What are the classification of helminthology?
The major groups of parasitic helminths include: platyhelminths (flatworms), acanthocephalins (thorny-headed worms) cestodes (tapeworms), trematodes (flukes) and nematodes (roundworms).
Which disease is caused by helminth?
Helminths are parasitic worms. They are the most common infectious agents of humans in developing countries and produce a global burden of disease that exceeds better-known conditions, including malaria and tuberculosis.
How do helminths cause disease?
Helminths excrete into the intestine toxic substances after they feed. These substances then enter the circulatory and lymphatic systems of the host body. Chronic immune responses to helminthiasis may lead to increased susceptibility to other infections such as tuberculosis, HIV, and malaria.

Who discovered helminths?
The adult worms were discovered by Rudolf Virchow in 1859 (266) and Friedrich Zenker in 1860, and it was Zenker who finally recognised the clinical significance of the infection and concluded that humans became infected by eating raw pork (136, 281).
