TB infection from cow to cow more likely than transmission by badger

Study is a first to show direct evidence of the disease passing between the two species

Tuberculosis in cattle can be spread by badgers but cow-to-cow transmission is more significant than badger-to-cow, according to the first study to provide direct evidence of the disease passing between the two species.

Scientists undertook whole genome sequencing of different strains of bovine TB to detect how it moved between cows and badgers in Woodchester Park, Gloucestershire.
