Abstract: Different types of adjuvants are different on the alloantigen immune adjuvant effect. To screen the ideal adjuvant of the inactivated vaccine of Mycoplasma ovipneumoniae (MO), the inactivated vaccines using 4 different adjuvants were respectively immunized adult rabbits and the determination of serum antibody titers were detected using the indirect hemagglutination kit after immunization from 1 to 9 weeks. The results showed that the 4 different vaccines could quickly produce antibodies after immunization. Furthermore, the rabbits antibodies using Buonavoglial's and ISA-760 adjuvant vaccines peaked at 3 weeks after vaccination ((5.67±0.70) log2,6.00 log2), and maintained the peak until in 9 weeks (6.00 log2,(6.00±1.00) log2). In addition to vaccines with MO ISA-206 and white oil adjuvant, the rabbit antibodies peaked in 4 weeks after immunization ((4.33±0.57) log2,5.00 log2) and decreased a titer until 9 weeks. According to the statistical analysis, the results showed that the immune enhancement effect of ISA-760 and Buonavoglial's adjuvant for the MO was significantly better than that of ISA-206 and white oil adjuvant (P<0.05). Therefore, the above results indicated that ISA-760 and Buonavoglial's were an ideal candidate for MO inactivated vaccine adjuvant and provided a scientific basis for studing the efficient of the inactivated vaccine for MO.
