| epidemiologic and serologic definition of primary and secondary trichinosis in the arctic. | a large outbreak of trichinosis acquired from walrus in salluit in 1987 provided the immunologic and epidemiologic data from which two distinct clinical syndromes were identified. the first syndrome is the classic myopathic form with edema, fever, myalgia, and rash. the second is a persistent diarrheal illness with little edema or myalgia. the clinical presentations are paralleled by distinct differences in type and development of antibody response. the clinical and serologic profiles of the two ... | 1992 | 1569342 |
| the occurrence and ecology of trichinella in marine mammals. | trichinella in marine mammals has a circumpolar arctic distribution and a narrow range of host species. it is commonly found in polar bears (ursus maritimus), and increasingly in walruses (odobenus rosmarus) where it presents a significant zoonotic hazard. this has resulted in the implementation of food safety programs in some arctic communities to test harvested walrus meat for trichinella larvae prior to consumption. trichinella has been reported infrequently in bearded seals (erignathus barba ... | 2000 | 11099845 |
| experimental trichinella infection in seals. | the susceptibility of seals to infection with trichinella nativa and the cold tolerant characteristics of muscle larvae in seal meat were evaluated. two grey seals, halichoerus grypus, were inoculated with 5000 (100 larvae/kg) t. nativa larvae and two grey seals with 50000 (1000 larvae/kg). one seal from each dose group and two control seals were killed at 5 and 10 weeks post-inoculation (p.i.). at 5 weeks p.i., infection was established in both low and high dose seals with mean larval densities ... | 2003 | 14572509 |
| a preliminary investigation on the infectivity of trichinella larvae in traditional preparations of walrus meat. | this study evaluated the infectivity of trichinella nativa in freshly frozen walrus meat and traditionally aged walrus meat (igunaq) associated with two human outbreaks of trichinellosis in the canadian arctic. trichinella larvae recovered from walrus meat stored at -20 degrees c for up to 20 months remained infective for guinea pigs inoculated with 135 or 716 larval doses. however, none of the 4-5 and 10-month-old igunaq preparations contained infective t. nativa larvae as measured by bioassays ... | 2004 | 15278445 |
| occurrence and genotypic analysis of trichinella species in alaska marine-associated mammals of the bering and chukchi seas. | the zoonotic parasite trichinella is the causative agent of trichinellosis outbreaks in the circumpolar arctic. subsistence communities are particularly prone to trichinellosis due to traditional meat preparation methods and regional presence of a freeze-tolerant trichinella species (trichinella nativa). this study is the first application of a validated artificial digestion method in determining incidence of trichinella sp. in alaskan mammals. infection incidence in pinniped species (erignathus ... | 2014 | 24373515 |
| from science to action and from action to science: the nunavik trichinellosis prevention program. | during the 1980s, walrus-meat consumption caused infections with the parasite trichinella nativa in nunavik inhabitants. in response to these events, stakeholders set up the community-based nunavik trichinellosis prevention program (ntpp). the objectives of the present communication are to review the ntpp, describe how science and action were interwoven in its development and identify its assets and limitations. study design. descriptive study. | 2012 | 22789519 |
