Cobalamin and iron deficiency still presents a challenge in hereditary hemorrhagic telangiectasia [PDF]

Scientific Reports
Hereditary hemorrhagic telangiectasia (HHT) leads to fragile blood vessels, causing frequent bleeding and anemia. Treatment mainly addresses iron levels and substitution. Although cobalamin (vitamin B12) is routinely tested in chronic anemia, its role in

Interspecies transfer of biosynthetic cobalamin for complete dechlorination of trichloroethene by Dehalococcoides mccartyi

Water Science and Technology, 2022
Complete dechlorination of trichloroethene (TCE) by Dehalococcoides mccartyi is catalyzed by reductive dehalogenases (RDases), which possess cobalamin as the crucial cofactor. However, virtually all D. mccartyi isolated thus far are corrinoid auxotrophs.

The Intestinal Microbiome in Dogs with Chronic Enteropathies and Cobalamin Deficiency or Normocobalaminemia—A Comparative Study

Animals, 2023
Cobalamin deficiency is a common sequela of chronic enteropathies (CE) in dogs. Studies comparing the intestinal microbiome of CE dogs with cobalamin deficiency to those that are normocobalaminemic are lacking.
