Immunological Studies On The Role of Cellular Immunity In The Protection of Rabbits Vaccinated With Some Bacterial Vaccines

The present study was carried out to throw spot lights on the rabbits as a model for evaluation of the cellular immunity in response to injection of some bacterial vaccines and because cell-mediated immune responses are best stimulated by live vaccines, BTwo experiments were carried out in two groups of rabbits. The first group used in evaluation of the cellular immunity of rabbits injected by BCG vaccine, and the other group used in evaluation of the cellular immunity of rabbits injected by Rev.l vaccineThe results of experiment I revealed that intradermal injection of BCG vaccine in the back of foreign and native (male and female) rabbits stimulated the output of viable lymphocytes in the peripheral blood up to the 3rd day post injection, where the tota
