Abstract | The epidemiologically justified mass immunization of cattle with live antibrucellosis vaccines in unfavorable areas during the widespread occurrence of brucellosis is currently unreasonable for prosperous regions, from both the environmental and economic point of view. In this regard, the transition to alternative schemes of specific prevention of brucellosis using environmentally safe products is very reasonable. The research was aimed at studying the antiepizootic efficacy of the concomitant use of the antibrucellosis environmentally safe chemical vaccine (ACV) and the vaccine from the Brucella abortus 82 strain at arresting the focus of brucellosis infection. It has been found that the immunization with ACV not only allowed to neutralize the abortogenic properties of the vaccine from the strain 82 but also not to provoke the latent forms of brucellosis reducing thereby the recovery periods of cattle herds from this infectious disease.
