Cestodes

Cestodes, commonly known as tapeworms, are flat, ribbon-like parasitic worms that live in the intestines of humans and animals. They attach to the intestinal wall using their scolex, which has hooks or suckers, and grow by producing segments called proglottids. These segments contain eggs, which are released into the host's feces and can contaminate food or water, potentially infecting others. Infections often occur through consuming undercooked or contaminated meat or fish. While some tapeworm infections cause mild symptoms, others can lead to nutritional deficiencies or more serious health issues if untreated.
