910000.9976Unlocking the bacterial membrane as a therapeutic target for next-generation antimicrobial amphiphiles. Gram-positive bacteria like Enterococcus faecium and Staphylococcus aureus, and Gram-negative bacteria like Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter Spp. are responsible for most of fatal bacterial infections. Bacteria present a handful of targets like ribosome, RNA polymerase, cell wall biosynthesis, and dihydrofolate reductase. Antibiotics targeting the protein synthesis like aminoglycosides and tetracyclines, inhibitors of RNA/DNA synthesis like fluoroquinolones, inhibitors of cell wall biosynthesis like glycopeptides and β-lactams, and membrane-targeting polymyxins and lipopeptides have shown very good success in combating the bacterial infections. Ability of the bacteria to develop drug resistance is a serious public health challenge as bacteria can develop antimicrobial resistance against newly introduced antibiotics that enhances the challenge for antibiotic drug discovery. Therefore, bacterial membranes present a suitable therapeutic target for development of antimicrobials as bacteria can find it difficult to develop resistance against membrane-targeting antimicrobials. In this review, we present the recent advances in engineering of membrane-targeting antimicrobial amphiphiles that can be effective alternatives to existing antibiotics in combating bacterial infections.202134325929
974810.9976Resistance in antimicrobial photodynamic inactivation of bacteria. Antibiotics have increasingly lost their impact to kill bacteria efficiently during the last 10 years. The emergence and dissemination of superbugs with resistance to multiple antibiotic classes have occurred among Gram-positive and Gram-negative strains including Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa and Enterobacter strains. These six superbugs can "escape" more or less any single kind of antibiotic treatment. That means bacteria are very good at developing resistance against antibiotics in a short time. One new approach is called photodynamic antimicrobial chemotherapy (PACT) which already has demonstrated an efficient antimicrobial efficacy among multi-resistant bacteria. Until now it has been questionable if bacteria can develop resistance against PACT. This perspective summarises the current knowledge about the susceptibility of bacteria towards oxidative stress and sheds some light on possible strategies of the development of photodynamic inactivation of bacteria (PACT)-induced oxidative stress resistance by bacteria.201526098395
975220.9975Engineered Phages and Engineered and Recombinant Endolysins Against Carbapenem-Resistant Gram-Negative Bacteria: A Focused Review on Novel Antibacterial Strategies. Antibiotic resistance has escalated globally, affecting not only commonly used antibiotics but also last-resort agents such as carbapenems and colistin. The rise of antibiotic-resistant bacteria has prompted microbiologists to devise new strategies, with bacteriophages emerging as one of the most promising options. Nevertheless, certain mechanisms have been identified in bacteria that confer resistance to phages. While phage resistance is currently less widespread than antibiotic resistance, challenges such as biofilm formation, newly emerging resistance mechanisms against phages, and the natural limitations of unmodified phages have driven the advancement of engineered phages. This study aims to examine the efficacy of engineered phages and both engineered and recombinant endolysins against carbapenem-resistant Gram-negative bacteria (CR-GNB). We performed a literature review through PubMed, Scopus, Web of Science, and Google Scholar, concentrating on studies that utilized these agents against carbapenem-resistant Gram-negative bacteria (CR-GNB). Reviewed studies indicate potential antibacterial activity of these agents against CR-GNB. By engineering and modifying phages, these agents exhibit improved antimicrobial efficacy, temperature stability, and membrane permeability. Furthermore, they demonstrate the ability to eliminate bacteria with multidrug-resistant (MDR) and extensively drug-resistant (XDR) profiles. These findings suggest the promising potential of engineered phages and endolysins for future clinical applications against CR-GNB.202540696543
