Spirurida is an order of spirurian nematodes. Like all nematodes, they have neither a circulatory nor a respiratory system.

Some Spirurida, like the genus Gongylonema, can cause disease in humans. One such disease is a skin infection with Spirurida larvae, called "creeping disease".

Systematics[edit]

The Camallanida are sometimes included herein as a suborder, and the Drilonematida are sometimes placed here as a superfamily. There are doubts about the internal systematics of the Spirurida, and some groups placed herein might belong to other spirurian or even secernentean lineages.[1]

The following superfamilies are at least provisionally placed in the Spirurida:
