Mycoplasma bovis virulent strain and application thereof

The invention provides a mycoplasma bovis virulent strain and application thereof, and belongs to the technical field of microorganisms. The mycoplasma bovis virulent strain is classified and named asthe mycoplasma bovis virulent strain16M, and the preservation number of the mycoplasma bovis virulent strain in China Center for Type Culture Collection (CCTCC) is M2019235. The virulent strain can induce asthma, obvious lung consolidation and other mycoplasma bovis infected typical clinical symptoms and has very high invasiveness to the lung of a cattle, the live bacteria titer of the strain ishigh, the virulence is high, the pathogenicity is high, the time for the infected cow to excrete bacteria is long, onset of the disease is fast, and after toxic substances are counteracted, the re-separation rate of the toxic strain in the lung is high. The mycoplasma bovis virulent strain can be used for building a mycoplasma bovis invasion model with typical symptoms, the mycoplasma bovis invasion model conforms to the c