424630.9975Bacteriocins to Thwart Bacterial Resistance in Gram Negative Bacteria. An overuse of antibiotics both in human and animal health and as growth promoters in farming practices has increased the prevalence of antibiotic resistance in bacteria. Antibiotic resistant and multi-resistant bacteria are now considered a major and increasing threat by national health agencies, making the need for novel strategies to fight bugs and super bugs a first priority. In particular, Gram-negative bacteria are responsible for a high proportion of nosocomial infections attributable for a large part to Enterobacteriaceae, such as pathogenic Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa. To cope with their highly competitive environments, bacteria have evolved various adaptive strategies, among which the production of narrow spectrum antimicrobial peptides called bacteriocins and specifically microcins in Gram-negative bacteria. They are produced as precursor peptides that further undergo proteolytic cleavage and in many cases more or less complex posttranslational modifications, which contribute to improve their stability and efficiency. Many have a high stability in the gastrointestinal tract where they can target a single pathogen whilst only slightly perturbing the gut microbiota. Several microcins and antibiotics can bind to similar bacterial receptors and use similar pathways to cross the double-membrane of Gram-negative bacteria and reach their intracellular targets, which they also can share. Consequently, bacteria may use common mechanisms of resistance against microcins and antibiotics. This review describes both unmodified and modified microcins [lasso peptides, siderophore peptides, nucleotide peptides, linear azole(in)e-containing peptides], highlighting their potential as weapons to thwart bacterial resistance in Gram-negative pathogens and discusses the possibility of cross-resistance and co-resistance occurrence between antibiotics and microcins in Gram-negative bacteria.202033240239
979040.9975Emerging antibiotic resistance: carbapenemase-producing enterobacteria. Bad new bugs, still no new drugs. Antimicrobial resistance (AMR) is a global health security threat requiring actions across government sectors and society. Many factors are involved in this phenomenon, being overuse of antibiotics, incorrect antibiotic prophylaxis, and use of antibiotics for zootechnic reasons the main causes of the increasing rate of multi-drug resistant (MDR) bacteria. The impact of resistance to antimicrobials is an important threat due also to the emergence of MDR Gram-negative bacteria resistant to carbapenems, and the lack of the research for new active molecules. The production of extended spectrum beta-lactamase enzymes has been the first threatening mechanism for Gram-negative resistance to antibiotics, which prompted the development of new classes of antibiotics such as carbapenems. Unfortunately, resistance to carbapenems developed because of multiple mechanisms including efflux pumps, porin mutations and enzyme production, being the latter particularly relevant in terms of diffusion due to the genes located within plasmids that drive their horizontal diffusion. In this scenario, antimicrobial stewardship programs (ASP) are a mandatory resource in fighting the resistance spread. The reduction of total amount of antibiotics administration in the hospital setting and guiding prescribers in the correct administration of antibiotics for the smallest period possible, at the correct dosage, can be defined as the first goals of an ASP. Anyway, in an efficacious ASP, apart from antibiotic administration, efforts must been made in ensuring the lowest probability of spreading of MDR by efficacious measures of isolation of carriers, and by offering tools for a rapid diagnosis of viral infections avoiding the administration of unnecessary antibiotics. A continuous audit of the ASP programs and a correct assessment of the allergy to drugs such as penicillin have to complete the program. Currently, only a few options are available for patients with an infection sustained by Gram-negative MDR bacteria. All the options actually available are based on the administration of colystin, an old drug whose real efficacy is reduced due to its relevant toxicity, or on the administration of recently proposed drugs such as ceftolozane-tazobactam, ceftazidime-avibactam and meropenem-vaborbactam. All these new drugs do not have a novel mechanism of action and have limited spectrum in term of activity against MDR bacteria. In conclusion, antimicrobial resistance is a global emergence and AMP is the most powerful tool actually available. Few limited options are available to treat infections due to Carbapenem Resistant Enterobacteria. Antimicrobial molecules with true novel mechanism of action are needed to win the fight against antimicrobial resistance.201931846984
