Abstract
Purpose. The research is to establish the reaction of E. rhusiopathiae pathogenic bacteria populations to the influence of northern pike skin secretions. Methods. Samples of fish skin mucus were taken with the help of filter paper, extracted, sterilized, and tested on the cultures of E. rhusiopathiae. Results. The content of E. rhusiopathiae bacteria in the test material was bigger than in the control samples; in the 1:10 dilution samples of northern pike skin secretions it was 3.26 times bigger; in 1:100 dilutions — 2.54 times bigger; in 1:1000 samples — 1.20 times bigger.Conclusions. The populations of E. rhusiopathiae pathogenic bacteria undergo a stimulating influence produced by northern pike due to the secretion of biologically active substances in the fish environment by its skin glands

Key words: Erysipelothrix rhusiopathiae, northern pike, skin secretions, stimulating influence.
