[Metagenomic analysis of samples in cystitis].

Detecting bacteria in pathological material and testing their sensitivity to antibiotics is essential in determining a treatment strategy and the choice of antimicrobial therapy. The results of the study showed that metagenomic analysis detects more bacteria in the pathological material than standard laboratory methods. We found a variety of bacteria, described as causative agents of urinary tract infections, evading the standard culture conditions used in routine diagnostic laboratories.

[The choice of antibiotic in microbiological study of pyoinflammatory processes.].

The efficiency of application of test-system "Antibiotic Choice" was examined concerning evaluation of sensitivity to medications of maximal possible number of bacteria from pathological samples at burn trauma without isolation of pure culture. The results of metagenome analysis demonstrated that test-system permits supporting factually all bacteria discovered in wound discharge, including ones related to not cultivated yet. The comparison was carried out concerning results of standard identification of sensitivity of bacteria to antibiotics and efficient medication according the results of application of test-system "Antibiotic Choice".

[The choice of antibiotic in microbiological analysis of phlegm.].

The efficiency of application of the test-system "Vy`borAntibiotika" (AntibioticChoice) in incubation of a maximal possible number of bacteria from pathologic material in case of pneumonia was studied. The results of meta-genome analysis permitted to establish that test-system support incubation of practically all bacteria detected in phlegm, including those attributed to so far non-incubated ones. The comparison of the results was carried out concerning a standard detection of sensitivity of bacteria to antibiotics and choice of efficient medicinal according the results of application of test-system "Vy`borAntibiotika".

[CHOOSING ANTIBIOTIC IN MICROBIOLOGICAL ANALYSIS OF INFECTIONS OF URINARY EXCRETION SYSTEM].

The effectiveness of application of test-system "Choice of antibiotic" was evaluated as a tool for incubation of maximal amount of bacteria from pathological material under acute cystitis. The results of meta-genome analysis established that test-system permits supporting growth of practically all bacteria detected in urine, including ones relating to "uncultivated for the present". The comparison of results of standard detection of sensitivity of bacteria to antibiotics and identification of effective pharmaceutical according the results of application of test-system "Choice of antibiotic" as well was implemented It is demonstrated that test- system permits choosing antibiotic during 6-20 hours wiihout isolation of pure strain.

[Antibiotic Resistance of MRSA in the Russian Federation].

The results of the multicentre trial on estimation of MRSA antibiotic susceptibility to 17 antibiotics are presented. 474 nonrepeting isolates of MRSA (mecA+), collected in 2011-2014 in 10 cities of the Russian Federation were used in the trial. The antibiotic susceptibility was determined by the method of serial microdilutions in broth with estimation of the MICs in accordance with the international standards CLSI 2014 and EUCAST 2014.

[Estimation of MRSA susceptibility to oxacillin, cefoxitine, vancomycin and daptomycin].

Prevalence and therapy of infections due to MRSA remain one of the most serious problems in the world. Therefore, correct laboratory identification of the MRSA phenotype based on the use of the marker antibiotic cefoxitine, as a more susceptibile one vs. oxacillin, is of great importance.
