In the presented review the general data concerning probiotics is considered, i.e. definitions of the term, classification principles, and the core benefits of usage if compared to antibiotics. Are noted The criteria of choice and the characteristics of the main sorts of bacteria used as basic probiotics. Special attention in terms of usage for producing bacteriemic medicines is paid to Bacillus spore-former bacteria, as normal micro-flora exogenous components that do not produce biofilms. Bacillus spore-former bacteria are also able to produce a wide spectrum of biologically active substances, including antibiotics, lysozyme, proteolytic enzymes, and able to influence the immunological reactivity of macro-organism, therefore stimulating the growth of secretory immunoglobulins`, macrophages`, natural killers` activity. The Subalinum biological features are considered. The basic for Subalinum is genetically modified strain of Bacillus subtillis 2335/105 with a plasmid, containing the gene for alpha-2 human interferon. The characteristics for genetically modified strains of E. coli is given, as being perspective for creating probiotics for effective treatment of diarrhea, caused by enterotoxigenic E.coli and Vibrio cholera. They are proposed for creating recombinant strains of bifidobacteria for atherosclerosis and cardiovascular diseases` treatment and prevention. They are also prospective for making Lactococcus lactis recombinative strain for ulcerative colitis and Crohn's diseases` treatment. The potential dangers of drugs based on living organisms are being discussed. Some of the mechanisms of probiotics influence on the immune system and aspects of clinical application of probiotics for preventing and treating dysbiosis, atopy, intestinal infections of bacterial and viral, cardiovascular, cancer and secondary immunodeficiencies, are highlighted. The research paper contains the possibility of co-using probiotics as vaccination adjuvant.

Keywords: bacteriemic preparations, probiotics, dysbacteriosis, gen-modified strains, Subalinum, Bacillus, probiotic therapy.

This review describes advances in molecular aspects of EBV infection
and disease. We discuss the spectrum of clinical illness due to EBV persistent infection. The main characteristic of Epstein-Barr virus (EBV) is that initial infection results in lifelong persistence. EBV infects nearly all humans by the time they reach adulthood. Healthy humans have approximately 1 to 50 infected cells per million leukocytes. EBV is one of the eight known human herpesviruses. EBV virions have a double-stranded linear DNA and 100 genes had been described in virus genome. Initial infection is thought to occur in the oral compartment. The host cells of EBV are mainly lymphocytes and epithelial cells. EBV attaches to B cells via binding of the viral gp350 protein to CD21 receptor. The consequence of EBV infection is cells proliferation and differentiation into memory B lymphocyte in the germinal center. Infected memory B cells are released into the peripheral circulation. EBV persists mostly in the memory B cell. Latency is the state of persistent viral infection without active viral production. In latently infected B cells EBV virus exist as episomes. During the latent phase episomal replication occurs via host DNA polymerase. Genes of the nuclear antigens (EBNA) and latent membrane proteins (LMP) are transcribed during latency. These include EBNA1, EBNA2, EBNA3A, EBNA3B, EBNA3C, EBNA leader protein (EBNALP), LMP1 and LMP2 genes. All nuclear antigens are transcription transactivators which bind to cis-regulatory DNA elements of cell or virus genomes directly or in complex with other proteins. LMP2A and LMP1 can function to coordinately mimic B-cell receptor and CD40 coreceptor signaling in latently infected B cells. LMP proteins activate cell signaling systems and as the consequence different gene expression programs. Characterization of gene expression patterns in different cell lines and pathologic conditions has revealed that there are at least three different latency programs. During I phase of latency latent EBV genomes can multiply in dividing memory B cells, during II phase of latency virus can induce and modulate B-cell differentiation, during III phase of latency virus can activate proliferation of the naïve B cells, during 0 phase of latency virus completely down regulates expression all protein coding genes. Latently infected B cells can occasionally be stimulated to reactivate EBV. Viral proteins BZLF1 and BRLF1 act as transactivators of the viral lytic program. The early reactivated virus gene products have such function as replication, metabolism and blockade of antigen processing. DNA polymerase replicates linear viral genome during the lytic phase. The late products code the structural proteins such as the viral capsid antigens (VCA) and gene products used for immune evasion. In healthy carriers virus exists in resting memory B lymphocytes in 0 phase of latency. The intensive virus reactivation in lytic replication phase or virus persistence in I, II and III latent phases promotes the development of such disease as lymphomas, rheumatoid arthritis, systemic erythematous lupus, chronic fatigue syndrome, etc. EBNA1 is expressed in the type I latency program, which is active in Burkitts lymphoma. EBNA1 and LMP1/2 are expressed in the type II latency program, which is observed in Hodgkins lymphoma. LMP1 and LMP2 expression activate proliferation program in the cell. The type III latency program, in which all of the latency gene products are expressed, is often detected during acute infectious mononucleosis or in virus infected B cell line and in inimmunocompromised individuals after tissue transplantation. Immunodeficiency-related B-cell posttransplant lymphoproliferative disorders (PTLDs) are caused directly by EBV. Chronic active EBV (CAEBV) infection develops due to the inappropriate viral load. This disease is characterized by chronic infectious mononucleosis-like symptoms with illness lasting for 6-24 months and in the course of the disease lymphoproliferative disorders like T or NK cell lymphomas may arise. The determined pattern of latent gene expression during CAEBV is latency type II. In this review we sum up the existing data linking EBV with rheumatoid arthritis and systemic erythematous lupus. SLE patients have abnormally high expression of several viral mRNAs coding for BZLF1, gp350, viral IL10, LMP1, LMP2 and EBNA1. So during this pathology EBV persists in litic and in latent phases. Also it has been demonstrated the humoral response to both latent and lytic EBV antigens in both sera and synovial fluids from patients with rheumatoid arthritis. Chronic Fatigue Syndrome (CFS) is characterized by severe fatigue with typical, cognitive dysfunctions and flu-like symptoms. Numerous studies find evidence for an association of CFS with EBV. In a subset of patients CFS begins with infectious mononucleosis. Elevated antibodies against EBV dUTPase and DNA polymerase has been found in CFS patients but not in controls Consistent with these data, elevated titers antibodies to ZEBRA detected in CFS patients. These data suggest that during CFS virus reactivate and enter in lytic replication. But according to other reports EBV virus in CFS patients replicates only latently. So, in the articles we summarized the data which reveal the connection between the disease development, phase of persistence and the program of gene expression.

