Tuberculosis in cattle and badgers passes between members of the same species at least twice as often than between cow and badger.

Disease spread within badger populations and within cattle herds happens at least twice as frequently as transmission from one species to the other, according to a study at a site where infections occur frequently.

Researchers analysing genetic data from the bacteria that causes the disease also found that cattle are approximately ten times more likely to catch tuberculosis (TB) from badgers than badgers are to catch it from cattle.

Scientists say the findings of the research – which was conducted in Gloucestershire over a 15-year period – could improve control strategies, reduce disease transmission and cut associated costs.
