	Gyrinicola Batrachiensis ''Gyrinicola batrachiensis'' are nematode parasites that are members of the order Oxyurida. Members of this order are also known as pinworms. These organisms are nematodes that feed on micro-particles in the gut of vertebrates and invertebrates. Oxyurida is further separated into two superfamilies: Oxyuroidea and Thelastomatoidea, which are parasites of vertebrates and invertebrates respectively. Oxyuroidea is composed on three families: Pharyngodonidae; parasites of herbivorous vertebrates, and Oxyuridae and Heteroxynematidae; parasites of mammals and some birds. The life cycle of ''G. batrachiensis'' is generally simple and direct. Adult worms live in the posterior gut of the aquatic larval stage, or tadpole, of an anuran host. The females of this species produce two types of eggs: thick-shelled eggs and thin-shelled eggs, which are produced in separate uteri. Eggs deposited by females are passed through the hosts feces into the environment. Transmission occurs when infec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

	Spiruria 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.ToL (2002) Some important species Giant roundworm (''Ascaris lumbricoides''), causes ascariasis in humans ''Toxocara canis'', parasite of dogs ''Anisakis'', responsible for the human disease Anisakiasis ''Anisakis'' (a·nuh·saa·keez) is a genus of parasitic nematodes that have life cycles involving fish and marine mammals.

A similar species of ''Syphacia'' has been recorded from the rice rats ''Oligoryzomys fulvescens'' and ''Handleyomys melanotis'' in San Luis Potosí, but because only females were found, this worm could not be identified to species.Underwood et al., 1986 See also * List of parasites of the marsh rice rat A variety of parasites have been recorded from the marsh rice rat (''Oryzomys palustris''), a semiaquatic rodent found in the eastern and southern United States, north to New Jersey New Jersey is a state in the Mid-Atlantic and Northeaste ...

picture info	Nematode The nematodes ( or grc-gre, Νηματώδη; la, Nematoda) or roundworms constitute the phylum Nematoda (also called Nemathelminthes), with plant-Parasitism, parasitic nematodes also known as eelworms. They are a diverse animal phylum inhabiting a broad range of environments. Less formally, they are categorized as Helminths, but are taxonomically classified along with Arthropod, arthropods, Tardigrade, tardigrades and other moulting animalia, animals in the clade Ecdysozoa, and unlike platyhelminthe, flatworms, have tubular digestion, digestive systems with openings at both ends. Like tardigrades, they have a reduced number of Hox genes, but their sister phylum Nematomorpha has kept the ancestral protostome Hox genotype, which shows that the reduction has occurred within the nematode phylum. Nematode species can be difficult to distinguish from one another. Consequently, estimates of the number of nematode species described to date vary by author and may change rapidly over ...

	Secernentea Secernentea was a class of nematodes in the Classical Phylogeny System (Chitwood, 1958) and is no longer in use. This morphological-based classification system has been replaced by the Modern Phylogeny system, where taxonomy assignment is based on small subunit ribosomal DNA (SSU rDNA). Characteristics of Secernentea are: * Amphid apertures are pore/slit-like * Derids are present in some; located near nerve ring * Phasmids are present; posterior * Excretory system is tubular * Cuticle is striated in two to four layers; lateral field is present * Three esophageal glands; esophageal structure varies * Males generally have one testis * Caudal alae are common * Sensory papillae are cephalic only; may be caudal papillae in males * Mostly terrestrial * Rarely found in fresh or marine water Systematics Subclasses and orders of Secernentea are:Tree of Life Web Project (ToL) (2002)Nematoda.
