Parelaphostrongylus tenuis (also known as meningeal worm or brainworm) is a neurotropic nematode parasite common to white-tailed deer, Odocoileus virginianus, which causes damage to the central nervous system.

Parelaphostrongylus tenuis, commonly called brain worm or meningeal worm, is a parasitic nematode (roundworm) that infects multiple species of hooved mammals.

Parelaphostrongylus tenuis is a metastrongylid nematode often referred to as brain worm or meningeal worm, given its location in vertebrate hosts. Adult nematodes are long and threadlike, with females up to 9 cm long X 0.25 mm wide.

Parelaphostrongylus tenuis is a parasitic nematode (roundworm) with a life cycle that involves white-tailed deer and several species of terrestrial snails and slugs in Eastern North America. P. tenuis is commonly referred to as “brainworm” or “meningeal worm.”

Parelaphostrongylus tenuis, commonly known as brain worm, is a nematode or roundworm parasite of white-tailed deer. The long, threadlike worms can be found in spaces and veins surrounding the brain. Adult male worms are greenish-yellow to brown in color and up to 6.2 cm (2.4 in) long and 0.2 mm (0.008 in) wide.

The adult brainworm (Parelaphostrongylus tenuis) is a roundworm or nematode normally found in the venous sinuses and subdural space of the brain of white-tailed deer in eastern North America. Moose, wapiti (elk), caribou, reindeer, mule deer, black-tailed deer, sheep, goats, and guinea pigs are susceptible to infection.

Parelaphostrongylus tenuis is a nematode parasite common to white tail deer. Sheep and goats, camelids, elk, caribou, and moose may be aberrant hosts. Adult worms in meningeal tissue lay eggs that develop into first stage larvae that migrate through the bloodstream to the lungs.

Parelaphostrongylus tenuis (i.e., meningeal worm) is a protostrongylid nematode parasite that rarely causes clinical disease in the definitive host, the white-tailed deer (Odocoileus virginianus). 12 However, when P. tenuis infects aberrant hosts, including domestic ungulates and other cervid species, it can migrate extensively through the ...

Mar 25, 2024 · Parelaphostrongylus tenuis is a major factor in moose population decline in the north-central United States and south-central Canada (Carstensen et al., 2017) and impedes translocations and reintroductions of caribou (Vors and Boyce, 2009), mule deer (Oates et al., 2000), and elk (Samuel et al., 1992). It also causes neurological symptoms and ...

Brain worm is the term commonly applied to the parasitic nematode (round worm), Parelaphostrongylus tenuis (P. tenuis). White-tailed deer are the normal host for this parasite. Most of the time, they are not affected by the parasite.

Parelaphostrongylus tenuis, also known as brainworm, is a neurotropic parasite commonly found in white-tailed deer, damaging their central nervous system. It infects other species like moose, elk, and caribou when their habitats overlap with high densities of white-tailed deer, leading to neurological instead of meningeal tissue infections.

Parelaphostrongylus tenuis, commonly called BRAIN WORM or meningeal worm, is a parasitic nematode (roundworm) that infects multiple species of hooved mammals. The WHITE-TAILED DEER serves as the definitive or natural host, meaning that worms are able to reproduce and lay eggs within the animal, and infected deer shed larvae in their feces.

Parelaphostrongylus tenuis (P. tenuis), commonly known as meningeal worm, is a nematode parasite of wildlife that spills over into domestic livestock, causing significant morbidity and mortality.

Brainworm (Parelaphostrongylus tenuis) Brainworm, also called meningeal worm, can cause moose to die due to impairment of their central nervous system. Brainworm is suspected to cause long-term decline in moose populations that occur in areas with abundant white-tailed deer. BrainwormLife Cycle . Deer and Brainworm

The meningeal worm, Parelaphostrongylus tenuis, cases neurologic disease that can result in death of llamas and alpacas. White-tailed deer are considered the natural definitive host for the meningeal worm but seldom show signs of infection.

Nov 30, 2020 · P. tenuis (aka meningeal worm, M-worm, or brain worm) is a parasitic nematode (roundworm) that, when accidentally ingested by an aberrant host (alpaca, llama, sheep, and goat), can cause serious neurologic disease and/or death.

Aug 15, 2024 · Meningeal worm (Parelaphostrongylus tenuis) is a parasite of white-tailed deer (WTD). As the natural host, they normally tolerate the parasite without exhibiting signs of disease.

Aug 26, 2023 · Meningeal worm (Parelaphostrongylus tenuis), also known as deer worm or brain worm, is a parasite of white tail deer that typically causes disease in sheep in the late summer and fall. In deer , the adult P. tenuis worms live on the membranes covering their …

The antemortem detection of a Parelaphostrongylus tenuis infection in a free-ranging wild elk (Cervus elaphus) in southern Ontario is documented. Postmortems on other free-ranging elk that died during 2000–2005 indicated that 59% (17/29) were ...

Parelaphostrongylus tenuis or brainworm is a small parasitic nematode that infects the brain of many ungulates. Its natural host, the white-tailed deer, is unaffected by its presence; other species, however, suffer severe neurological damage that eventually leads to death.
