The Comparative Histochemistry Of The Infective Oncospheres Of Oochoristica Osheroffi Meggitt, 1934, And Oochoristica Scelopori Voge And Fox, 1950, (Cyclophyllidea: Linstowiidae) With Notes On The Origins Of The Egg Membranes, Gary R. Coulter
Loma Linda University Electronic Theses, Dissertations & Projects
Infective oncospheres of Oochorlstica osheroffi and Oochoristica scelopori were compared using fifteen histochemical tests. Vital stains were also used.
Carnoy’s-fixed gravid proglottids were vacuum-embedded in a paraffin-piccolyte mixture and cut transversely at 6 microns. Sections were tested for the presence of phosphatases, proteins, sclerotin precursors, nucleic acids, carbohydrates and acid mucopolysaccharides.
Oncospheres were histochemlcally very similar. Heavy concentrations of mucoproteins and glycoproteins were detected in the oncospheral coat of O. scelopori. Acid phosphatase was found in the embryophore of O. osheroffi, but could not be demonstrated in O. scelopori. No evidence of a sclerotized egg capsule was …
