Observations on parasite–host relationships of Echinococcus multilocularis Leuckart, 1863, in North Dakota
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 infectio...
