| Outline of Final Research Achievements |
Mycoplasma bovis is known as a significant pathogen and cause of large economic losses in beef and dairy calves worldwide. Numerous factors appear to play an important role in the development of disease during infection with M. bovis, e.g., inhibition of immune cell proliferation and induction of lymphocyte apoptosis. However, the mechanisms involved in M. bovis infections have not been explored and remain incompletely understood. We investigated the major cytokine mRNA expression of bovine mammary epithelial cells and bovine PBMC stimulated with M. bovis, and established mixed culture system for the evaluation of phage function. We clarified significant changes of cytokine gene expression of PBMC stimulated with M. bovis, and established mixed culture system consisted with mammary epithelial cells and PBMC. These results are important to develop novel methods to treat mycoplasma mastitis in dairy cows.
