Pterygodermatites Ondatrae
''Pterygodermatites ondatrae'' is a species of parasitic nematode in the genus ''Pterygodermatites''. It has been recorded in the hispid cotton rat (''Sigmodon hispidus'') in Florida and Texas. In Florida, it has also been recorded on the marsh rice rat (''Oryzomys palustris''), together with an unnamed species of the same genus, the female of which cannot be distinguished from that of ''P. ondatrae''.Kinsella, 1988, table 1 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 ...

Nematode
The nematodes ( or grc-gre, Νηματώδη; la, Nematoda) or roundworms constitute the phylum Nematoda (also called Nemathelminthes), with plant- 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 arthropods, tardigrades and other moulting animals in the clade Ecdysozoa, and unlike flatworms, have tubular 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 time.

Hispid Cotton Rat
The hispid cotton rat (''Sigmodon hispidus'') is a rodent species long thought to occur in parts of South America, Central America, and southern North America. However, recent taxonomic revisions, based on mitochondrial DNA sequence data, have split this widely distributed species into three separate species (''S. hispidus'', ''S. toltecus'', and ''S. hirsutus''). The distribution of ''S. hispidus'' ranges from Arizona in the west to Virginia to the east and from the Platte River in Nebraska in the north to, likely, the Rio Grande in the south, where it meets the northern edge of the distribution of '' S. toltecus'' (formerly ''S. h. toltecus''). Adult size is total length ; tail , frequently broken or stubbed; hind foot ; ear ; mass . They have been used as laboratory animals. Taxonomy The currently accepted scientific name for the hispid cotton rat is ''Sigmodon hispidus''. It is a member of the family Cricetidae.(Animal Diversity Web, University of Michigan Museum of Zool ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Florida
Florida is a state located in the Southeastern region of the United States. Florida is bordered to the west by the Gulf of Mexico, to the northwest by Alabama, to the north by Georgia, to the east by the Bahamas and Atlantic Ocean, and to the south by the Straits of Florida and Cuba; it is the only state that borders both the Gulf of Mexico and the Atlantic Ocean. Spanning , Florida ranks 22nd in area among the 50 states, and with a population of over 21 million, it is the third-most populous. The state capital is Tallahassee, and the most populous city is Jacksonville. The Miami metropolitan area, with a population of almost 6.2 million, is the most populous urban area in Florida and the ninth-most populous in the United States; other urban conurbations with over one million people are Tampa Bay, Orlando, and Jacksonville. Various Native American groups have inhabited Florida for at least 14,000 years. In 1513, Spanish explorer Juan Ponce de León became th ...

Marsh Rice Rat
The marsh rice rat (''Oryzomys palustris'') is a semiaquatic North American rodent in the family Cricetidae. It usually occurs in wetland habitats, such as swamps and salt marshes. It is found mostly in the eastern and southern United States, from New Jersey and Kansas south to Florida and northeasternmost Tamaulipas, Mexico; its range previously extended further west and north, where it may have been a commensal in corn-cultivating communities. Weighing about , the marsh rice rat is a medium-sized rodent that resembles the common black and brown rat. The upperparts are generally gray-brown, but are reddish in many Florida populations. The feet show several specializations for life in the water. The skull is large and flattened, and is short at the front. John Bachman discovered the marsh rice rat in 1816, and it was formally described in 1837. Several subspecies have been described since the 1890s, mainly from Florida, but disagreement exists over their validity. The Florida Key ...

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 and Kansas and south to Florida and Texas, and in Tamaulipas, far northeastern Mexico. Some of these parasites are endoparasites, internal parasites, while others are ectoparasites, external parasites. Parasitologist John Kinsella compared the endoparasites of marsh rice rats in a saltwater marsh at Cedar Key and a freshwater marsh at Paynes Prairie, both in Florida, in a 1988 study. He found a total of 45 species, a number unequaled in rodents. This may be related to the diverse habitats the rice rat uses and to its omnivorous diet; it eats a variety of animals which may serve as intermediate hosts of various parasites. The endoparasites in the saltwater marsh were dominated by trematodes (flukes), and those of the freshwater marsh by nematodes (roundworms). Endoparasites were found in th ...

Spirurida
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". Some species are known as eyeworms and infect the orbital cavity of animal hosts. Systematics 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.ToL (2002) The following superfamilies are at least provisionally placed in the Spirurida: * Acuarioidea * Aproctoidea * Diplotriaenoidea * Filarioidea * Gnathostomatoidea * Habronematoidea Habronematoidea is a superfamily of spirurian nematodes in the large order Spirurida.
