Evaluation of the Feasibility of Using Commercial Wound Coatings as a Carrier Matrix for Bacteriophages.

Unlabelled: is to study the possibility of applying commercial wound coatings for treating infected wounds as a carrier matrix for bacteriophages.

Materials And Methods: Twelve varieties of commercial wound coverings based on biopolymers of natural and synthetic origin, a biological preparation Staphylophag produced by scientific-industrial association Microgen (Russia), registration certificate P N001973/01, and the 3196 test strain (GenBank JARQZO000000000) isolated from a patient with a burn wound have been used in our work. The ability of commercial biological wound coatings to absorb solutions was examined by immersing them in a physiological solution (pH 7.

Genome Features of Probiotic Bifidobacteria Determining Their Strain-Specific Properties.

Unlabelled: was to analyze the genome features of the probiotic strains 379, 1, and 791 and study their antiviral activity.

Materials And Methods: Whole genome sequencing of three strains of bifidobacteria was performed on the MiSeq platform (Illumina Inc., USA).

Colon Microbiocenosis and Its Correction in Patients Receiving Programmed Hemodialysis.

Unlabelled: was to study the species composition of colon microbiocenosis in patients with chronic kidney disease receiving programmed hemodialysis treatment and to evaluate the efficacy of its correction using a new immobilized synbiotic.

Materials And Methods: Samples of colon microbiota from 62 patients undergoing programmed hemodialysis were studied before and after a course of diet therapy that included probiotic components, in particular, the immobilized synbiotic LB-complex L. Isolation of microorganisms was carried out according to our original method; for bacteria identification, a MALDI-TOF Autoflex speed mass spectrometer (Bruker Daltonik, Germany) was used in the Biotyper program mode.

Genome Features and Activity against Influenza A and SARS-CoV-2 Viruses of Six Probiotic Strains.

Purpose: The aim of this work was to analyze the complete genome of probiotic bacteria 8 RA 3, 90 TC-4, 39, 791, 1, and 379 and to test their activity against influenza A and SARS-CoV-2 viruses.

Methods: To confirm the taxonomic affiliation of the bacterial strains, MALDI TOF mass spectrometry and biochemical test systems were used. Whole genome sequencing was performed on the Illumina Inc.

[Evaluation of anti-candida activity of metabolites of enterococcal clinical isolates.].

When studying the effect of the metabolic products of clinical isolates of enterococci on the viability of Candida albicans, it was found that metabolites of all tested strains of Enterococcus faecium, E. faecalis had a fungistatic effect. At the same time a reliable fungicidal effect is a strain-specific feature.
