In accordance with the lack of immunological studies concerning hares infected with EBHS virus, the aim of this study was to observe the dynamics of chosen indices of non-specific immunity altered with cidal capacity of PMN cells and the amount of lyzosyme in rabbits infected with EBHS virus. The studies were conducted to show replication of EBHS virus in the immune system in rabbits. The results of the studies in these animals have shown that EBHS virus replicates in rabbit’s cells, proving the brake through of the species barrier in rabbits, which during the course of this infection causes the activation of leucocytes resulting in an increased amount of LZM in serum.
