Absorption and excretion of vitamin B12 in subjects infected with Diphyllobothrium latum and in non-infected subjects following oral administration of radioactive B12



Absorption and excretion of vitamin B12 in subjects infected with Diphyllobothrium latum and in non-infected subjects following oral administration of radioactive B12



Acta Haematologica 19(2): 90-98



In anemic individuals infested with P. latum, the uptake of radioactive vitamin B12 by the worm was greater than in non-anemic carriers. Normal subjects absorbed about 55% more B12 than non-anemic tapeworm carriers, and the radioactivity of the feces was about 3 times higher in the first group. The radioactivity of expelled worms from carriers without anemia was about 180% higher than that of the feces. It is concluded that the tapeworm affects the host's capacity to absorb ingested vitamin B12.
