Hassalstrongylus Musculi
''Hassalstrongylus musculi'' is a nematode worm of the genus '' Hassalstrongylus'' that infects the marsh rice rat (''Oryzomys palustris'') and house mouse (''Mus musculus'') in the United States and ''Oryzomys couesi'', ''Oligoryzomys fulvescens'', and '' Handleyomys melanotis'' in San Luis Potosí, Mexico. It was first described as ''Longistriata musculi'' by Dikmans in 1935, but transferred to ''Hassalstrongylus'' in 1971 and 1972 by Marie-Claude Durette-Desset. She later renamed the material she had used to describe ''H. musculi'' in 1972 as '' H. forresteri''. The females cannot be distinguished from those of the other species in the marsh rice rat, ''H. forresteri'' and '' H. lichtenfelsi''.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 ...

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 ...

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 commensalism, commensal in corn-cultivating communities. Weighing about , the marsh rice rat is a medium-sized rodent that resembles the common black rat, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
House Mouse
The house mouse (''Mus musculus'') is a small mammal of the order Rodentia, characteristically having a pointed snout, large rounded ears, and a long and almost hairless tail. It is one of the most abundant species of the genus '' Mus''. Although a wild animal, the house mouse has benefited significantly from associating with human habitation to the point that truly wild populations are significantly less common than the semi-tame populations near human activity. The house mouse has been domesticated as the pet or fancy mouse, and as the laboratory mouse, which is one of the most important model organisms in biology and medicine. The complete mouse reference genome was sequenced in 2002. Characteristics House mice have an adult body length (nose to base of tail) of and a tail length of . The weight is typically . In the wild they vary in color from grey and light brown to black (individual hairs are actually agouti coloured), but domesticated fancy mice and laboratory mice ar ...

Oryzomys Couesi
''Oryzomys couesi'', also known as Coues's rice rat, is a semiaquatic rodent in the family Cricetidae occurring from southernmost Texas through Mexico and Central America into northwestern Colombia. It is usually found in wet habitats, such as marshes, but also lives in drier forests and shrublands. Weighing about , ''O. couesi'' is a medium-sized to large rat. The coarse fur is buff to reddish above and white to buff below. The hindfeet show some specializations for life in the water, such as reduced ungual tufts of hair around the digits. It has 56 chromosomes. There is much geographic variation in size, proportions, color, and skull features. ''Oryzomys couesi'' is active during the night and builds nests of vegetation that are suspended among reeds about above the ground. It is an excellent swimmer and dives well, but can also climb in vegetation. An omnivore, it eats both plant and animal food, including seeds and insects. It breeds throughout the year; females giv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oligoryzomys Fulvescens

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 indigenou ...

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 Northeastern regions of the United States. It is bordered on the north and east by the state of New York; on the east, southeast, and south by the Atlantic Ocean; on the west by the Delaware ... 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. Parasitology, 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 Omnivore, omnivorou ...
