👉 The term "helminthous" refers to a type of microorganism. Helminths are microscopic organisms that can cause diseases in humans and animals, such as roundworms (mitochondriophilic worms) and tapeworms (parasitic worms). These parasites transmit their life cycles through the feces of their hosts, where they feed on the host's waste products, which causes symptoms like nausea, vomiting, diarrhea, abdominal pain, and fever.
