“Their ability to completely convert A to O of the same rhesus type at very low enzyme concentrations in whole blood will simplify their incorporation into blood transfusion practice, broadening blood supply.”Įnter your email address to subscribe to this blog and receive notifications of new posts by email. Among the genes encoded in our library of 19,500 expressed fosmids bearing gut bacterial DNA, we identify an enzyme pair from the obligate anaerobe Flavonifractor plautii that work in concert to efficiently convert the A antigen to the H antigen of O type blood, via a galactosamine intermediate.” “Here we report the functional metagenomic screening of the human gut microbiome for enzymes that can remove the cognate A and B type sugar antigens. according to the study in the 2nd link’s abstract: so whatever Rh (D) factor the blood starts as, it stays that way – positive or negative when it’s converted to O. the bacteria apparently do not remove the Rh (D) positive factor. they’re seeking also to do the same w/ type B blood antigens.
hmm, some gut bacteria were found that seem to able convert/remove the A antigen and turn type A blood into essentially type O blood.
A NEGATIVE BLOOD TYPE TRAITS FREE
“Researchers were able to find bacteria in the human gut that produce two enzymes stripping type A blood’s antigens turning it in to antigen free type O negative blood cells.įurther studies need to be conducted to insure all blood antigens are removed from the type A blood, but if proved successful, the conversion type A blood would revolutionize blood transfusions.” “Researchers from the University of British Columbia in Canada have found a way to convert Type A blood in to a universally accepted form, potentially doubling the amount of universally accepted blood available. Very interesting…seems like it might finally take some pressure off the O negs like myself.
