Neutralizing activity in isolated serum antibody fractions from visna-infected sheep

P D Mehta et al. Infect Immun. 1974 Sep.

Abstract

The neutralization technique was used to detect specific antibodies against visna virus in isolated immunoglobulin (Ig) G(1), IgG(2), and IgM fractions of visna-infected sheep serum. The neutralizing antibodies were present chiefly in the IgG(1) class. Low amount of activity was demonstrated in the IgM class, but no significant activity was seen in the IgG(2) class.
