title: Effect of antithymocyte serum on the course of chlamydial genital infection in female guinea pigs.
abstract: The treatment of female guinea pigs, infected in the genital tract with the chlamydial agent of guinea pig inclusion conjunctivitis, with rabbit anti-guinea pig thymocyte serum extended the course of the infection by 20 to 30 days. The rabbit anti-guinea pig thymocyte serum was shown to suppress delayed hypersensitivity responses to the guinea pig inclusion conjunctivitis agent and the contact allergen oxazolone. The appearance of antibody in genital secretions was delayed, but the infection persisted at low levels even when normal serum and secretory antibody titers were attained, indicating that cell-mediated immunity may play a role in the resolution of chlamydial genital infections.
