Schistosoma mansoni: immunohistochemical localization of the CHR reaction in glycocalyx of cercaria

Abstract Peroxidase-labeled baboon anti- Schistosoma mansoni gamma globulin was used to identify at the ultrastructural level the location of the Cercarienhullen (CHR) antigen-antibody reaction. The peroxidase label was localized in the tegumental glycocalyx of the cercariae of S. mansoni . These data constitute further evidence that the glycocalyx of the cercaria serves as the reaction site for the CHR.
