Signs & symptoms
- Weight loss and wasting
- Breathing difficulty or rapid breathing
- Lethargy, lying down
- Sudden death with lung or abdominal lesions
What causes it?
Mycobacterium bovis (and M. microti in the UK), spread by inhalation or ingestion from infected cattle, wildlife (e.g., badgers in the UK) or other camelids.
Risk factors
- Regions with bovine TB in cattle or wildlife
- Buying animals without pre-movement testing
How vets diagnose it
Skin tests are unreliable in camelids. Validated blood antibody tests are used in some countries; confirmation by culture at necropsy. TB is a notifiable disease.
Treatment
Treatment is not permitted; suspected cases must be reported to the veterinary authority.
Do not wait to see if it improves. Camelids hide illness, and by the time signs are obvious the problem is often advanced. Call your veterinarian.
Prevention
- Buy from herds in TB testing schemes
- Use pre- and post-movement blood testing where available
- Limit wildlife access to feed and water
Can people catch it?
M. bovis can infect people. Wear protection and follow official guidance.
