the development of clinical signs and the population significance of neurologic disease in a captive wapiti herd.clinical signs attributable to meningeal worm (parelaphostrongylus tenuis) were recorded in three male and three female wapiti (cervus elaphus canadensis) ranging in age from 5 - 29 months. the study was conducted from september, 1976 to may, 1977 in a 2104-ha preserve. some differences were noted in occurrence, time schedule and sequence of signs but the basic pattern was similar. the mean time between initial sign observed and death was 100 days. the effect of neurologic disease on population ...1978650796
gastropod availability and habitat utilization by wapiti and white-tailed deer sympatric on range enzootic for meningeal worm.gastropod occurrence and the utilization of habitat by sympatric populations of wapiti (cervus elephus) and white-tailed deer (odocoileus virginianus) on range enzootic for meningeal worm (parelaphostrongylus tenuis) were studied on cookson hills wildlife management area (wma) in eastern oklahoma. visual observations and fecal pellet group transect data indicated that wapiti spent the majority of their time in open fields and meadows where we recovered the least numbers of gastropods. although d ...19912023333
identification of dorsal-spined larvae from free-ranging wapiti (cervus elaphus) in southwestern manitoba, canada.dorsal-spined first-stage larvae recovered from feces of free-ranging wapiti (cervus elaphus) were passaged through snails (triodopsis multilineata) and two hand-raised white-tailed deer fawns (odocoileus virginianus). a total of 74 adult parelaphostrongylus tenuis were recovered from the fawns; no other protostrongylid nematodes were recovered. the study indicates that wapiti may be infected with natural infections of meningeal worm and pass larvae suitable for transmission to gastropod interme ...19892716114
prevalence and effects of parelaphostrongylus tenuis in a captive wapiti population.prevalence of neurologic disease attributed to parelaphostrongylus tenuis was investigated in a population of wapii (cervus elaphus canadensis) enclosed in a 2080 ha. preserve. brains of 44 animals harvested in 1973, 1974 and 1975 were examined grossly and microscopically. prevalence of infection increased each year from 26.6% of the sample in 1973 to 64.3% in 1975. these data suggest that wapiti living close to white-tailed deer (odocoileus virginianus) may have a high prevalence of infection, ...1977864848
parelaphostrongylus andersoni (nematoda: protostrongylidae) in white-tailed deer from michigan.dorsal-spined larvae in fecal samples from free-ranging white-tailed deer (odocoileus virginianus) in michigan and pennsylvania were used as a source of larvae to infect a hand-raised white-tailed deer fawn. the fawn receive 200 third-stage larvae and passed dorsal-spined larvae in feces 66 days later. muscleworm (parelaphostrongylus andersoni), and meningeal worm (parelaphostrongylus tenuis) were recovered at necropsy. two white-tailed deer and seven wapiti (cervus elaphus) exposed to larvae of ...19902250330
a summary of the prevalence of parelaphostrongylus tenuis in a captive wapiti population.a total of 87 brains from harvested and collected wapiti and red deer (cervus spp.) were examined grossly and microscopically between 1973 and 1977 in a 2104 ha. preserve. prevalence of infection significantly increased from 26.6% of the sample in 1973 to 64.3% in 1975 (p less than .05). a decline to 47.7% in 1977 (p greater than .05) was not significant. however, the number of clinical cases was significantly higher in 1976-1977 (p less than .02) than previously reported in 1973-1975.1979459045
meningeal worm (parelaphostrongylus tenuis) as a cause of mortality in the restored elk (cervus canadensis) population in missouri.meningeal worm (parelaphostrongylus tenuis) is an important cause of mortality of elk (cervus canadensis) in populations in the eastern us and has been implicated in the failure of several restoration attempts. from 2011 to 2013, the missouri department of conservation translocated 108 adult and yearling elk from kentucky (us) to southern missouri (us) to establish a free-ranging population. from release in spring 2011 through august 2015, we monitored 167 elk (adult, yearling, and calf) to dete ...201728820300
