The trematode Metorchis conjunctus (Cobbold, 1860) was found in seven of 211 wolves from Saskatchewan which were examined between 1976 and 1983. The parasite caused cholangiohepatitis with periductular fibrosis in the liver of all the wolves, and chronic inflammation and fibrosis of the pancreas in two animals. The wolves with pancreatic involvement were emaciated. Five of the seven infected wolves were from one local area, and three of these were from a pack known to consume fish. 

The North American Liver Fluke, Metorchis conjunctus

TLDR
The present outbreak and the prevalence of the fluke M. conjunctus place this parasite among the more common fish-borne helminths that infect humans in North America.

Opisthorchiidosis--a review.

TLDR
Although opisthorchiid flukes live in the bile ducts of the liver and in the gall bladder, they can affect surrounding liver tissue and even other organs and the main medical significance is their role in the formation of malignant tumors.

Parasitic Zoonoses: One Health Surveillance in Northern Saskatchewan

TLDR
A joint human-animal health investigation in a Dene community in northern Saskatchewan, where residents harvest wildlife, live in close contact with free roaming dogs, and lack access to permanent veterinary services, demonstrates the potential utility of canine de-worming as a public health intervention.

First records of Trichodectes canis (Insecta: Phthiraptera: Trichodectidae) from Darwin’s fox, Pseudalopex fulvipes (Mammalia: Carnivora: Canidae)

TLDR
The presence of the dog biting louse, Trichodectes canis, is reported for the first time in the critically endangered Pseudalopex fulvipes in Chiloé Island, south Chile.

Infectious Forms of Parasites in Food: Man Embedded in Ecosystems

TLDR
Although common representations of human daily life show a humanity that has in some way “escaped” from ecosystems, men take on their role of top level consumers, and are therefore exposed to the associated highly diversified parasitological risk.

Non-native species in Canada’s boreal zone: diversity, impacts, and risk1

More than 1180 non-native species, mostly of Palaearctic origin, have been recorded from the boreal zone of Canada, with the highest diversity on the island of Newfoundland and in the southern boreal

A ONE HEALTH APPROACH TO ECHINOCOCCUS CANADENSIS AND OTHER PARASITIC ZOONOSES IN REMOTE, RURAL AND INDIGENOUS COMMUNITIES

TLDR
This paper focuses on surveillance for Echinococcus canadensis genotypes in Canadian ungulates and the impact of climate and landscape change on transmission, prevalence, and public health impact.

TLDR
Marked hyperplasia of the mucosa of the intrahepatic bile ducts and gall bladder was found and the inflammatory reaction consisted principally of lymphocytes and plasma cells with a few eosino-phils.

The Morphology, Taxonomy, and Life History of Metorchis conjunctus (Cobbold, 1860).

A trematode, widely distributed in Canada, and occurring in man and other fish-eating mammals, is described and its taxonomy discussed. Its life cycle has been worked out and it is shown to involve a

Pancreatic function in domestic cats with pancreatic fluke infection.

TLDR
In some cats, the pancreas was severely affected, with almost complete atrophy and fibrous replacement of the gland, and both bicarbonate and protein secretions were impaired, although clinically evident pancreatic insufficiency was not seen.

TLDR
It is shown that the invasion by the trematode triggers off a latent infection and causes an exacerbation of symptoms which otherwise would have remained subclinical.

The helminths of wolves and coyotes from the forested regions of Alberta

TLDR
Helminths common in wolves were Taenia hydatigena, Echinococcus granulosus, T. taeniaeformis, and T. omissa, which appear to be new records for wolves and M. conjunctus, TaenIA twitchelli, Diphyllobothrium sp.

TLDR
A total of 959 faecal samples were obtained from dogs in 12 native communities in Northern Saskatchewan, Central and Northern Alberta and the Northwest Territories, and infections with parasites of no known zoonotic importance such as Trichuris, Alaria and Isospora species were recorded.
