Pepovich, R. (2019). Efficacy of single-dose Mycoplasma hyopneumoniae vaccine for the control of enzootic pneumonia in pigs. Bulgarian Journal of Agricultural Science, 25(5), 1039–1043
This paper evaluates the profilactic efficiency of the inactivated vaccine with single application for control of the enzootic pneumonia. The research was conducted at an industrial pig farm, on one hundred pigs, divided into two groups after the first weеk of their birth. One group was vaccinated once on 21st day with commercial inactivated M. hyopneumoniae vaccine (Ingelvac MycoFLEX®), and the other group was left non-vaccinated. It was demonstrated that the vaccine lowered the clinical signs and the damage of the lungs considerably and has led to improvement of the production results for the whole period of the research. Despite the economically justified result by the singular application of the vaccine against M. hyopneumoniae, this must be in line with the specific epidemiological situation in the farm, following a careful assessment of the infective pressure caused by M. hyopneumoniae, which determines the necessity of conducting more reaserch in the future.
