Changes in Immune Globulin Levels in Horses with Infectious Anemia

Abstract

Four horses infected with equine infectious anemia maintained a high level of IgG during the observation period. In them the level of IgG (T) tended to decrease a little during this period.
Complement-fixation and precipitation antibodies became positive after the initial febrile attack. The former reached the highest titer immediately after the appearance and disappeared before long. The latter remained positive for a long time, at the end of which it reached the highest titer.