Key words: Epstein-Barr virus, persistence, virus lytic replication, phase of latency, chronic active EBV infection.

The modern view of the etiology and treatment of pelvic pain in young women with genitals inflammation
Chernyakova A. M., Kosilova O. Yu, Dobrovol'skaya L. A.

Sensitive issue of modern gynecology can be considered widespread and substantial "rejuvenation" of inflammatory diseases of the pelvic organs in women of reproductive age.Ascending path of infection prevails in the pathogenesis of inflammatory diseases of the internal genital organs. Invasion of microbes in the internal genital organs may occur during the various manipulations, different pelvic operations and in the postpartum period. The degree of colonization of microorganisms of the vagina and cervix plays an important role in the development of the infectious process. In obstetrics and gynecology inflammatory diseases can be caused by pathogenic and non- pathogenic (opportunistic) microorganisms. Among the pathogens causing the defeat of the female genital organs, most often found N. gonorrhea, C. trachomatis, T. vaginalis. Opportunistic pathogens, part of the normal flora of the genital tract, in certain circumstances, can become agents of post-partum, post-abortion, post-operative complications and inflammatory diseases of the female genital organs. Among the opportunistic pathogens that are part of the normal microflora of the female genital organs, found hemolytic and non-hemolytic streptococci (the most important are streptococci groups A, B, D), coagulase-negative staphylococci and micrococci (allocated 60% and 35% of healthy women, respectively). They can cause secondary infectious processes of the urinary system, inflammatory diseases of the genital organs of pregnant women and mothers with immunosuppression. These microorganisms are often the agents of inflammatory diseases in the newborn, especially with low weight and malnutrition children. Gram-negative opportunistic bacteria that are isolated from the genital tract, can also be agents of inflammatory processes of various localization. Escherichia coli is the most frequently obtain and cause urinary tract infection in pregnant and postpartum women. It is also causative agent of postpartum sepsis and postoperative peritonitis. Among other gram-negative bacteria should be noted genus Klebsiella. Therefore, therapy of inflammatory diseases of the pelvic organs high demands due to the risk that represents this state to the reproductive function of patients. The mixed nature of the infection, the increasing rates of resistance of pathogens to antibiotics creates difficulties in selecting antimicrobial therapy, which remains the empirical till now. The inclusion of specific bacteriophages and plant antiseptics in therapeutic regimens for local treatment of inflammatory diseases of the vagina associated with an excessive colonization of the vaginal mucosa by aerobic opportunistic bacteria justified and can serve as an alternative to the traditional antibiotic therapy. All this determines the necessity for further studying the etiology and pathogenesis of infectious and inflammatory complications, the development of new highly effective methods of prevention and treatment.

