Helminths and Nematodes

Helminths and nematodes are worms that are often present in environments, including soil, fresh and salt water, and in and around animals and people. They are important because they are involved in decomposition, nutrient cycling and disease transmission, among other ecological roles. Helminths, in particular, are parasitic worms and some can cause diseases in humans, including schistosomiasis, hookworm, ascariasis and trichinosis. Nematodes, on the other hand, are beneficial to agriculture, as they help control insect pests, and can be used to break down organic matter and release nutrients. They have also been used as an experimental animal in a variety of scientific research areas.
