Abstrakt: The purpose of this article is to study the effect of the probiotic on experimental infections of carp's fingerlings with Lactococcus garvieae. Lactic acid bacteria (LAB) (Lactobacillus fermentum 24с, Pediococcus pentosaceus 10/9к, Lactobacillus paracasei 9c) for the probiotic were previously isolated from the intestines of mature carps from Maybalyk commercial fisheries, which provided fingerlings for this experiment too as well. The feed-contained probiotic was given to fish in the experimental group for 14 days before challenge with pathogen L. garvieae. Throughout ten days after the infection, death of the fish was regularly recorded in the group, where the probiotic was not given with the feeding. Ten days after, all fish in this group died. In the probiotic group, the mortality on the tenth day after the challenge with pathogen was 10%. It was concluded the effect of the probiotic is not due to antibacterial action to the pathogen. The effectiveness of the probiotic can be associated with the displacement of the pathogen, due to the competitive adhesion and/or more likely, with the activation of the immune response from the fish organism due to the addition of the probiotic to the feed.