Key words: inflammatory diseases, antimicrobial treatment, harmons, women reproductive system, dismenorrhea.

Today the problem of microbial resistance to antibacterial agents becomes the global one. Antimicrobial drugs that are in the pharmaceutical market do not satisfy the needs of modern treatment regimens, particularly Hospital-acquired infections. Therefore, the search for new and effective means of this pharmacological group is an important task of medical chemistry. From the literature it is known that derivatives of [1,2,4]triazolo[4,3-a]pyrazine show a wide range of biological actions, including antimicrobial and fungicidal. This makes it relevant microbiological study of primary derivatives of [1,2,4]triazolo[4,3-a]pyrazine for identifying promising compounds of the series and then study it in biological experiment.Using the PASS C&T (Prediction Activity Spectra for Substances: Complex & Training) program and based on published data, we have generated virtual library of derivatives of [1,2,4]triazolo[4,3-a]pyrazine. As a result, we have received 35 new synthetic compounds of 7 series that were not previously described in the literature. Materials and methods. The research of antimicrobial and fungicidal activity of the synthesized compounds was carried out in the laboratory of antimicrobial agents GA "Mechnikov Institute of microbiology and immunology" under the leadership of PhD, senior scientist V.V.Kazmirchuka. The activity of the synthesized compounds were studied by conventional method of the two-fold serial dilutions in liquid and solid nutrient medium. For primary screening we have used a set of clinical and reference strains of microorganism: Escherichia coli ATCC 25922 (F-50), Staphylococcus aureus ATCC 25923 (F-49), Bacillus anthracoides ATCC 1312, Pseudomonas aeruginosa ATCC 27853, Candida albicans ATCC 885-653. As the reference preparations were chosen Palin - modern antimicrobial agent of class of fluoroquinolones, Nevigramon - nalidixic acid derivative and Fluconazole - modern antifungal agent. Activity of substances determined by the minimum bacteriostatic (MBstK) and minimal bactericidal (MBcK) concentrations. All experiments were accompanied by appropriate controls. Results and Discussion. As a result of microbiological screening of 35 compounds we have allowed to identify a number of derivatives of [1,2,4]triazolo[4,3-a]pyrazine-8(7H)-one with antimicrobial and antifungal activity. The most pronounced effect showed compounds that contains in their structure aryl moiety with halogen atom, or N-arylatsetamide group in position 3 or 2 of the heterocycle. Principal condition for the demonstration of antifungal activity is presence of Sulfur atom in the triazole cycle. Conclusions. The substance of the series N7-aryl/benzyl-3-thioxo-[1,2,4] triazolo[4,3-]pyrazin-8(7H)-ones showed the best antimicrobial and antifungal activity of all synthesized compounds. Compound 7-(3-chloro-2-methyl-phenyl)- 3-thioxo-[1,2,4]triazolo[4,3-]pyrazin-8(7)-one 4{4} showed high values ​​of antimicrobial activity against gram-negative microorganisms (Bst 12.5-25.0 mkg/ml, Bc 25.0-50.0 mkg/ml) and was the most promising for further development.

Key words: [1,2,4]triazolo[4,3-a]pyrazin-8(7H)-one derivatives, antimicrobial activity, antifungal activity.

