Demi-Lee Brennan was aged nine and seriously ill with liver failure when she received the transplant, doctors at a top Sydney children’s hospital told AFP.

Nine months later they discovered she had changed blood types and that her immune system had switched over to that of the donor after stem cells from the new liver migrated to her bone marrow.

She is now a healthy 15-year-old, Michael Stormon, a hepatologist treating her, told AFP. He said he had given several presentations on the case around the world and had heard of none like it.

Could it be another soul living inside her blood? LOL!

Recently there was a breakthrough in converting blood A, B, AB to O.

In a report released Sunday, researchers describe the use of newly discovered enzymes to convert blood types A, B, and AB into O, the universal donor type.

—— Reuters - Science & Health - Blood types A, B converted to O

What’s so great about this O blood? Don’t all the blood look alike?

Unfortunately even though all blood looks red, but they’re quite different. There are four blood types, which are A, B, AB and O. Blood type O is a universal donor blood type, which means it can be transfused to any other cell type. However, blood type O can only accept O only.

To see how different blood type works and what is the restriction of blood transfusion, you can read Blood type from Wikipedia. Wikipedia is always my favourite reference source.
