Trichinella sp. in polar bears from Svalbard, in relation to hide length and age

  title={Trichinella sp. in polar bears from Svalbard, in relation to hide length and age},
  author={Thor S. Larsen and Bj{\o}rn Kjos-Hanssen},
  journal={Polar Research},
Diaphragm and masseter muscles from 376 polar bears ((irsur maririmus), 252 ringed seals (Phocn hispida), 84 bearded seals (Erignarhus barbarus), and 77 arctic foxes (Alopex lagopus) from Svalbard were examined for Trichinelln. Infection rates in polar bears varied between 23 and 58%, and between 3 and 67% in arctic fox. None of the seals were infected. Trichrnella in polar bears is probably transferred through cannibalism and scavenging upon polar bear carcasses. Infection rate in arctic fox…

A serosurvey for Trichinella in Arctic foxes (Vulpes lagopus) in Svalbard

Examining arctic foxes from Svalbard in 1996–2004 for antibodies against Trichinella spp.

Trichinella and polar bears: a limited risk for humans

Polar bears seem to play a limited role in the transmission of trichinellosis to humans, as native residents living in the Arctic traditionally consume well-cooked bear meat, and travellers and foreign hunters have only limited access to this protected species due to the declining polar bear population.

Serosurvey of selected zoonotic agents in polar bears (Ursus maritimus)

Subadults and yearlings were 2˙62 times more likely to be seropositive for Brucella species than adults and their cubs, and the prevalence of antibodies to Trichinella species increased with age (P<0˙001).

Epidemiology of Trichinella in the Arctic and subarctic: A review

Status and biology of ringed seals ( Phoca hispida ) in Svalbard

The ringed seal is the most abundant mammal in the Svalbard area, and heavy predation pressure is probably the main factor explaining why pups of this species start diving at such a young age, why they have access to so many breathing holes and why they keep their white coat long after its thermoregulatory properties have vanished.

Trichinella nativa in Iceland: an example of Trichinella dispersion in a frigid zone

This is the second report of Trichinella infection in polar bears that reached the Icelandic coast and the epidemiological features that have allowed T. nativa to spread in Arctic regions are discussed.

Prevalence of Trichinella sp. in polar bears (Ursus maritimus) from northeastern Greenland

The occurrence of infections with Trichinella sp. in polar bears (Ursus maritimus) from northeastern Greenland has been studied by examination of muscle samples, mainly diaphragm, from 38 animals



Studies on the helminth fauna of Alaska. XXVII. The occurrence of larvae of Trichinella spiralis in Alaskan mammals.

An effort was made to obtain a series of each species of mammal occurring in Alaska, with exception of the ungulates, and the presence of Trichinella larvae was determined through the artificial digestion of tissue samples.

Carnivorous Walrus and Some Arctic Zoonoses

Reports of walrus feeding on seal or whale carrion, or killing them for food, and the possibility is aired that such animals like the polar bear, have a high vitamin A content in their liver, or may be a source of trichinosis transmissible to man.

Experimental transmission of Trichinella spiralis via marine amphipods

Groups of amphipods from the Bering Sea were fed the flesh of black bears, Ursus americanus, containing encysted larvae of Trichinella spiralis of Alaskan polar bear and brown bear origin, and in the expelled ingesta of 7000 amphipod that had fed for 1 hour were found 17 intact, excysted larva of T. spiralis.

Population ecology studies of the polar bear in northern Labrador

Résumé During spring 1976-79 we marked and recaptured polar bears in northern Labrador. Thirty-seven polar bears were captured and individually tagged. Most were found along the interface between the

Alaskan Polar Bear Denning

: Information on 35 overwinter maternity dens of Alaskan polar bears (Ursus maritimnus Phipps) and on 101 female polar bears with cubs, recently emerged from dens, was obtained by aerial and ground

Trichinosis in Arctic Animals

It was proved that the disease was trichinosis, and most of the cases were apparently due to the consumption of walrus meat, which had been sent to them from Holsteinsborg, which was one of the centres of the epidemic.

Trichinelh spiralis in walruses from the Thüle district, North Greenland, and possible routes of transmission

It is suggested that the walrus in the Thüle district contracts trichinosis from scavenging on carcasses of polar bears or/and sied dogs.

Studies on the helminth fauna of Alaska. XXV. The ecology and public health significance of Echinococcus sibiricensis Rausch & Schiller, 1954, on St. Lawrence Island.

It is concluded that E. sibiricensis is the etiologic agent of alveolar hydatid disease in man and Microtine rodents, particularly Microtus spp.

Satellite Radio-Tracking of Polar Bears between Svalbard and Greenland

An aerial survey program in 1977 and 1979 revealed that tracks of polar bears (Ursus maritinus) were abundant from Svalbard to Northeast Greenland south of 81? north latitude. In order to obtain

Problems of nomenclature for the growth of organisms of one species with and without associated organisms of other species

It is highly desirable an assessment of the nomenclature to be used in describing various relationships between organisms, both in nature and in the laboratory.
