Secernentea
(Redirected from Secernentea Infections)
Secernentea is a class of nematodes, which are small, typically microscopic, parasitic worms. They are distinguished by having a specialized tubular excretory system with three canals. The Secernentea are further divided into two subclasses: the Rhabditia and the Spiruria.
Characteristics[edit | edit source]
Secernentea are characterized by their three-canal excretory system and a specialized stoma, or mouth, which is often surrounded by sensory structures called papillae. They also have a unique phasmid, a sensory organ, located near the posterior end of the body.
Subclasses[edit | edit source]
Secernentea is divided into two subclasses: Rhabditia and Spiruria.
Rhabditia[edit | edit source]
Rhabditia includes many free-living species as well as some parasitic ones. They are characterized by a rhabditoid pharynx, a type of muscular throat used for feeding.
Spiruria[edit | edit source]
Spiruria are primarily parasitic and are characterized by a spirurian pharynx. They often have complex life cycles involving multiple hosts.
Ecology[edit | edit source]
Secernentea species are found in a wide range of environments, from soil to fresh and salt water. Some species are parasitic, infecting a variety of hosts including humans, animals, and plants.
Medical relevance[edit | edit source]
Some Secernentea species are of medical and veterinary importance due to their parasitic nature. For example, species in the genus Strongyloides can cause strongyloidiasis, a disease in humans and other mammals.
