A group of researchers in Denmark have discovered two enzymes they say can convert any donated blood to group O, the only type that is safe for everyone. The Elizabethkingia meningosepticum gut bacterium, a cause of opportunistic infections, targets the A antigen and Bacteroides fragilis removes the B antigen. The researchers say the purified enzymes are very efficient and they plan to work with a company in Massachusetts to plan clinical trials.
