Document Summary

Cestodes: phylum platyhelminthes, same as trematodes, class cestidea, common name tapeworm, order, cyclophyllidea, pseudophyllidea, all parasites, found in digestive track in the host, adult morphology. Pzq treatment preferentially damages tegument of neck: each section is called proglottid in different locations differ in development, gravid proglottid contain fully developed eggs, female and male organs develop in each proglottid monoecious, mature proglottids, male organs are going to form first protandry, develop and produce sperms, which are stored until the ovary matures, tapeworms are capable of self fertilization and cross fertilization, reproductive structure (figure 12 7, 12 8, reproduction, genital pore, cirrus male organ, vagina receives cirrus, ovary produces oocytes, oocytes move into oviduct, sperm fertilizes the oocyte in the oviduct zygote, vitelline glands contribute yolk and shell material, morphology, cyclo single, compact gland, pseudo scattered, zygote moves into ootype, ootype is surrounded by mehlis" gland, which secretes a thin membrane around the zygote and vitelline cells, from ootype, it passes into uterus.
