A skin test, called PPD (purified protein driver), is performed to check animals and especially cows suspected of TB.  It is a protein derived from tubercle bacils, which is produced by the reaction of animals with their skin when infected with TV.

 A new study published in the journal Scientific Reports states that for the first time a vaccine has been developed that can be given after a PPD skin test without affecting the investigation of TB disease in animals.  It is essential for the prevention of lung TB disease in animals.

 During this research, scientists at the University of Surrey conducted the test by removing a protein responsible for the immune response from the vaccine for PPD testing and developing a new skin protein using immunogenic proteins.  The benefit of this research will be that cows who have TB lung disease will be limited to them.  Cows to which this vaccine has been given will not be infected with infected cows.
