Aberystwyth scientists in 'breakthrough' for worldwide fight against bovine TB

A traditional skin test for Bovine TB (bTB) shows a positive result for cows that have the disease as well as those that have been vaccinated against it.

That means vaccination is banned in the EU and the USA.

Now scientists at Aberystwyth working with others in Africa and Europe, have developed a test that can tell the difference. The next stage is to try it out in field trials.
