[Dynamics of homocytotropic antibody production in pigs].

Homocytotropic antibody (HTA) production in pigs was stimulated by sensitization with alum precipitated equine serum or with equine serum in Freund's complete adjuvant. Two doses of appropriate antigen were given in 7 days interval simultaneously with heat inactivated suspension of Bordetella pertussis organisms. HTA were detected in 6 of 10 pigs sensitized with alum precipitated serum and in 4 of 6 pigs sensitized with serum in Freund's complete adjuvant.
