Content: There is a naming convention which applies to all helminths: the ending "-asis" (or in veterinary science: " -osis") is added at the end of the name of the worm to denote the infection with that particular worm. For example, Ascaris is the name of a type of helminth, and ascariasis is the name of the infection caused by that helminth. Contents

Helminths are a group of organisms which share a similar form but are not necessarily related as part of evolution. The term "helminth" is an artificial term. There is no real consensus on the taxonomy (or groupings) of the helminths, particularly within the nematodes. The term "helminth" contains a number of phyla, many of which are completely unrelated. However, for practical considerations the term is currently used to describe four phyla with superficial similarities:
