Host Relationships

Red foxes, Vulpes vulpes (Linnaeus), and small mammals were collected and examined during 1965–69, to investigate parasite–host relationships of Echinococcus multilocularis Leuckart, 1863, in North Dakota. Comparative studies of this cestode were carried on concurrently through experimental infection of carnivores and rodents. In winter, red foxes in North Dakota exhibited high rates of infection of comparatively low intensity. Deer mice, Peromyscus maniculatus (Wagner), and voles, Microtus pennsylvanicus (Ord), were important intermediate hosts, but the larvae in deer mice produced fewer protoscolices. The strains of E. multilocularis from North Dakota and from St. Lawrence Island, Alaska, differ biologically, as indicated by findings in experimentally infected rodents, but they could not be distinguished morphologically at the infraspecific level. Helminths recorded from red foxes in North Dakota are listed, and some ecological data are presented and discussed.

Paruterina candelabraria was found in 4 out of 40 rodents collected in gravel pits near St. Lupicin, Mulvihill, Wasagaming, and Lockport, Manitoba. The hosts were Microtus pennsylvanicus and Peromyscus maniculatus. Cladotaenia globifera was found in 1 out of 15 M. pennsylvanicus collected near Bissett, Manitoba.

Three new Psorergates species parasitic in epithelium of the external ear of Sorex cinereus Kerr, Microtus pennsylvanicus (Ord), and Peromyscus maniculatus (Wagner) are described and figured in detail. Distinctive features of species of the "insectivora" and "dissimilis" groups of the genus Psorergates Tyrell are tabulated.

Larval Echinococcus multilocularis was found in one of 25 Peromyscus maniculatus collected in a dolomite quarry near Gunton, about 30 miles north of Winnipeg. This finding shows that E. multilocularis is present in Manitoban rodents at least in an area of 60 sq. mi.

Ectoparasites and other associates were examined from seven species of insectivores and nine species of rodents from Mount Carleton Provincial Park, New Brunswick. The most abundant forms found were (at least 2.0 per host individual) the following: Orycteroxenus soricis and Amorphacarus hengererorum on Sorex cinereus and on Sorex (Microsorex) hoyi; A. hengererorum and O. soricis on Sorex fumeus; O. soricis, Miyatrombicula esoensis, and Ixodes angustus on Sorex gaspensis; O. soricis, I. angustus, Pygmephorus horridus, and Protomyobia americana on Blarina brevicauda; M. esoensis, Protomyobia claparedei, and Glycyphagus hypudaei on Sorex palustris; Orycteroxenus canadensis, O. soricis, P. horridus, G. hypudaei, Ctenophthalmus pseudagyrtes, and Haemogamasus ambulans on Condylura cristata. More abundant ectoparasites of the rodents were as follows: G. hypudaei, Listrophorus mexicanus, M. esoensis, Neotrombicula harperi, and Radfordia lemnina on Clethrionomys gapperi; G. hypudaei, L. mexicanus, M. esoensis, N. harperi, and Laelaps kochi on Microtus chrotorrhinus; L. mexicanus, G. hypudaei, Radfordia hylandi, Laelaps alaskensis, M. esoensis, Polyplax alaskensis, L. kochi, N. harperi, and Myocoptes j. japonensis on Microtus pennsylvanicus; Listrophorus synaptomys, Hoplopleura acanthopus, L. alaskensis, G. hypudaei, M. esoensis, I. angustus, R. hylandi, and N. harperi on Synaptomys cooperi; all of these except the last one on Synaptomys borealis; M. esoensis on Peromyscus maniculatus; Dermacarus newyorkensis on Zapus hudsonius; D. newyorkensis, N. harperi, Radfordia ewingi, and G. hypudaei on Napaeozapus insignis; Dermacarus hylandi, N. harperi, Megabothris acerbus, and M. esoensis on Tamias striatus.

Gravel Pit

Cysts of Echinococcus multilocularis Leuck. 1863 were found in 15 of 99 deer mice, Peromyscus maniculatus (Wagner), from a dolomite quarry and a gravel pit 12 and 20 miles north northeast of Winnipeg respectively, in the Stony Mountain – Argyle area. This is the first report on the occurrence of E. multilocularis in Manitoba rodents. It extends northeast the known area of distribution of this cestode in the North American prairies.
