Effect of simultaneous injection of classical swine fever virus vaccine and Mycoplasma hyopneumoniae vaccine on immune response of swine
Objectives of this study were (1) to compare sero-conversion in pigs following simultaneous and separate vaccination against Classical Swine Fever (CSF) and Mycoplasma hyopneumoniae and (2) to determine safety of CSF and M. hyopneumoniae vaccines when given simultaneously. Twenty-four weaned pigs we...

| Summary: | Objectives of this study were (1) to compare sero-conversion in pigs following simultaneous and separate vaccination against Classical Swine Fever (CSF) and Mycoplasma hyopneumoniae and (2) to determine safety of CSF and M. hyopneumoniae vaccines when given simultaneously. Twenty-four weaned pigs were divided into 3 groups of 8 heads. Groups were designated as non-simultaneous vaccinated group, simultaneous vaccinated group and negative control, respectively. Vaccines used in study were M.hyopneumoniae vaccine (SPRINTVAC®MH) and CSF vaccine (PESTIFFA®). IDEXX ELISA test kit (HerdChek M hyo) and LSIVET SUIS HC/PPC Blocking ELISA test kit were used to detect antibody titre on weekly basis. Sero-conversion rate of CSF antibody titre and M.hyo antibody titre were calculated. Result showed both simultaneous vaccination and non-simultaneous vaccination for CSF antibody titre reached 100% sero-conversion rate at 5 weeks post vaccination. Therefore, simultaneous vaccination was able to accomplish similar results as in non-simultaneous vaccination. Sero-conversion rate for CSF antibody titre in non-simultaneous group was slower before it reached 5 weeks post vaccination. 12.5% of animal from negative control group sero-converted at 5 weeks post vaccination due to false-positive result or field infections. M. hyopneumoniae antibody titre sero-conversion rate in both simultaneous vaccination and non-simultaneous vaccination reached 100% sero-conversion rate after 6 weeks post vaccination. Control group showed negative result for M. hyopneumoniae antibody titre throughout whole experiment. Vaccines used in trial did not cause any adverse effect after post vaccination when given simultaneously. |
