Mycoplasma synoviae occurs commonly as a infection of the upper respiratory tract, often causing respiratory diseases, airsacculitis abnormalities, arthritis and retarded growth in chickens and turkeys. It is an important pathogen cause significant economic losses in the poultry industry. In order to control M. synoviae infection, we try to develop M. synoviae bacterin. Based on previous achievement, we further using selected adjuvant formulated with different concentrations of M. synoviae field isolated to select protective vaccine dose range.
