Parasitology, the First Military Medical University, Guangzhou 510515 China. Clinical Lab., General Military Hospital, Guangzhou 510010 China. Sera from rabbits vaccinated mutiplly with ultraviolet-attenuated cercariae of Schistosoma japonicum were used to screen novel effective protective antigen against Schistosoma . Kda and so on were shown to be cross-reacted with both immunized sera and infected sera whereas immunized sera specifically recognized a SCA 104 KDa and a SCA 60 KDa antigen which showed an enhanced reactivity with immunized rabbit sera in comparison with infected rabbit sera. No SAWA antigen were recognized specially.
Further research is needed for the two potential protective antigen candidates.
