Induction of delayed-type hypersensitivity to staphylococcal antigens in guinea pigs.

Delayed-type hypersensitivity against staphylococcal antigens was induced in guinea pigs using Freund's incomplete as well as Freund's complete adjuvant. In animals sensitized with Freund's complete adjuvant the induction time and the duration of delayed-type hypersensitivity were longer and the skin reactions were stronger compared to animals sensitized with Freund's incomplete adjuvant. The difference between animals sensitized with Freund's incomplete or complete adjuvant may reflect the difference between tuberculin- and Jones-Mote type hypersensitivity.
