Two independent experiments were conducted with broilers to determine the effect of threonine and vitamin A on immune system. In first experiment, dietary treatments contained 0.8%, 0.87%, 0.94 % and 1.01 % total threonine. In second experiment, diets were as follows: basal diet without vitamin A; basal diet plus 1500 IU/Kg vitamin A; basal diet plus 6250 IU/Kg vitamin A; basal diet plus 11000 ...

A cutaneous basophil hypersensitivity response has been observed in rabbits immunized with bovine serum albumin and challenged intradermally with this antigen 7 days later. The cellular response appears to be similar to cutaneous basophil hypersensitivity reported in guinea pigs and humans. A basophil response was also observed in rabbits immunized with Staphylococcus aureus and challenged with...

Delayed onset erythematous skin reactions elicited in guinea pigs early in the course of sensitization with azobenzenearsonate-protein conjugates or with protein antigens in incomplete Freund's adjuvant or in saline were found to have a characteristic morphology which sets them apart from delayed hypersensitivity and the classic antibody mediated reactions. The principle feature was massive der...

Guinea pigs immunized with protein antigens emulsified with complete Freund's adjuvant (CFA) and skin tested at 3-4 wk have classical tuberculin-type delayed hypersensitivity (DH) reactions with few basophils present. However, recipients of T cells from these animals have delayed responses containing large basophil infiltrates and thus resemble basophil-rich cutaneous basophil hypersensitivity ...

Jones-Mote reactions are delayed, erythematous, and mildly indurated cutaneous reactions originally described in humans sensitized by skin injection of heterologous proteins. Similar reactions in guinea pigs contain many basophils and are called cutaneous basophil hypersensitivity. In contrast, guinea pigs immunized with mycobacterial adjuvants have classical tuberculin-type delayed hypersensit...
