Abstract
We studied the possibility of using 4-hexylresorcinol to increase the efficiency of anti-mycobacterial chemotherapy. In an in vitro experiment, 4-hexylresorcinol increased the efficiency of rifampicin, kanamycin, and isoniazid against Mycobacterium smegmatis by 3-5 times. Experiments in sanitation of BALB/c mice infected with M. smegmatis showed the best efficacy of the isoniazid and 4-hexylresorcinol combination in comparison with isoniazid monotherapy. The growth-inhibiting activity of the combination of antibiotic rifabutin with 4-hexylresorcinol was shown on 6 strains of M. tuberculosis. A 2-fold decrease in the minimum inhibitory concentration of this antibiotic in the presence of half-minimum inhibitory concentration of 4-hexylresorcinol was demonstrated for monoresistant strain M. tuberculosis 5360/42Hr. On the mouse model of experimental tuberculosis caused by M. tuberculosis H37Rv, a 5-fold decrease in lung contamination and more rapid complete cure were achieved in animals treated with the combination of rifabutin and 4-hexylresorcinol in comparison with rifabutin monotherapy.

Abstract
Dormant forms of causative agents of healthcare-acquired infections Moraxella catarrhalis and Kocuria rhizophila have been obtained. Dormant forms cells retained viability during long-term storage (≈107 CFU/ml after 2 months) under provocative conditions (lack of nutrient sources; temperature 20°C, oxygen access) were characterized by heat resistance, and acquired special ultrastructural organization typical of dormant forms (compacted nucleoid, thickened cell wall). They were also capable of forming alternative phenotypes (dominant and small colony variants) in a new cycle of germination in a fresh medium. These results demonstrate that the dormant forms can be responsible both for survival in the environment and persistence in the host organism.

Abstract
The new coronavirus infection COVID-19 is an acute viral disease that affects primarily the upper respiratory tract. The etiological agent of COVID-19 is the SARS-CoV-2 RNA virus (Coronaviridae family, Betacoronavirus genus, Sarbecovirus subgenus). We have developed a high-affinity human monoclonal antibody, called C6D7-RBD, which is specific to the S protein receptor-binding domain (RBD) from the SARS-CoV-2 Wuhan-Hu-1 strain and exhibits virus-neutralizing activity in a test with recombinant antigens: angiotensin-converting enzyme 2 (ACE2) and RBD.

Abstract
The purpose of this work was to obtain genus-specific monoclonal antibodies against the Legionella spp. recombinant PAL protein, which will subsequently allow to use them as a basis for the development of new express tests for pathogenic legionella detection. A short three-week immunization protocol for Wistar rats was used to generate rat-mouse heterohybridomas producing antibodies against PAL. Mouse myeloma cell line Sp2/0-Ag14 served as the fusion partner. Hybridization was performed using two methods: PEG-mediated fusion and electrofusion. Subsequent screening was performed by indirect solid-phase ELISA against the target protein rPAL. Specificity analysis was performed by dot-blot using a panel of lysates obtained from 39 pure cultures of different strains, which included closely related and heterologous microorganisms among others. No difference in the efficiency of stable hybridoma clones production by the two indicated cell-fusion methods was detected. Twelve clones producing specific rat monoclonal antibodies were obtained based on the screening results. The obtained rat monoclonal antibodies are highly specific towards the PAL protein of L. pneumophila of different serological groups and other pathogenic legionella and are good candidates to be used as the components of diagnostic test systems for the detection of pathogenic representatives of the Legionella genus.

Abstract
Neutralization of the lethal toxin of Bacillus anthracis is an important topic of both fundamental medicine and practical health care, regarding the fight against highly dangerous infections. We have generated a neutralizing monoclonal antibody 1E10 against the lethal toxin of Bacillus anthracis and described the stages of receptor interaction between the protective antigen (PA) and the surface of eukaryotic cells, the formation of PA oligomers, assembly of the lethal toxin (LT), and its translocation by endocytosis into the eukaryotic cell, followed by the formation of a true pore and the release of LT into the cell cytosol. The antibody was shown to act selectively at the stage of interaction between Bacillus anthracis and the eukaryotic cell, and the mechanism of toxin-neutralizing activity of the 1E10 antibody was revealed. The interaction between the 1E10 monoclonal antibody and PA was found to lead to inhibition of the enzymatic activity of the lethal factor (LF), most likely due to a disruption of true pore formation by PA, which blocks the release of LF into the cytosol.

