For development of an animal model of virus-induced anergy, the effect of canine distemper virus (CDV) upon cell-mediated immunity in dogs was investigated. First, canine cutaneous reactions and in vitro lymphocyte responses to soluble protein antigens were characterized. Dogs immunized with picryl guinea pig albumin and with keyhole limpet hemocyanin (both in complete Freund's adjuvant) responded reproducibly to intracutaneous challenge with these antigens. Reactivity peaked in 20-40 days (maximal induration, 6-50 mm). Lymphocytes from these animals responded in vitro to stimulation with keyhole limpet hemocyanin or purified protein derivative. This stimulation was antigen-specific and was maximal on day 6 of culture. Infection with CDV depressed cutaneous reactivity and lymphocyte response in vitro to antigens and mitogens. This effect was transient in animals previously vaccinated with attenuated CDV; however, gnotobiotic puppies (susceptible to CDV) had prolonged depression of cell-mediated immunity and lymphopenia. Some of these animals developed neurologic symptoms and died. The findings indicate that CDV infection is a potentially useful model for study of virus-induced depression of T (thymus)-cell responses and support the hypothesis that there is more than one mechanism responsible for this phenomenon.