Introduction. Last decades, antimicrobial peptides (AMPs) are the subject of intense investigations aimed to develop effective drugs against extremely resistant nosocomial bacterial pathogens (especially Gram-negative bacteria). In particular, there has been greatly renewed interest to polymyxins, the representatives of AMPs which are specific and highly potent against Gram-negative bacteria, but have potential nephrotoxic side effect. A prerequisite of purposeful enhancement of therapeutic properties of polymyxins is a detailed knowledge of the molecular mechanisms of their interactions with cell targets. Lipopolysaccharide (LPS), the main component of the outer leaflet of outer membrane of gram-negative bacteria, is a primary cell target of polymyxins. The aim of the paper was to study the peculiarities of molecular interactions of polymyxin 3 with lipopolysaccharide of the outer membrane of gram-negative bacterium. Materials and methods. The complexes of polymyxin 3 (Pm3) and its alanine-derivatives with E. coli outer membrane lipopolysaccharide were built and studied by molecular modeling methods (minimization, simulated annealing, docking). Atom coordinates of polymyxin 3 and LPS structures were taken from nuclear magnetic resonance and X-ray crystallography experiments, respectively. The AMBER03 force field was used with a 1.05 nm force cutoff. Longrange electrostatic interactions were treated by the Particle Mesh Ewald method. Results and discussion. Alanine scanning of Pm3 molecule has been carried out and the role of its side amino acid residues in the formation of complex with lipopolysaccharide has been investigated. It has been shown that substitutions of polymyxins Dab residues in positions 1, 3, 5, 8 and 9 for alanine markedly reduce the binding energy of PmB3-LPS complex, where as the similar substitutions of residues in positions 2, 6, 7 and 10 leave the binding energy virtually unchanged. Structural aspects of antimicrobial action of polymyxins have been analyzed. Changes of minimal inhibitory concentrations (MIC) of alanine-derivatives of polymyxin and binding energies in dependence on the alanine substituent position were parallel, except Ala2- Pm3 mutant. Conclusions. Polymyxins side Dab residues, especially Dab1, Dab5, Dab 8 and Dab9, essentially contribute to the energy of polymyxin 3 binding with LPS of the outer membrane. Contribution of the others polymyxins side residues to the binding energy of the complex of polymyxin 3 with LPS was insignificant.

Key words: polymyxin, lipopolysaccharide, alanine scanning, binding energy

Introduction. Currently the priority goal of designing drugs is the integration of the methods of organic chemistry and pharmacology. The application of computer programmes which can predict interaction of potential drugs with molecules of biological targets makes possible to decrease the number of experiments on laboratory animals. Thereby the economic efficiency of production of new medicines increases. Models of the research the anticonvulsant activity (in particular, korazol, thiosemikarbazid, strychnine, etc.) are the most rigid experimental models of pharmacological screening, which basically entails the pains of laboratory animals or their death. The application of computer programmes in the research of potential anticonvulsants has economic and social desirability and high level of importance for the pharmaceutical science and health care. The most perspective methods of research are the virtual screening, molecular docking. These methods allow to evaluate the affinity of a substance to a specific biological target, i.e. to identify an inhibitor of a particular enzyme or protein. Material and methods. We have carried out the construction of 50 groups substances (507 hypothetical structures). We have chosen the five-membered di(three)azaheterocycle as basic pharmacophores to form virtual structures because firstly their structure is similar to cyclic conformation of neurotransmitter and secondly according to the literature perspective anticonvulsants had already found among these derivatives. Computer prediction of pharmacological activity for all compounds of virtual database was performed using the PASS (Prediction of Activity Spectra for Substances) computer programme. Results obtained by PASS-computer programme showed prospects of search the anticonvulsants among 10 groups of derivatives di(three)azaheterocycles (probable activity (Pa) of substances of these groups are from 0.5 to 0.84). In order to determine the potential anticonvulsant activity of 1,2,3(1,2,4)triazole, 1,3,4-oxa(thia)diazole we investigated the mechanisms of action that involve the interaction of the ligand NMDA-, GAMKA- or glutamate receptors and GABA-AT ligand-enzyme. We have perfomed docking research for our structures and for known anticonvulsants using the Fast Dock method, in which both protein and ligand are rigid (Software SCIGRESS; Fujitsu, Fukuoka, Japan). We have evaluated affinity of the investigated structures with molecules biotargets: GABAA receptor protein (PDB code 1GNU), glutamate receptor protein Glu-1 (PDB code 1EWK), GluN1 NMDA receptor protein (PDB code 3Q41) and protein enzyme GABA-AT (PDB code 1OHW). Results and discussion. As a result, we have obtained the values of ​​scoring functions Consensus, which enabled to evaluate affinity compounds and biological anticonvulsant targets and identify 11 perspective groups of compounds (number of compounds 190) that can selectively inhibit NMDA, a GABA - or glutamate receptors and GABA aminotransferase enzyme in comparison with known anticonvulsant drugs. The number of active groups of the results PASS prediction according to the obtained results is 10 (the number of compounds 168). It should be noted that result of docking research coincided with the results of PASS prediction for eight groups of compounds. Conclusion . 1. Eleven groups of compounds derivatives of 1,2,3(1,2,4) -triazols, 1,3,4-oxadiazoles and 1,3,4- thiadiazoles was selected for further screening as perspective anticonvulsants; 2. GABA-ergic mode of action for 8 groups of derivatives and glutamatergic mode of action for 3 groups of derivatives five-membered di(three)azaheterocycle was predicted.

