Researchers Find Way to Convert Type A Blood to Type O

June 19, 2019

(Medscape) – Researchers have found a way to use a pair of enzymes from a human gut bacterium to convert type A to the universal donor type O blood, according to a report published June 10 in Nature Microbiology. The researchers say the high activity and specificity of these enzymes “make these very promising candidates for cost-efficient implementation into the already existing automated routines of blood collection, processing and storage, with major implications for the flexibility of our blood supply and possible applications in organ transplantation.”
