Histopathology and Immunohistochemistry

Histopathology: Cyathocephalus truncatus is attached to the intestinal wall of Salmo trutta
Immunohistochemistry: Endocrin cells (arrows) in the epithelium immunoreactive to met-enkephalin-like peptide near the site of C. truncatus attacchment
Immunohistochemistry: Endocrin cells (arrows) containing a CCK-8-like substance in the tunica mucosa of the Leuciscus cephalus infected with Pomphorhynchu laevis (P)