Abstract
High efficiency of a combined preparation including synergistic polymyxin B and 4-hexylresorcinol was shown for treatment of experimental sepsis caused by an antibiotic-resistant highly virulent hypermucoid Klebsiella pneumoniae strain KPM9Pmr in mice. Complex therapy with polymyxin B (1 mg/kg) and 4-hexylresorcinol (30 mg/kg) led to cure in 80%; in 20% of these mice, no bacterial cells were found. After treatment with polymyxin B alone, only 50% animals survived and all of them contained bacterial cells. Comparative analysis of the results of monotherapy and combined treatment indicates that 4-hexylresorcinol not only increases the efficiency of antibiotic, but also minimizes persistence of the infection agent and therefore, the risk of development of antibiotic resistance.

Abstract
This review presents various strategies to fight causative agents of infectious diseases. Species-specific programmable RNA-containing antibiotics open up new possibilities for creating next-generation of personalized drugs based on microbiome editing and can serve as a new tool for selective elimination of pathogenic bacterial species while keeping intact the rest of microbiota. Another promising approach in combating bacterial infections is genome editing using the CRISPR-Cas systems. Expanding knowledge on the molecular mechanisms of innate immunity has been actively used for developing new antimicrobials. However, obvious risks of using antibiotic adjuvants aimed at activation of the host immune system include development of the autoimmune response with subsequent organ damage. To avoid these risks, it is essential to elucidate action mechanisms of the specific ligands and signal molecules used as components of the hybrid antibiotics. Bacteriophage endolysins are also considered as effective antimicrobials against antibiotic-resistant bacteria, metabolically inactive persisters, and microbial biofilms. Despite significant advances in the design of implants with antibacterial properties, the problem of postoperative infections still remains. Different nanomodifications of the implant surface have been designed to reduce bacterial contamination. Here, we review bactericidal, fungicidal, and immunomodulating properties of compounds used for the implant surface nanomodifications, such as silver, boron nitride nanomaterials, nanofibers, and nanogalvanic materials.

Abstract
Ever decreasing efficiency of antibiotic treatment due to growing antibiotic resistance of pathogenic bacteria is a critical issue in clinical practice. The two generally accepted major approaches to this problem are the search for new antibiotics and the development of antibiotic adjuvants to enhance the antimicrobial activity of known compounds. It was therefore the aim of the present study to test whether alkylresorcinols, a class of phenolic lipids, can be used as adjuvants to potentiate the effect of various classes of antibiotics. Alkylresorcinols were combined with 12 clinically used antibiotics. Growth-inhibiting activity against a broad range of pro- and eukaryotic microorganisms was determined. Test organisms did comprise 10 bacterial and 2 fungal collection strains, including E. coli and S. aureus, and clinical isolates of K. pneumoniae. The highest adjuvant activity was observed in the case of 4-hexylresorcinol (4-HR), a natural compound found in plants with antimicrobial activity. 50% of the minimal inhibitory concentration (MIC) of 4-HR caused an up to 50-fold decrease in the MIC of antibiotics of various classes. Application of 4-HR as an adjuvant revealed its efficiency against germination of bacterial dormant forms (spores) and prevented formation of antibiotic-tolerant persister cells. Using an in vivo mouse model of K. pneumoniae-induced sepsis, we could demonstrate that the combination of 4-HR and polymyxin was highly effective. 75% of animals were free of infection after treatment as compared to none of the animals receiving the antibiotic alone. We conclude that alkylresorcinols such as 4-HR can be used as an adjuvant to increase the efficiency of several known antibiotics. We suggest that by this approach the risk for development of genetically determined antibiotic resistance can be minimized due to the multimodal mode of action of 4-HR.

Abstract
The results of the comparative testing of the susceptibility of M. tuberculosis clinical strains to isoniazid, streptomycin, rifampicin and ethambutol using the TB test kit, developed in SCRAMB, (Obolensk) and the absolute concentrations method; the TB test kit and the BACTEC MGIT 960 automated system are presented in the study. A total of 629 and 220 strains, respectively, were tested. A high degree of agreement of the results was shown: 89.1-98.6% for isoniazid, 96.2-98.0% for rifampicin, 91.5-98.2% for streptomycin and 89.1-95.9% for ethambutol. The smallest number of discrepancies in the results was obtained when comparing the TB test kit and BACTEC MGIT 960. The discrepant results analysis was performed by the proportion method, PCR sequencing, or re-testing on new lots of the TB test kit and Lowenstein-Jensen medium with anti-tuberculosis drugs, after which the sensitivity, the specificity and the efficiency of the TB test kit have exceeded 95 % for all anti-tuberculosis drugs. The turnaround time with the TB test kit (median 9.25-9.9 days, ranged from 8 to13 days) was significantly shorter than that with the absolute concentration method (median 21-23 days, ranged from 20 to 28 days) and is commensurate with the turnaround time with BACTEC MGIT 960 (average 7.2 days, ranged from 5 to 12 days). The TB test kit is easy to use, does not require expensive equipment and special staff training.

