Immunolocalization of SjPrx-4 in eggs and adult worms of S. japonicum. The red arrows indicate the existence of SjPrx-4 expression. a The liver section from S. japonicum-infected mice reacted with anti-SjPrx-4 mouse serum shows immunopositivity in the space between the miracidium and the egg-shell. b There is no reaction in the liver section from S. japonicum-infected mice reacted with normal mouse serum. c Immunopositive reactions of SjPrx-4 were observed in the tegument (te) and in the parenchyma (p) of S. japonicum adult worms (♀: female and ♂: male). d The section from S. japonicum adult worms reacted with normal mouse serum did not reveal any immunopositive reactions.
