Treatment of chronic relapsing urinary tract infection with antibiotics selected by AtbFinder

We report the case of a 46-year-old patient who, after renal cancer surgery, developed a recurrent urinary tract infection that lasted for more than 2 years. Despite repeated antibiotic courses, including broad-spectrum drugs chosen using conventional antibiotic susceptibility testing, multiple reinfections followed. The patient was successfully treated once antibiotics were selected with AtbFinder. Unlike routine antimicrobial susceptibility methods, which select antibiotics effective only against a "lead bacterial pathogen," AtbFinder identifies antibiotics that target the mixture of bacteria at the infection site. This case demonstrates the ability of AtbFinder to successfully select antibiotics for the treatment of relapsing urinary tract infections.

[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 obtained results demonstrate that test-system permits choosing antibiotic during 6-20 hours without separation of pure culture.

[Distribution of bacterial spores in supermarkets]

This work presents results of the study on the environment prevalence of spores of aerobic bacteria, which are of potential danger to human health. The investigation of swabs from handles of supermarket trolleys revealed on their surface the presence of a large number of spores of unrelated pathogenic bacteria carrying as antibiotic resistance genes and the origin of genes protected by bacterial spores from harmful environmental conditions as well. The high resistance of bacterial spores to antiseptics and disinfectants can be considered as the reason for the their accumulation in the environment.

[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". The obtained data demonstrates that test-system permits to choose antibiotic during 6-20 hours without isolation of pure strain.

[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.