Abstract
Aptamers are short single-stranded oligonucleotides which are selected via targeted chemical evolution in vitro to bind a molecular target of interest. The aptamer selection technology is designated as SELEX (Systematic evolution of ligands by exponential enrichment). SELEX enables isolation of oligonucleotide aptamers binding a wide range of targets of interest with little respect for their nature and molecular weight. A number of applications of aptamer selection were developed ranging from biosensor technologies to antitumor drug discovery. First aptamer-based pharmaceutical (Macugen) was approved by FDA for clinical use in 2004, and since then more than ten aptamer-based drugs undergo various phases of clinical trials. From the medicinal chemist’s point of view, aptamers represent a new class of molecules suitable for the development of new therapeutics. Due to the stability, relative synthesis simplicity, and development of advanced strategies of target specific molecular selection, aptamers attract increased attention of drug discovery community. Difficulties of the development of next-generation antibiotics basing on the conventional basis of combinatorial chemistry and high-throughput screening have also amplified the interest to aptamer-based therapeutic candidates. The present article reviews the investigations focused on the development of antibacterial aptamers and discusses the potential and current limitations of the use of this type of therapeutic molecules.

Abstract
Category A select agents continue to be major threat to human population both as naturally occurring diseases and as potential weapon of bioterrorists. Anthrax and botulism are probably the most threatening agents as both have virtually uncontrolled natural reservoirs from which they can be isolated and propagated. Available specific antitoxin therapy of both diseases is outdated; its efficiency is questionable as well as safety of reactogenic or human-derived components used in treatment. Highly sensitive toxin detection techniques are still not as widespread as it needed for timely alerting medical services. There is urgent need of pre-exposure prophylaxis and postexposure specific antitoxin therapy for anthrax and botulism. Analysis of modern studies in the field suggests oligoclonal antibodies acting against receptor-binding toxin subunits and nucleic acid aptamers as allosteric inhibitors of metlloproteolytic toxin components as the most promising candidates for development of efficient antitoxin therapy.

Abstract
Most multidrug-resistant (MDR) Mycobacterium tuberculosis isolates in Russia belong to the Beijing or Latino-American and Mediterranean (LAM) spoligotype families. The objective of this study was to investigate possible associations between genotype and the frequencies of mutations that confer drug resistance in a population that has two large families of circulating strains. Spoligotyping, IS6110 restriction fragment length polymorphism typing, and sequencing of the katG and rpoB genes, were performed for 217 consecutive MDR M. tuberculosis isolates from patients. The rpsL and rrs genes were also sequenced for selected streptomycin-resistant isolates. Of the 217 MDR isolates, 99 (46%) belonged to the LAM family, 92 (42%) to the Beijing family, 21 (10%) to the Haarlem family and four (2%) to the T family. There was one unique spoligotype. Mutations in the katG gene were identified in 207 (95%) isolates, all of which had mutations in codon 315. Mutations in the rpoB gene were identified in 200 (92%) isolates; 75% of LAM isolates carried a mutation in codon 516, whereas 71% of Beijing isolates carried a mutation in codon 531. In the 33 isolates resistant to streptomycin 50 mg/L, the 43AGG rpsL mutation was found in 27% of Haarlem, 75% of Beijing and 0% of LAM isolates, and rrs mutations were found in 17% (516C-->T) of Beijing and 100% (513A-->C) of LAM isolates. Overall, there appeared to be a correlation between the genotype and specific mutations conferring resistance to rifampicin or streptomycin in the Beijing and LAM families. The biological implications of this correlation remain to be explored.