488350.9975New tools to mitigate drug resistance in Enterobacteriaceae - Escherichia coli and Klebsiella pneumoniae. Treatment to common bacterial infections are becoming ineffective of late, owing to the emergence and dissemination of antibiotic resistance globally. Escherichia coli and Klebsiella pneumoniae are the most notorious microorganisms and are among the critical priority pathogens listed by WHO in 2017. These pathogens are the predominant cause of sepsis, urinary tract infections (UTIs), pneumonia, meningitis and pyogenic liver abscess. Concern arises due to the resistance of bacteria to most of the beta lactam antibiotics like penicillin, cephalosporin, monobactams and carbapenems, even to the last resort antibiotics like colistin. Preventing influx by modulation of porins, extruding the antibiotics by overexpression of efflux pumps, mutations of drug targets/receptors, biofilm formation, altering the drug molecules and rendering them ineffective are few resistance mechanisms that are adapted by Enterobacteriaeceae upon exposure to antibiotics. The situation is exacerbated due to the process of horizontal gene transfer (HGT), wherein the genes encoding resistance mechanisms are transferred to the neighbouring bacteria through plasmids/phages/uptake of free DNA. Carbapenemases, other beta lactamases and mcr genes coding for colistin resistance are widely disseminated leading to limited/no therapeutic options against those infections. Development of new antibiotics can be viewed as a possible solution but it involves major investment, time and labour despite which, the bacteria can easily adapt to the new antibiotic and evolve resistance in a relatively short time. Targeting the resistance mechanisms can be one feasible alternative to tackle these multidrug resistant (MDR) pathogens. Removal of plasmid (plasmid curing) causing resistance, use of bacteriophages and bacteriotherapy can be other potential approaches to combat infections caused by MDR E. coli and K. pneumoniae. The present review discusses the efficacies of these therapies in mitigating these infections, which can be potentially used as an adjuvant therapy along with existing antibiotics.202335649163
486560.9975Molecular mechanisms related to colistin resistance in Enterobacteriaceae. Colistin is an effective antibiotic for treatment of most multidrug-resistant Gram-negative bacteria. It is used currently as a last-line drug for infections due to severe Gram-negative bacteria followed by an increase in resistance among Gram-negative bacteria. Colistin resistance is considered a serious problem, due to a lack of alternative antibiotics. Some bacteria, including Pseudomonas aeruginosa, Acinetobacter baumannii, Enterobacteriaceae members, such as Escherichia coli, Salmonella spp., and Klebsiella spp. have an acquired resistance against colistin. However, other bacteria, including Serratia spp., Proteus spp. and Burkholderia spp. are naturally resistant to this antibiotic. In addition, clinicians should be alert to the possibility of colistin resistance among multidrug-resistant bacteria and development through mutation or adaptation mechanisms. Rapidly emerging bacterial resistance has made it harder for us to rely completely on the discovery of new antibiotics; therefore, we need to have logical approaches to use old antibiotics, such as colistin. This review presents current knowledge about the different mechanisms of colistin resistance.201931190901
979670.9975Bacteriophage therapy to combat MDR non-fermenting Gram-negative bacteria causing nosocomial infections: recent progress and challenges. Clinicians face significant challenges in managing nosocomial infections, primarily due to antimicrobial resistance in multidrug-resistant bacteria. Regardless of the availability of a wide range of antimicrobials in the market, resistance is escalating rampantly with every passing day, which has become a global concern. Hence, it is essential to discover new and more efficient techniques to eliminate pathogens from healthcare settings. Along with eliminating pathogenic bacteria, mitigating their antimicrobial resistance with novel methods is very essential. Recently, bacteriophages have re-emerged as a promising therapeutic alternative to treat serious infections caused by bacterial pathogens. Bacteriophages were discovered for the first time a century ago, but their usage has recently regained more attention in treating bacterial pathogens. Bacteriophages also help in mitigating the worldwide problem of antibiotic resistance, particularly augmented by Gram-negative bacteria. This review discussed the advancements in the usage of bacteriophages in combating the antimicrobial resistance of multidrug-resistant Gram-negative bacteria, with a prime focus on Acinetobacter baumannii, Pseudomonas aeruginosa, and Burkholderia cepacia complex (Bcc), which are renowned non-fermenting Gram-negative bacteria (NFGNB) pathogens. Additionally, the effects of single phage, phage cocktails, and combination therapy with antibiotics on bacterial biofilms and polymicrobial biofilms are also discussed.202540478338
