Syphacia Oryzomyos
''Syphacia oryzomyos'' is a nematode that infects the marsh rice rat (''Oryzomys palustris'') in Florida. 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 and Kansas and south to Florida and Texas, and in Tamaulipas ...

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.

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 ...

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 ...

Oryzomyini
Oryzomyini is a tribe of rodents in the subfamily Sigmodontinae of the family Cricetidae. It includes about 120 species in about thirty genera,Weksler et al., 2006, table 1 distributed from the eastern United States to the southernmost parts of South America, including many offshore islands. It is part of the clade Oryzomyalia, which includes most of the South American Sigmodontinae. The name ''Oryzomyini'' derives from that of its type genus, ''Oryzomys'', which means "rice rat" or "rice mouse". Many species are also known as rice rats. Taxonomy Contents of Oryzomyini An oryzomyine group was first envisaged by Oldfield Thomas in the early 20th century. He defined it to include pentalophodont species, which have a mesoloph(id) on the upper and lower molars, with a long palate (extending past the third molars). Thomas included ''Oligoryzomys'', '' Oecomys'', and ''Oryzomys'' (which included many species now in other genera), as well as ''Rhagomys'', which is currently classi ...

Oligoryzomys Fulvescens
''Oligoryzomys fulvescens'', also known as the fulvous colilargo,Musser and Carleton, 2005 fulvous pygmy rice rat, or northern pygmy rice rat,Duff and Lawson, 2004 is a species of rodent in the genus ''Oligoryzomys'' of family Cricetidae. It is found from southern Mexico through Central America into South America, where it occurs south into Peru and Brazil, and includes numerous synonyms, including the type species of the genus, ''Oryzomys navus'' Bangs, 1899.

San Luis Potosí
San Luis Potosí (), officially the Free and Sovereign State of San Luis Potosí ( es, Estado Libre y Soberano de San Luis Potosí), is one of the 32 states which compose the Federal Entities of Mexico. It is divided in 58 municipalities and its capital city is San Luis Potosí City. Located in Central Mexico, San Luis Potosí is bordered by seven other Mexican states: Nuevo León to the north; Tamaulipas to the north-east; Veracruz to the east; Hidalgo, Querétaro and Guanajuato to the south; and Zacatecas to north-west. In addition to the capital city, other major cities in the state include Ciudad Valles, Matehuala, Rioverde, and Tamazunchale. History In pre-Columbian times, the territory now occupied by the state of San Luis Potosí contained parts of the cultural areas of Mesoamerica and Aridoamerica. Its northern and western-central areas were inhabited by the Otomi and Chichimeca tribes. These indigenous groups were nomadic hunter-gatherers. Although many indi ...

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 ...
