Bacteria are passed out in the faeces and in milk. Transmission mainly occurs from infected cows to their calves when the calves drink milk from teats contaminated by faeces. Other young cattle (less than 12 months of age) can become infected by ingesting pasture and drinking water contaminated by infected faeces.
