Research Abstract

In order to protect against Apicomplexan parasites infection, tried to prepare the chicken monoclonal antibodies specific for them. In FY 2008, the cross-reactivity of chicken monoclonal antibodies against Crptosporidium was confirmed. In FY 21, monoclonal antibodies against apical complex which had been reported to be involved in protozoa invasion of host cells had cross-reactivities agains Eimeria spicies, in the 2010 final, ScFv recombinant antibodies were produced and had the cross-reactivities agains Apicomplexan parasites.
