The prevalence of M. bovis in badgers based on post-mortems and a subsequent analysis of the post-mortem protocol following the Randomised Badger Culling Trail (RBCT) showed prevalence of around 33%.
In the long-running study of badgers at Woodchester park TB prevalence in badgers has increased to over 30%.[1]
In a separate study in Gloucestershire between 35% and 53% of badgers tested positive to a TB test. [2]
