Eimeria Kinsellai
''Eimeria kinsellai'' is an apicomplexan parasite of the genus ''Eimeria'' that infects the marsh rice rat (''Oryzomys palustris''). It was discovered in 1970 at Paynes Prairie, Alachua County Alachua County ( ) is a county in the north central portion of the U.S. state of Florida. As of the 2020 census, the population was 278,468. The county seat is Gainesville, the home of the University of Florida. History Prehistory and ear ..., Florida. A different ''Eimeria'', '' Eimeria palustris'', has been found in Alabama marsh rice rats. ''E. kinsellai'' differs from other ''Eimeria'' found in rice rats, such as '' Eimeria couesii'', '' Eimeria oryzomysi'', '' Eimeria ojastii'', and ''E. palustris'', in anatomical details. It was named after parasitologist John M. Kinsella.Barnard et al., 1971a, p. 547; Barnard et al., 1971b, p. 1294 References Literature cited *Barnard, W.P., Ernst, J.V. and Roper, R.A. 1971a.

Apicomplexa
The Apicomplexa (also called Apicomplexia; single: apicomplexan) are organisms of a large phylum of mainly parasitic alveolates. Most possess a unique form of organelle structure that comprises a type of non-photosynthetic plastid called an apicoplastwith an apical complex membrane. The organelle's apical shape is an adaptation that the apicomplexan applies in penetrating a host cell. The Apicomplexa are unicellular and spore-forming. Most are obligate endoparasites of animals, except '' Nephromyces'', a symbiont in marine animals, originally classified as a chytrid fungus, and the Chromerida, some of which are photosynthetic partners of corals. Motile structures such as flagella or pseudopods are present only in certain gamete stages. The Apicomplexa are a diverse group that includes organisms such as the coccidia, gregarines, piroplasms, haemogregarines, and plasmodia. Diseases caused by Apicomplexa include: * Babesiosis ('' Babesia'') * Malaria (''Plasmodium'') * Cr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parasite
Parasitism is a Symbiosis, close relationship between species, where one organism, the parasite, lives (at least some of the time) on or inside another organism, the Host (biology), host, causing it some harm, and is Adaptation, adapted structurally to this way of life. The entomologist E. O. Wilson characterised parasites' way of feeding as "predators that eat prey in units of less than one". Parasites include single-celled protozoans such as the agents of malaria, sleeping sickness, and amoebic dysentery; animals such as hookworms, lice, mosquitoes, and vampire bats; fungi such as Armillaria mellea, honey fungus and the agents of ringworm; and plants such as mistletoe, dodder, and the Orobanchaceae, broomrapes. There are six major parasitic Behavioral ecology#Evolutionarily stable strategy, strategies of exploitation of animal hosts, namely parasitic castration, directly transmitted parasitism (by contact), wikt:trophic, trophicallytransmitted parasitism (by being eaten), ...

Eimeria
''Eimeria'' is a genus of apicomplexan parasites that includes various species capable of causing the disease coccidiosis in animals such as cattle, poultry and smaller ruminants including sheep and goats. ''Eimeria'' species are considered to be monoxenous because the life cycle is completed within a single host, and stenoxenous because they tend to be host specific, although a number of exceptions have been identified. Species of this genus infect a wide variety of hosts. Thirty-one species are known to occur in bats (Chiroptera), two in turtles, and 130 named species infect fish. Two species (''E. phocae'' and ''E. weddelli'') infect seals. Five species infect llamas and alpacas: ''E. alpacae'', ''E. ivitaensis'', ''E. lamae'', ''E. macusaniensis'', and ''E. punonensis''. A number of species infect rodents, including ''E. couesii'', ''E. kinsellai'', ''E. palustris'', ''E. ojastii'' and ''E. oryzomysi''. Others infect poultry (''E. necatrix'' and ''E. tenella''), rabbits ('' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Paynes Prairie
Paynes Prairie Preserve State Park is a Florida State Park, encompassing a savanna in Alachua County, Florida lying between Micanopy and Gainesville. It is also a U.S. National Natural Landmark. It is crossed by both I-75 and U.S. 441 (which has a scenic outlook ramp). It is in the center of the Paynes Prairie Basin. The basin's primary source of drainage is Alachua Sink. During occasional wet periods, the basin will become full. A notable period occurred from 1871 to 1891 when the Alachua Sink was temporarily blocked. During this period, shallow draft steamboats were a frequent sight on Alachua Lake in the center of the prairie. The region was also historically known as the Alachua Savannah. Its drainage has been modified by several canals. Since 1927, Camps Canal has linked the basin to the River Styx which leads to Orange Lake and eventually the Atlantic Ocean through the St. Johns River. That reduced the basin's water intake by half. Additional changes to the prairie's e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alachua County
Alachua County ( ) is a county in the north central portion of the U.S. state of Florida. As of the 2020 census, the population was 278,468. The county seat is Gainesville, the home of the University of Florida. History Prehistory and early European settlements The first people known to have entered the area of Alachua County were Paleo-Indians, who left artifacts in the Santa Fe River basin before 8000 BC. Artifacts from the Archaic period (8000 - 2000 BC) have been found at several sites in Alachua County. Permanent settlements appeared in what is now Alachua County around 100 AD, as people of the wide-ranging Deptford culture developed the local Cades Pond culture. The Cades Pond culture gave way to the Alachua culture around 600 AD. The Timucua-speaking Potano tribe lived in the Alachua culture area in the 16th century, when the Spanish entered Florida. The Potano were incorporated by the colonists in the Spanish mission system, but new infectious diseases, reb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eimeria Palustris
