Contagious agalactia (CA) is one of the main contagious diseases that affect small ruminants. The main causal agent is Mycoplasma agalactiae, a contagious bacterium that leads to chronic infections. Prophylaxis is considered to be the most viable, economical and sustainable method to combat this pathogen. There are currently several inactivated vaccines against M. agalactiae in Spain. The objective of this study was to compare the short-term and long-term serological response to different commercial vaccines against M.agalactiae available in Spain.

Vaccination with AGALAXIPRA® showed the best and fastest seroconversion in the first 21 days compared with other commercial aqueous vaccines. Furthermore, only AGALAXIPRA® and vaccine C were able to induce a better serological response than the control group during all 210 days of the study.
