Thirteen diary cows were diagnosed as bovine tuberculosis (BTB) based on pathological findings and PCR method from 74 diary cows slaughtered in Incheon city. BTB was outbreaked 9 times in the farm from March 2010 to June 2013. The BTB confirmed cows were all negatives by intradermal test with PPD at 3 times.
