#Norfolk : 14th Century DNA Extracted From Teeth BUT No Result From A Four Month Old Corpse ?

Skull DNA fragments were extracted from teeth

The researchers extracted DNA fragments of the ancient bacterium from the teeth of medieval corpses found in London.
They say the pathogen is the ancestor of all modern plagues.
The research, published in the journal Nature, suggests the 14th Century outbreak was also the first plague pandemic in history.

Speaking at a press conference at Norfolk Police’s headquarters in Wymondham, Detective Chief Inspector Jes Fry said the decomposed state of the body had complicated efforts to compile a DNA profile.

Samples were taken from the tooth, femur and muscle of the calf to test for a DNA profile. The first two sets of tests have not yet revealed a usable DNA Profile.

Once a DNA profile has been obtained, it will be checked against the national DNA database.

If no match is found, forensic experts will take samples from tooth and hairbrushes and other personal items belonging to known missing people.

In the absence of such evidence, the force will take samples from family members.

He added that personal artefacts, including jewellery, had been recovered from the area around where the body was found.