976680.9975Facile accelerated specific therapeutic (FAST) platform develops antisense therapies to counter multidrug-resistant bacteria. Multidrug-resistant (MDR) bacteria pose a grave concern to global health, which is perpetuated by a lack of new treatments and countermeasure platforms to combat outbreaks or antibiotic resistance. To address this, we have developed a Facile Accelerated Specific Therapeutic (FAST) platform that can develop effective peptide nucleic acid (PNA) therapies against MDR bacteria within a week. Our FAST platform uses a bioinformatics toolbox to design sequence-specific PNAs targeting non-traditional pathways/genes of bacteria, then performs in-situ synthesis, validation, and efficacy testing of selected PNAs. As a proof of concept, these PNAs were tested against five MDR clinical isolates: carbapenem-resistant Escherichia coli, extended-spectrum beta-lactamase Klebsiella pneumoniae, New Delhi Metallo-beta-lactamase-1 carrying Klebsiella pneumoniae, and MDR Salmonella enterica. PNAs showed significant growth inhibition for 82% of treatments, with nearly 18% of treatments leading to greater than 97% decrease. Further, these PNAs are capable of potentiating antibiotic activity in the clinical isolates despite presence of cognate resistance genes. Finally, the FAST platform offers a novel delivery approach to overcome limited transport of PNAs into mammalian cells by repurposing the bacterial Type III secretion system in conjunction with a kill switch that is effective at eliminating 99.6% of an intracellular Salmonella infection in human epithelial cells.202133712689
977490.9975A naturally inspired antibiotic to target multidrug-resistant pathogens. Gram-negative bacteria are responsible for an increasing number of deaths caused by antibiotic-resistant infections(1,2). The bacterial natural product colistin is considered the last line of defence against a number of Gram-negative pathogens. The recent global spread of the plasmid-borne mobilized colistin-resistance gene mcr-1 (phosphoethanolamine transferase) threatens the usefulness of colistin(3). Bacteria-derived antibiotics often appear in nature as collections of similar structures that are encoded by evolutionarily related biosynthetic gene clusters. This structural diversity is, at least in part, expected to be a response to the development of natural resistance, which often mechanistically mimics clinical resistance. Here we propose that a solution to mcr-1-mediated resistance might have evolved among naturally occurring colistin congeners. Bioinformatic analysis of sequenced bacterial genomes identified a biosynthetic gene cluster that was predicted to encode a structurally divergent colistin congener. Chemical synthesis of this structure produced macolacin, which is active against Gram-negative pathogens expressing mcr-1 and intrinsically resistant pathogens with chromosomally encoded phosphoethanolamine transferase genes. These Gram-negative bacteria include extensively drug-resistant Acinetobacter baumannii and intrinsically colistin-resistant Neisseria gonorrhoeae, which, owing to a lack of effective treatment options, are considered among the highest level threat pathogens(4). In a mouse neutropenic infection model, a biphenyl analogue of macolacin proved to be effective against extensively drug-resistant A. baumannii with colistin-resistance, thus providing a naturally inspired and easily produced therapeutic lead for overcoming colistin-resistant pathogens.202234987225
9445100.9974Bacteriophages of Mycobacterium tuberculosis, their diversity, and potential therapeutic uses: a review. Tuberculosis (TB) caused by Mycobacterium tuberculosis (M. tuberculosis) is a highly infectious disease and worldwide health problem. Based on the WHO TB report, 9 million active TB cases are emerging, leading to 2 million deaths each year. The recent emergence of multidrug-resistant tuberculosis (MDR-TB) and extensively drug-resistant tuberculosis (XDR-TB) strains emphasizes the necessity to improve novel therapeutic plans. Among the various developing antibacterial approaches, phage therapy is thought to be a precise hopeful resolution. Mycobacteriophages are viruses that infect bacteria such as Mycobacterium spp., containing the M. tuberculosis complex. Phages and phage-derived proteins can act as promising antimicrobial agents. Also, phage cocktails can broaden the spectrum of lysis activity against bacteria. Recent researches have also shown the effective combination of antibiotics and phages to defeat the infective bacteria. There are limitations and concerns about phage therapy. For example, human immune response to phage therapy, transferring antibiotic resistance genes, emerging resistance to phages, and safety issues. So, in the present study, we introduced mycobacteriophages, their use as therapeutic agents, and their advantages and limitations as therapeutic applications.202236550444
