Дія секретів шкірних залоз Abramis brama на бактерії Erysipelothrix rhusiopathiae

Abstract

З’ясовано, що продукти секреції шкірних залоз ляща звичайного (Abramis brama) in vitro здійснюють стимуляційний вплив на популяції патогенних бактерій Erysipelothrix rhusiopathiae. Між піддослідними видами можливе формування топічних, трофічних та форичних типів біоценотичних зв’язків. The investigation of the influence of cutaneous secretions of Abramis brama on the populations of pathogenic Erysipelothrix rhusiopathiae bacteria. Favorable conditions for the reproduction and increase in the density of populations of pathogenic E. Rhusiopathiae bacteria are formed in an aqueous environment that contains the secretions of skin glands of A. brama. In the conditions of freshwater ecosystems, direct topical biocenotical relations between pathogenic E. rhusiopathiae bacteria and the A. brama may be formed. The quantitative data that demonstrate the stimulating effect of cutaneous secretions of A. brama on the populations of pathogenic E. rhusiopathiae bacteria have been obtained for the first time. The stimulating effect of cutaneous secretions of A. brama populations on E. rhusiopathiae indicates one of the possible directions of long-term persistence of these infectious agents in hydrobiocenoses. The revealed environmental aspects of the existence of pathogenic E. rhusiopathiae bacteria in freshwater ecosystems should be taken into consideration while planning and implementing measures aimed at preventing the erysipelas disease.
