Abstract

Serotoninergic and FMRFamidergic components of the nervous system were examined in cercaria from different types using immunocytochemical techniques interfaced with confocal scanning laser microscopy. Cercariae from 9 families were studied — Opisthorchis felineus, Parafasciolopsis fasciolaemorpha, Echinochasmus coaxatus, Echinoparyphium aconiatum, Notocotylus attenuatus, Psilotrema tuberculata, Plagiorchis sp., Cyathocotyle bithyniae, Diplostomum chromatophorum . The results show that 5-HT-IR and FMRFamide-IR occur in all types of cercariae, regardless of what morphological, taxonomic and biological group they belong to. Small differences in the patterns of 5-HT-IR and FMRFamide-IR were observed.
