Studies on recovery mechanism from rinderpest virus infection in rabbits. I. Effect of anti-thymocyte serum and thymectomy.
The role of cell-mediated immunity in recovery from rinderpest virus infection in rabbits was investigated by application of immunosuppressive procedures, i.e., treatment with anti-thymocyte serum and combined treatment with thymectomy and anti-thymocyte serum, both of which were confirmed to depress significantly cell-mediated immunity in rabbits. The immunosuppressed animals recovered in almost the normal fashion in terms of clinical signs, of virus clearance from the blood and lymphoid tissues and of repair of the lesions. It was suggested that the thymus-dependent cell-mediated immunity may not be essential in recovery from rinderpest virus infection. Possibility of participation of other recovery mechanisms was discussed.
