Primena autogenih vakcina u farmskom uzgoju životinja

Abstract

The base of herd health management are preventive measures where vaccination may play an important role. However, for immunoprophylaxis in exact herd limitation could be commercial vaccine availability with desirable antigen and also the possibility of antigens diversity of same pathogens what can diminish of the effectiveness of the commercial vaccine in a certain population. In that case, the solution is the use of autogenous vaccines, vaccines prepared from microorganisms isolated in certain populations and intended for use in the same populations. The key point for use of the autogenous vaccine is the correct determination of microbiological etiology for the disease of interest, which, considering the multifactorial nature of the disease can be challenging. For autogenous vaccine, the most important pathogen in disease etiology should be determined. Possibility of the combination of different antigens important for one farm in one vaccine is a special benefit of autogenous vaccine, considering farm technology, animals flow in farm and category of animals which need to be immunized (e.g. good colostrum quality achieving). Experience showed that autogenous vaccine using appropriate antigen improves health status, lowers losses, and also reduces antibiotic use which is an additional benefit considering the decrease in the development of antimicrobial-resistant strains.
