Cestodes

Cestodes are parasitic worms, known as tapeworms, which are commonly found in humans and animals. They are flat, segmented worms that can range in size from a few millimetres to several metres. They have a head, neck and a series of segments called proglottids. By attaching themselves to the intestine wall, cestodes absorb essential nutrients and can cause a variety of illnesses such as abdominal pain, diarrhoea and fatigue. Cestodes are the second most common group of parasitic worms, after roundworms. Humans can be infected with cestodes through the ingestion of food and water contaminated with eggs or larvae of the worm. Proper food hygiene and regular health check-ups are important in order to prevent cestode infection. Treatment for cestode infection involves taking medications to kill the worms.
