[Characteristic of virulence potential of clinical isolates of enterococci].

Aim: Determination of virulence of enterococci strains isolated from clinical material from humans on pheno- and genotype levels.

Materials And Methods: 30 strains of enterococci isolated from wound exudate, urine, newborn skin lavage were used in the study. Strain identification was carried out by multiplex PCR.

[Genetic characteristic of virulent potential of enterococci of human intestinal microbiota].

Aim: Determine prevalence of genetic determinants of virulence among enterococci strains comprising human intestine microbiota.

Materials And Methods: 81 enterococci strains isolated from intestine of individuals during examination for dysbiosis were used in the study. Strain identification was performed by using multiplex PCR.

[Features of microbiocenosis of the large intestine in dysbiotic disorders].

Aim: To determine features of intestinal microbiocenosis in dysbiosis as well as biological characteristics of isolated microflora in residents of Orenburg city.

Materials And Methods: 70 children one year old and 60 adult 1 - 60 years old were examined for dysbiosis. Bacteriologic identification of the large intestine's content was performed using method of serial dilutions.

[Multilocus sequence-typing of Enterococcus faecium fecal isolates].

Aim: Genetic characteristics of Enterococcus faecium strains isolated from human intestine in Russia.

Materials And Methods: Seven strains of E. faecium with antimicrobial activity against Gram-positive bacteria and yeast fungi were isolated from persons aged 4 months - 44 years.

[Formation of biofilms by fecal strains of enterobacteria and yeast fungi from Candida genus].

Aim: To assess the ability of bacteria and Candida genus' yeast fungi from human fecal microflora to form biofilms.

Materials And Methods: Thirty-one strains of enterobacteria and 45 strains of yeast fungi from Candida genus isolated from feces of patients during test on intestinal dysbiosis were used. In order to study the ability of microorganisms to form biofilms, level of binding of crystal violet by the formers in sterile 96-well polystyrene plates was studied.
