Tubercle Bacilli in the Faeces of apparently healthy Cows

Abstract

(1) Samples of faeces of 391 cows in apparently good health have been examined and it has been demonstrated that 6 (1.53 per cent.) of the cows were excreting tubercle bacilli.(2) When the faeces of almost all the cows on founrteen farms were examined it was found that five cows on four farms were excreting tubercle bacilli.Our thanks are due to the Medical Research Council for the grant which enabled us to carry out this investigation.