Abstract
We studied the effects of alpha1-acid glycoprotein preparations on the survival rate of BALB/c mice infected with the lethal dose of B. anthracis STI-1. Apart from native alpha1-acid glycoprotein from donor blood, we studied 3 glycoforms differing in the affinity for concanavalin A and structure of carbohydrate chains. The protective effect of alpha1-acid glycoprotein preparations did not depend on its dose and was observed 3 months after treatment (0.3 mg per mouse). The protective effect was revealed in mice receiving alpha1-acid glycoprotein preparations 2 h before infection and 24 h after inoculation of the bacterial culture. In the latter case the survival rate of animals was much higher compared to that observed in preventive administration of alpha1-acid glycoprotein. The protective effect practically did not depend on the time of treatment with glycoforms. Pretreatment with alpha1-acid glycoprotein preparations significantly decreased plasma interferon-gamma concentration. Administration of the test preparations 24 h after infection decreased the concentration of tumor necrosis factor-alpha.

Abstract
SETTING Tuberculosis ward of a prison in Russia. OBJECTIVE Molecular characterization of drug-resistant isolates. DESIGN Isolates were collected from all tuberculosis patients occurring in the prison over a 1-year period. RESULTS Of 130 patients studied, 17 patients produced pan-susceptible isolates and 113 produced isolates resistant to at least one drug, including 85 multidrug-resistant isolates. Mutations at katG315 occurred in 98% of isoniazid-resistant isolates. Mutations in rpoB were found in 89% of rifampicin-resistant isolates. Mutations in pncA occurred in 13% of the 75 isolates tested. By spoligotyping, members of the Beijing (55 isolates) and LAM (31 isolates) families were identified. By IS6110 genotyping, two groups (34 and 55 isolates) of related isolates were found, including three clusters (10, 12, and 16 isolates) with identical patterns. In a study of samples collected 3 months apart from 28 patients, four patients produced isolates containing a mixture of strains and five patients produced specimens containing distinctly different isolates. Isolates of nine patients acquired additional drug resistance. CONCLUSION Three families of strains accounted for much of the drug-resistant tuberculosis in this population. Multiple resistance, acquisition of resistance, and infection with two or more strains as well as reinfection were observed.

Abstract
We studied the effects of alpha1-acid glycoprotein on tumor necrosis factor-alpha (TNF-alpha) and interleukin-10 (IL-10) production and lymphocyte response to phytohemagglutinin in cultured peripheral blood mononuclear leukocytes from 6 healthy donors. We observed 2 opposite responses to alpha1-acid glycoprotein: first, stimulation of TNF-alpha and IL-10 production and inhibition of lymphocyte proliferation, and second, suppression of cytokine production and stimulation of lymphocyte proliferation. In cell cultures isolated from 4 of 6 donors, the TNF-alpha/IL-10 ratio remained unchanged after addition of native alpha1-acid glycoprotein, but some fractions isolated by chromatography on concanavalin A-Sepharose changed this parameter. These changes were most pronounced after treatment with fraction C enriched with molecules with incomplete (biantennary) carbohydrate chains. The mechanisms of alpha1-acid glycoprotein-induced effects on peripheral blood mononuclear leukocytes are discussed.

Abstract
SETTING State Research Center for Applied Microbiology, Russian Research Institute of Phthisiopulmonology (Ministry of Health, Moscow). OBJECTIVE To analyze drug-resistant clinical isolates of Mycobacterium tuberculosis obtained from patients referred to the institute from different parts of Russia, and to study the mechanisms of their rifampicin resistance. DESIGN Fifty clinical isolates of M. tuberculosis were analysed. Polymerase chain reaction (PCR) and sequencing were used to study the mechanisms of rifampicin resistance in 25 isolates. RESULTS Among cultures isolated from 50 patients, drug resistance was detected in 33. Most of the isolates were resistant to rifampicin (25 isolates), isoniazid (14 isolates), and streptomycin (seven isolates). Only 6% of the isolates were resistant to one drug, while 14% were resistant to two, 32% to three, 40% to four, and 8% to five drugs. Susceptible isolates were derived from 17 patients. The following point mutations and deletions in the rpoB locus, responsible for high level rifampicin resistance (more than 50 microg/ml in egg-based medium), were detected: G-->A/395 (Arg-->Gln), C-->T/232 (His-->Tyr), C-->T/221 (Ser-->Leu), G-->T/202 (Asp-->Tyr), GA-->TT/202-203 (Asp-->Phe), deltaATGGACCAG/199-207 (Met, Asp, Gin), A-->T/91 (Met-->Leu), TG-->CC/227-228 (Leu-->Ser), GAG-->AGT/349-350-351 (Gln-->Ser), deltaGGG/354(Gly). CONCLUSION A number of previously unrecognised genetic modifications in the rpoB region were found in rifampicin-resistant strains isolated from patients from different parts of Russia.
