Kochkina E.E., Pashkova T.M., Sycheva M.V., Kartashova O.L. CHARACTERISTICOF BACTERIA OF THE GENUS ENTEROCOCCUS BIOPROFILES ISOLATED FROM ANIMALSThe increasing clinical significance of enterococci highlights the issue of the safety of their use as anti-infective biologics probiotic and requires the search algorithm for the effective differentiation of clinically significant strains from representatives metallisticheskoy microbiota.
Studied the biological properties of bacteria of the genus Enterococcus isolated from the feces of clinically healthy productive animals and from animals with infectious and inflammatory diseases. Determined bioprofile characterizing pathogenic and non-pathogenic isolates. In addition to the genetic determinants of the virulence factors of the strains isolated in the pathology detected hemolytic, gelatinase activity and the factors of persistence (ALA, Acre), with higher characteristic values than fecal cultures. Strains isolated from the intestines of healthy animals was characterized by a high activity of proteases and not had the ability to form biofilm.
The obtained results can be used for differentiation of pathogenic variants Enterococcus spp. from symbiotic cultures included in the composition of the intestinal normality.Key words: Enterococcus spp., differentiation, factors of persistence, factors of virulence, polymerase chain reaction.
