What you need to know to help stop the spread of Mycoplasma bovis.

  1. On this page:
  2. Look out for signs and report the disease.
  3. Practice good on-farm biosecurity.
  4. Managing seasonal cattle movements during Mycoplasma bovis eradication.
  5. Keep NAIT and animal movement records up to date.
  6. Protect stock when grazing off the home farm.

Is there a vaccine for Mycoplasma Bovis?