9802110.9974Transient comparison of techniques to counter multi-drug resistant bacteria: prime modules in curation of bacterial infections. Multidrug-resistant organisms are bacteria that are no longer controlled or killed by specific drugs. One of two methods causes bacteria multidrug resistance (MDR); first, these bacteria may disguise multiple cell genes coding for drug resistance to a single treatment on resistance (R) plasmids. Second, increased expression of genes coding for multidrug efflux pumps, which extrude many drugs, can cause MDR. Antibiotic resistance is a big issue since some bacteria may withstand almost all antibiotics. These bacteria can cause serious sickness, making them a public health threat. Methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococcus (VRE), Multidrug resistant Mycobacterium tuberculosis (TB), and CRE are gut bacteria that resist antibiotics. Antimicrobial resistance is rising worldwide, increasing clinical and community morbidity and mortality. Superbugs have made antibiotic resistance in some environmental niches even harder to control. This study introduces new medicinal plants, gene-editing methods, nanomaterials, and bacterial vaccines that will fight MDR bacteria in the future.202339816650
4866120.9974Resistance to polymyxins in Gram-negative organisms. Polymyxins have recently been re-introduced into the therapeutic arsenal to combat infections caused by multidrug-resistant Gram-negative bacteria. However, the emergence of strains resistant to these last-resort drugs is becoming a critical issue in a growing number of countries. Both intrinsic and transferable mechanisms of polymyxin resistance have been characterised. These mechanisms as well as the epidemiological data regarding four relevant bacterial pathogens (Escherichia coli, Klebsiella pneumoniae, Acinetobacter baumannii and Pseudomonas aeruginosa) are considered in this review. A special focus is made on plasmid-mediated resistance and the spread of mcr genes.201728163137
9806130.9974Resistance of Gram-Positive Bacteria to Current Antibacterial Agents and Overcoming Approaches. The discovery of antibiotics has created a turning point in medical interventions to pathogenic infections, but unfortunately, each discovery was consistently followed by the emergence of resistance. The rise of multidrug-resistant bacteria has generated a great challenge to treat infections caused by bacteria with the available antibiotics. Today, research is active in finding new treatments for multidrug-resistant pathogens. In a step to guide the efforts, the WHO has published a list of the most dangerous bacteria that are resistant to current treatments and requires the development of new antibiotics for combating the resistance. Among the list are various Gram-positive bacteria that are responsible for serious healthcare and community-associated infections. Methicillin-resistant Staphylococcus aureus, vancomycin-resistant Enterococcus faecium, and drug-resistant Streptococcus pneumoniae are of particular concern. The resistance of bacteria is an evolving phenomenon that arises from genetic mutations and/or acquired genomes. Thus, antimicrobial resistance demands continuous efforts to create strategies to combat this problem and optimize the use of antibiotics. This article aims to provide a review of the most critical resistant Gram-positive bacterial pathogens, their mechanisms of resistance, and the new treatments and approaches reported to circumvent this problem.202032586045
9446140.9974Newer antibiotics for the treatment of respiratory tract infections. PURPOSE OF REVIEW: In this review, we highlight some of the developments achieved over the past 2 years in the field of novel antimicrobial compounds. RECENT FINDINGS: Modification of existing compound classes to create more powerful compounds capable of overcoming pathogen resistance and the introduction of completely new classes of antibiotics and inhibitors of new bacterial targets or inhibitors of genes relating to virulence or pathogenesis are the strategies more commonly employed in pharmacologic research. Ketolides, oxazolidinones, streptogramins, glycylcyclines, and peptide deformylase inhibitors are among the most promising classes of antibiotics. Recently, several lines of research have documented that it is effective to target the infection process rather than killing bacteria. This is important because it is likely that such a therapeutic strategy could ablate infection without inducing resistance. SUMMARY: Emergence of resistance to the antibiotics currently employed in clinical practice is a continual stimulus for further research aimed at identifying novel antimicrobial compounds. These drugs will perhaps effectively fight against bacteria that now are scarcely controlled by the traditional antimicrobial agents. Health care personnel must appreciate that only judicious use of antimicrobial drugs will prevent the further uncontrolled spread of bacterial resistance. Implementation of reference guidelines would probably be an effective way to limit antibiotic misuse.200415071370
