| − | The term helminth is commonly used to describe parasitic worms, all with eukaryotic cell structures. The two main groups are the '''Nematodes''' (roundworms) and the '''Platyhelminthes''' (flatworms).[[Image:729px-Soybean cyst nematode and egg SEM.jpg|thumb|right|100px|Soybean cyst nematode and egg]]

| − | **Trematodes- commonly known as the 'flukes,' trematodes are non-segmented and have alternate sexual and non-sexual generations in different hosts. They are mostly hermaphroditic except the blood flukes, which are dioecious.

| − | **Cestodes- commonly known as the 'tapeworms,' these consist of an enlarged head section ('scolex'), with suckers or hooks for attachment in the intestine and successive flat segments forming a chain of 'proglottids'
