Establishment of adult Parelaphostrongylus tenuis, patent infections, and acquired immunity after experimental infection of white-tailed deer (Odocoileus virginicnms) and red deer (Cervus elaphus elaphus).
The meningeal worm, Parelaphostrongylus tenuis, a marginal limiting factor for moose, Alces alces in southern Quebec.
Typical causes of death included stress-related bacterial and viral infections, especially during the 2012 drought, as well as secondary conditions caused by neurologic disease (Parelaphostrongylus tenuis
Infrapopulation dynamics of Parelaphostrongylus tenuis

(1986) suggested Deroceras laeve was important in the transmission of Parelaphostrongylus tenuis
in central New Brunswick only because it was most heavily infected and most widespread; Rowley et al.
(Nematoda) and Fascioloides magna (Trematoda) in moose of southeastern Manitoba.
The co-occurrence of moose, white-tailed deer, and Parelaphostrongylus tenuis
Other contributing factors to the population increase were the reintroduction and spread of beaver (Castor canadensis) and corresponding increase in wetland habitat, and the decline of white-tailed deer (Odocoileus virginianus) populations and their associated parasite Parelaphostrongylus tenuis
(Alexander 1993, Bontaites and Guftason 1993).
However, current knowledge of the nature of moose declines and the biology of meningeal worm (Parelaphostrongylus tenuis
) makes this parasite the most credible explanation.
In addition to the absence of wolves (Canis lupus) and low levels of predation by black bear (Ursus americanus), disease and parasites present among moose populations in other regions, including Parelaphostrongylus tenuis
(brainworm) and Dermacentor albipictus (winter tick), appear to exist at low levels in the Cape Breton population.
Brainworm (Parelaphostrongylus tenuis
), a parasitic nematode commonly found in white-tailed deer (Anderson 1964), was discussed most because brainworm infection is commonly reported to cause mortality in moose.
This is usually related to "moose sickness" or parelaphostrongylosis as a result of the transmission of the nematode parasite, Parelaphostrongylus tenuis
, normally carried by white-tailed deer (Telfer 1967a,b; Peterson et al.
