Helminths of Big Game Mammals in South Dakota

Gastrointestinal Strongyles in Wild Ruminants

“…Haemonchus contortus was the most commonly occurring nematode reported by Boddicker and Hugghins (1969) in A. americana examined in South Dakota (68% of 60 animals). With respect to other recorded hosts, prevalence and intensity have been relatively minimal except in Odocoileus spp., and in deer appear to vary geographically.…”

“…Boddicker and Hugghins (1969) reported hemorrhagic lesions when H. contortus, along with other trichostrongyles, were present in large numbers in pronghorn. In deer, and presumably other wild ruminants, haemonchosis is associated with severe blood loss (Foreyt and Trainer 1970).…”

“…"Specimens identitied as Nematodirella longissimespiculata by Boddicker and Hugghins (1969), were redetermined as N. antilocaprae by Lichtenfels and Pilitt (I 983b).…”

Opening a can of lungworms: Molecular characterization of Dictyocaulus (Nematoda: Dictyocaulidae) infecting North American bison (Bison bison)

“…Previous studies have suggested that bison grazed on range more likely to have been previously occupied by cattle have different parasite communities than bison grazing ranges without shared cattle history ( Avramenko et al, 2018 ). The current paradigm is that North American bison share the lungworm D. viviparus with cattle, likely due to range overlap, but this has not been confirmed using molecular methods ( Dikmans, 1936 ; Frick 1951 ; Locker, 1953 ; Boddicker and Hugghins, 1969 ; Wade et al, 1979 ). However, Dictyocaulus hadweni Chapin (1925) was historically described as a species in North American bison from western Canada ( Chapin, 1925 ; Roudabush 1936 ).…”

Synlophe in Ostertagia cf. kasakhstanica (Nematoda: Ostertagiinae), the Minor Morphotype of O. bisonis from Western North America

“…Observations reported here are based on a single specimen referable to O. cf. kasakhstanica (previously identified as T. trifurcata by Boddicker and Hugghins [1969]; U.S. National Parasite Collection 59388) from South Dakota, in Bison bison, the type host of O. bisonis. Lichtenfels and Pillit (1991) predicted that the cervical synlophe in O. kasakhstanica should be similar to that described for O. bisonis.…”