Keywords: docking, anticonvulsant activity, PASS computer program, di (three) azaheterocycle.

This paper presents data on screening of antimicrobial properties of extracts from some kinds of raw materials (18 plants) with hydroquinone, naphtoquinone or anthraquinone derivatives. Some technological parameters of extracts (density and concentration of extraneous substances) have been determined. The most appropriate microbiological method of studying antimicrobial properties of extracts, diffusion method of well, has been applied; special mathematic method of comparison of antimicrobial properties of extracts vector analysis has been applied in order to study and to compare antimicrobial properties of extracts. Indexes of antimicrobial properties of extracts have been determined: a complex index of medicinal product antimicrobial activity for quantitative estimation of antimicrobial effect - A, and square of correlation coefficient - r², which demonstrates the spectrum of antimicrobial activity of the extracts (degree of similarity to the standard). The most active extracts have been selected; they have antimicrobial properties of medium strength: from the herb of chimaphila umbellata
=2.20; the fruits of rhamnus cathartica =2.12; the root of rubia tinctorum =2.11; the bark of frangula alnus =2.05; the root of rumex confertus =2.04; the leaf of pyrola rotundifolia =2.00; and leaf of arctostaphylos uva-ursi =2.08 (but extract from uva-ursi did not affected on 2 strains of microorganisms r²=0.64). Low levels of antimicrobial activity have been demonstrated by the extract obtained from the leaf of urtica dioica =0.72, r²=0.34. The mean result of the complex index of antimicrobial activity for the most of extracts from plants containing quinonederivatives is A = 1.77 (on 70% vol. ethanol at a ratio of raw material : extracting agent 1:7 wt. : vol.) and may range from 0.68 to 2.85. The mean result of the correlation coefficient is r = 0.93 and may range from 0.59 to 0.99. The mean result of the concentration of extractives in extracts is C = 0.0386 g/g extract and may range from 0.0017 to 0.0755 g/g extract. The mean result of the extract density is ρ = 0.897 g/cm³ and may range from 0.877 to 0.917 g/cm³. It is noted antimicrobial properties of the solution of alizarin 0.1% m / m in 70% vol. ethanol, which in studies showed moderate strength antimicrobial properties: A = 1.60 and inhibited the growth of all tested strains of microorganisms r=0.99. This potentially allows to predict the antimicrobial properties of extracts from plants containing derivatives of alizarin on its concentration in them. Study data show significant antimicrobial properties of numerous kinds of raw materials that contain of hydroquinones, naphtoquinones, anthraquinones and high possibility of their use in complex phytochemical medicinal products as antimicrobial component.

