Title: Spirurina  
Author: World Heritage Encyclopedia
Language: English
Subject: Gongylonema neoplasticum, Nematode
Publisher: World Heritage Encyclopedia


Microfilariae of Mansonella perstans (left) and Loa loa (Spirurida: Filariidae)
Scientific classification
Kingdom: Animalia
Subkingdom: Eumetazoa
(unranked): Bilateria
Phylum: Nematoda
Class: Secernentea
Subclass: Spiruria

Camallanida (disputed)
Drilonematida (disputed)



Subclass Spiruria comprises mostly parasitic secernentean nematodes. In an alternate classification, they are treated as suborder Spirurina, with the orders listed here being ranked as infraorders.

The Ascaridida and the Oxyurida, which include worms that infect many mammals (including marine mammals), are sometimes placed in subclass Rhabditia. But that seems as spurious as the erstwhile placement of the Rhigonematida in subclass Tylenchia. The Camallanida and Drilonematida are sometimes included in the Spirurida as suborder and superfamily, respectively.[1]
