摘要: Minke whale (Balaenoptera acutorostrata) blubber is rich in organohalogen contaminants, mercury, and n-3 fatty acids. In the present study we show that a daily intake of 50-200 g minke causes an impairment nonspecific specific cellular immune system West Greenland sledge dog (Canis familiaris). Immune reactions were measured by mitogen (PHA, Con A) antigen (KLH) intradermal testing, as used exposure levels similar to those Inuits polar bears (Ursus maritimus), it reasonable infer suffer from decreased resistance diseases. It speculated food sources are depleted thinning sea ice due climate change more research should assess forecasted rise additive immunopathy effects bears. Additionally, our suggests acid composition may be importance when investigating combined immunotoxic contaminated resources future Inuit bear studies.
