state to VSV. The reverse plaque procedure is convenient for HCV titration of virulent, "chronic" and attenuated strains.
