However, a research team plans to use enzymes secreted by bacteria in your gut to turn A and B type blood into O at much greater speeds than anything previously possible. Per the UK's National Health Service (NHS), blood group A features A-type antigens on the red blood cells, along with anti-B antibodies - the handcuffs that pin down and identify threats to the immune system - within the plasma.

Types A, B, and AB reportedly contain antigens on their surfaces that make them only able to be donated to people with those blood types.

Withers collaborated with his colleague at UBC to use metagenomics in his search for the enzyme, Eurekalert reports. Using type-O negative blood in transfusions doesn't lead to risky, possibly life-threatening, reactions in the patient.

With aid from the Centre for Blood Research at the University of British Columbia, the researchers are applying for a patent on their new enzyme research and are testing more blood samples before beginning clinical trials.

An enzyme-driven process was first discovered in 1982 and research has carried on ever since. In some targeted situations in which type O blood is scarce, the ability to transform one type to another could come in handy, Ziman told Live Science.

While the researchers planned to start by sampling DNA from mosquitoes and leeches - both organisms that degrade blood - they ultimately found likely candidates in the human gut flora.

There are four types of blood, and unlike types A, B and AB, Type O blood is the universal blood donor and can be given to anyone.

Salas leads Indianapolis LPGA by two
She hit another birdie to finish with a 23-under 265, beating Lizette Salas of the US who edged her by two shots a day earlier. The American still had a chance to close out the victory in regulation but missed a birdie attempt at the 72nd hole.

Mueller's Russian Federation probe is 'McCarthyism at its worst'
McGahn's attorney William Burck added in a statement: "President Trump, through counsel, declined to assert any privilege over Mr. With McGahn speaking to Mueller's team, Quinn stressed, others are likely to do the same. "Rigged Witch Hunt!" Trump later wrote.

Manitoba affected by BC wildfire smoke, special air quality alert in effect
The fire was discovered July 27 and has since grown to almost 85,000 hectares, or slightly larger than the City of Calgary. The haze is better in some areas, but Environment Canada is warning of reduced visibility and air quality.

After discovering that gut bacteria uses a group of enzymes removes sugars off mucins, which are "proteins that line the gut wall", the researchers tested to see if they were capable at eliminating the antigens in Type A and Type B blood.

"If you can remove those antigens, which are just simple sugars, then you can convert A or B to O blood", he said.

That's the tantalizing question raised by a new study presented this week at the American Chemical Society (ACS) meeting in Boston.

The new process being used by Withers and his team is 30-times faster than previous methods. Last month the Red Cross put forth an emergency call for blood donors. That's why Type O negative blood is always in high demand during emergencies, when there is often little time to test a patient's blood type to make sure it matches a donor.

Burn and accident victims as well as patients undergoing surgery are all dependent on the availability of blood and platelets, but with critically low blood supplies, they may not be able to receive treatment, Healthline noted.

"Scientists have pursued the idea of adjusting donated blood to a common type for a while, but they have yet to find efficient, selective enzymes that are also safe and economical", he added.

The American Red Cross states that there are very specific ways in which blood must be donated to ensure safety.
