Tuberculosis in cattle

Tuberculosis in cattle

Tuberculosis can be spread among cattle when they inhale the Mycobacterium bovis bacilli discharged from an infected cow, or when they drink water or eat pasture contaminated by infected dung. The bacilli may also enter the body through wounds or scratches. The disease develops over a number of years and results in weakness, coughing and weight loss. Advanced stages of the disease, seen in this cow, are now uncommon in New Zealand.
