title: Search for shared antigens in the schistosome-snail combination Trichobilharzia ocellata-Lymnaea stagnalis.
abstract: Mother and daughter sporocysts of Tricholbilharzia ocellata, developing in the snail host Lymnaea stagnalis, were searched for substances with antigenic similarities to the snail's haemolymph. Antisera to cell-free snail haemolymph and fractions thereof were used in three different immunocytochemical staining methods, applied on sections of parasitized snails. Snail tissue was consistently stained; cercariae were stained, indicating that the applied methods were successful. Most sections through mother and daughter sporocysts were completely unstained. It is concluded that neither mother nor daughter sporocysts are masked by the antigens studied or substances mimicking these. The relevance of the present observations is discussed.
