parelaphostrongylus tenuis in new brunswick: the parasite in white-tailed deer (odocoileus virginianus) and moose (alces alces).research was initiated in 1983 to investigate the ecology of parelaphostrongylus tenuis in new brunswick. the objectives were to determine the prevalence and intensity of infection in white-tailed deer, and to determine whether or not moose feces contained first stage larvae, signifying the completion of the life cycle of p. tenuis in this host. forty-nine percent of deer pellet samples were positive and 60% of deer heads contained adults of p. tenuis. none of the moose pellet samples contained ...19873682097
experimental infection of mule deer with parelaphostrongylus tenuis.six adult and three fawn mule deer (odocoileus hemionus) were experimentally infected with a range of 75-100 infective larvae of parelaphostrongylus tenuis. five of the six adult deer developed clinical signs of neurologic disease that terminated in paralysis between 35 and 80 days. the sixth deer developed slight signs of neurologic disease for 10 days, but recovered. all three mule deer fawns developed neurologic disease. adult meningeal worms were recovered from the subdural space of the spin ...19807463606
parelaphostrongylus tenuis in maine moose and the possible influence of faulty baermann procedures.efficacy of cleaning baermann apparati was evaluated to determine if larvae are retained on glassware after evaluating white-tailed deer (odocoileus virginianus) fecal samples containing parelaphostrongylus tenuis. residual p. tenuis larvae were recovered from 7 (11.7%) of 60 baermann apparati cleaned with soap and tap water. of 295 moose (alces alces) fecal samples collected in central and northern maine, only one contained protostrongylid larvae. our data do not support the hypothesis that rec ...19938445780
low-dose meningeal worm (parelaphostrongylus tenuis) infections in moose (alces alces).parelaphostrongylosis has a rapid onset and is lethal in neonatal moose (alces alces) when large numbers of third-stage parelaphostrongylus tenuis larvae (l3) are given experimentally. little is known, however, about the severity and prognosis of infections acquired naturally by accidentally ingesting terrestrial gastropods which are rarely infected and have few larvae. to investigate the relationship between infecting dose, age of moose, and severity of disease, five calves were given low doses ...200212528448
detection of anti-parelaphostrongylus tenuis antibodies in experimentally infected and free-ranging moose (alces alces).confirming parelaphostrongylus tenuis infection in moose (alces alces) and other susceptible hosts is difficult. an enzyme-linked immunosorbent assay (elisa) was developed using the excretory-secretory (es) products of third-stage p. tenuis larvae (es-elisa) and the test applied to serum samples obtained from seven moose calves (5-9.5 mo old) given infective larvae (l3) in doses approximating those likely to be received in nature (3-30 l3). anti-p. tenuis immunoglobulin g antibodies were detecte ...200212528449
nova scotia moose mystery--a moose sickness related to cobalt- and vitamin b12 deficiency.a wasting, debilitating disease with uncertain aetiology affecting moose (alces alces americana) in eastern north america has been reported repeatedly ever since the 1910s. despite the intensive studies during 1930-1960s the cause of the sickness could not be established. in the 1960s a parasitic nematode (parelaphostrongylus tenuis) was reported as constituting a probable explanation for the sickness, although several clinical and pathological signs remained unexplained. in sweden, a moose dise ...200414654277
landscape influence on spatial patterns of meningeal worm and liver fluke infection in white-tailed deer.parasites that primarily infect white-tailed deer (odocoileus virginianus), such as liver flukes (fascioloides magna) and meningeal worm (parelaphostrongylus tenuis), can cause morbidity and mortality when incidentally infecting moose (alces alces). ecological factors are expected to influence spatial variation in infection risk by affecting the survival of free-living life stages outside the host and the abundance of intermediate gastropod hosts. here, we investigate how ecology influenced the ...201525498206
necropsy findings in 62 opportunistically collected free-ranging moose (alces alces) from minnesota, usa (2003-13).the minnesota, us moose population has declined dramatically since the 1990s. all 54 carcasses of moose that died of unknown cause or were euthanized by gun shot by tribal or department of natural resources personnel because of perceived signs of illness between 2003 and 2013 and eight carcasses of moose that died from vehicular accidents between 2009 and 2013 were submitted to the minnesota veterinary diagnostic laboratory and included in our study. the majority of the animals were underweight ...201525390764
climate and habitat influence prevalence of meningeal worm infection in north dakota, usa.the meningeal worm (parelaphostrongylus tenuis) is a parasite of white-tailed deer (odocoileus virginianus) and is also a significant pathogen of moose (alces alces) and other ungulates. changes in climate or habitat may facilitate range expansion or increase the prevalence of meningeal worm infection in white-tailed deer, resulting in increased exposure to susceptible ungulates. we examined 3,730 white-tailed deer during 2002-05 to determine the prevalence and range of meningeal worm infection ...201525973622