In the therapy of decompensated form of chronic tonsillitis (CT) were used as immunomodulatory agents IRS and Ismigen. These bacterial lysates differ in the bacterial setting, the method of preparation (chemical, mechanical) and the method of application.Rheumatoid arthritis (RA) is one of the important factors that could significantly complicate the therapy of chronic tonsillitis. RA is a chronic immune inflammatory disease that progressively affects connective tissue mostly of the peripheral joints and it has a wide range of extra-articular manifestations. The aim of our study was to explore the dynamics of immunologic indicators during the active disease and treatments in patients with decompensate form of chronic tonsillitis, including tonsillitis complicated with RA. Materials and methods. 33 patients with decompensate form of chronic tonsillitis in active period of disease observed during the study. Patients were divided into the following groups: 24 persons with the decompensate form of CT, 9 persons with the rheumatoid arthritis and 9 persons with the decompensate form of CT complicated with RA in remission stage. The control group consisted of 15 apparently healthy persons. Concentrations of serum IgA, IgM, IgG were determined by the method of radial immune diffusion by Manchini. Levels of sIgA, IFN γ and rheumatoid factor in the blood serum of patients were evaluated using ELISA test systems of "Vector-best". Patients of group CTD (with decompensate form of chronic tonsillitis) were divided into subgroups CTD1 and CTD2, depending on the applied treatment. Both subgroups treated with standard therapy for two weeks and received Derynat during 1 month by 2 drops in each nostril twice a day. After 30 days of the standard therapy beginning the subgroup CTD1 patients received IRS 19 during two weeks, one intranasal inhalation in each nostril 3 times a day. Patients subgroup CTD2 and CTD+RA instead IRS 19 received Ismigen after 30 days of the beginning of the standard therapy, during 10 days, sublingually 1 per day.Patients with RA were at the stage of clinical remission and do not receive basic disease-modifying drugs for at least 6 months after the last course of therapy. The effectiveness of the treatment was assessed by the general state of the patients according to oropharyngoscopy, concentration of IgA, IgM, IgG and IFN-γ in serum and sIgA in pharynx secret after 45 days of observation.Antibodies to microbial antigens (antistreptolysin O-hemolytic streptococci) were determined before treatment and after 45 days using passive hemagglutination reaction.Statistical analysis of the results was performed using the Mann-Whitney U test. According to the accepted level of reliability index value between the groups (p), which constituted or were less than 0.05. Results and discussion. 1. In all groups before treatment was determined deficiency of humoral immunity. The level of sIgA was significantly reduced relative to controls as in patients with exacerbation of decompensate form of chronic tonsillitis with RA (CTD + RA group) and in the group with chronic tonsillitis without RA (CTD group). The level of IgG before treatment group CTD + RA was significantly elevated relative CTD group, the comparison group (patients with RA without tonsillitis) and the control group.2. Preparations Ismigen and IRS 19 demonstrated high efficacy as immune modulatory agents in the treatment of decompensate form of chronic tonsillitis in the acute stage. Combined with Derynat use of these drugs after standard therapy allowed to normalize humoral immunity. In the subgroup of patients which received Ismigen level of sIgA after 45 days was significantly higher with respect to the subgroup that received IRS 19. These differences may be related both to the various quantitative and qualitative antigenic composition of the drug, and the difference in the method and circuit their application and in accordance with the bioavailability of the components of bacterial lysates.3. atients at CTD + RA before treatment is characterized by elevated levels of ASO for the group CTD. ASO level was significantly higher than normal level in CTD and CTD + RA groups.4. Application of bacterial lysates containing antigens of hemolytic streptococci, such as Ismigen or IRS 19, does not cause increase level of ASO and rheumatoid factor in all groups of patients, indicating an insufficient level of immunogenicity of these drugs to influence the course of RA in the inactive phase of the disease.

Keywords: immunity, chronic tonsillitis, rheumatoid arthritis, immunoglobulins, bacterial lyzates.

The rapid decrease in sensitivity of pathogens septic infections to antimicrobial agents has led to significant difficulties in the fight against antibiotic-resistant infections even in developed countries. One solution to this problem is a method of combining antimicrobial different pharmacological groups. The most promising for combination drugs are derivatives of phosphonic acids, which are able to deeply penetrate biological film and microbial cells and enhance the antibacterial action of other antibiotics. A study of the effectiveness of combination antibiotic fosfomycin with cefepime and fosfomycin with tiename on polyantibiotic-resistant strains Pseudomonas aeruginosa. Set the antibiotic used in the experiments performed by P.aeruginosa strains of "serial dilutions" and the disco-diffusion method. The efficacy of combinations of antibiotics was carried out by determining the minimum inhibitory concentrations routine method in vitro method "checkerboard". The results of experimental studies the combination of cefepime on multiresistant strains Fosfomycin on Pseudomonas aeruginosa show a significant decrease in the MIC of cefepime in combination on ten of the thirteen strains. MIC Fosfomycin significantly decreased relative to the nine strains. In calculating the index FIX appears that a synergistic effect of the combination of antibiotics studied (FIX ≤ 0,5) was observed on 69.2% of the subjects strains of P.aeruginosa. In experiments on three strains observed effect summation antimicrobial antibiotics specified combinations (FIX> 0,5, ≤ 1,0), one strain - indifferent effect (FIX> 1.0). You can also combined fosfomycin with tiename significant (greater than 2-fold) reduction in MIC these antibiotics was observed only for 2 subjects cultures P. aeruginosa. Calculation of the FIX showed that combined use of fosfomycin with tiename created largely indifferent effect refers to the strains of P. aeruginosa. Thus, studies have shown a high degree of synergy combination of fosfomycin with cefepime on polyantibiotic-resistant strains strains of P. aeruginosa.

Keywords: combinations of the antibiotics, polyantibiotic-resistant strains, checkerboard method.
