Indices of non-specific immunity : an element of natural immunity in rabbits infected with RHD (rabbit haemorrhagic disease) virus

The paper describes non-specific immunity mediated by parameters of cell and humoral immunity in rabbits experimentally infected with seven haemagglutinating strains of the rabbit haemorrhagic disease (RHD) virus, including one which is an antigenic variant of RHDV, originating from various European countries and with a different isolation time. In addition to the studies performed earlier on different strains of RHDV, this paper also shows that the immunological differences between the strains may be the core of the existence of immunotypes among RHDV.