9808150.9974Understanding Recent Developments in Colistin Resistance: Mechanisms, Clinical Implications, and Future Perspectives. Colistin resistance, driven by chromosomal mutations and the spread of plasmid-mediated MCR genes, has emerged as a critical challenge in combating multidrug-resistant Gram-negative bacteria. This resistance compromises the efficacy of colistin, leading to higher treatment failure rates, prolonged hospitalizations, and increased mortality. Recent studies have highlighted key mechanisms, including lipid A modifications, that enable bacteria to evade colistin's effects. The global spread of MCR genes exacerbates the issue, underlining the need for improved diagnostics and rapid detection of resistant strains to prevent adverse patient outcomes. To combat this growing threat, a multifaceted approach is essential, involving enhanced antimicrobial stewardship, stricter infection control measures, and continued research into alternative therapies and diagnostic methods. Collaborative efforts from researchers, healthcare providers, policymakers, and the pharmaceutical industry are crucial to preserving colistin's effectiveness and mitigating the broader impact on public health.202541148650
9799160.9974Microbiology and drug resistance mechanisms of fully resistant pathogens. The acquisition of vancomycin resistance by Gram-positive bacteria and carbapenem resistance by Gram-negative bacteria has rendered some hospital-acquired pathogens impossible to treat. The resistance mechanisms employed are sophisticated and very difficult to overcome. Unless alternative treatment regimes are initiated soon, our inability to treat totally resistant bacteria will halt other developments in medicine. In the community, Gram-positive bacteria responsible for pneumonia could become totally resistant leading to increased mortality from this common infection, which would have a more immediate impact on our current lifestyles.200415451497
4852170.9974Recent trends in antibiotic resistance in European ICUs. PURPOSE OF REVIEW: Antimicrobial resistance is an emerging problem in ICUs worldwide. As numbers of published results from national/international surveillance studies rise rapidly, the amount of new information may be overwhelming. Therefore, we reviewed recent trends in antibiotic resistance in ICUs across Europe in the past 18 months. RECENT FINDINGS: In this period, infections caused by methicillin-resistant Staphylococcus aureus appeared to stabilize (and even decrease) in some countries, and infection rates due to Gram-positive bacteria resistant to vancomycin, linezolid or daptomycin have remained low. In contrast, we are witnessing a continent-wide emergence of infections caused by multiresistant Gram-negative bacteria, especially Escherichia coli and Klebsiella pneumoniae, with easily exchangeable resistance genes located on plasmids, producing enzymes such as extended spectrum β-lactamases and carbapenamases. In the absence of new antibiotics, prevention of infections, reducing unnecessary antibiotic use, optimizing adherence to universal hygienic and infection control measures, and improving implementation of diagnostic tests are our only tools to combat this threat. SUMMARY: As the epidemiology of antibiotic resistance in ICUs is rapidly changing toward more frequently occurring epidemics and endemicity of multi and panresistant Gram-negative pathogens, better infection control and improved diagnostics will become even more important than before.201121986462
9811180.9974"Infectious Supercarelessness" in Discussing Antibiotic-Resistant Bacteria. Many bacterial pathogens are exhibiting resistance to increasing numbers of antibiotics making it much more challenging to treat the infections caused by these microbes. In many reports in the media and perhaps even in discussions among physicians and biomedical scientists, these bacteria are frequently referred to as "bugs" with the prefix "super" appended. This terminology has a high potential to elicit unjustified inferences and fails to highlight the broader evolutionary context. Understanding the full range of biological and evolutionary factors that influence the spread and outcomes of infections is critical to formulating effective individual therapies and public health interventions. Therefore, more accurate terminology should be used to refer these multidrug-resistant bacteria.201628174759
9751190.9973Antibiotics-free compounds for managing carbapenem-resistant bacteria; a narrative review. Carbapenem-resistant (CR) Gram-negative bacteria have become a significant public health problem in the last decade. In recent years, the prevalence of CR bacteria has increased. The resistance to carbapenems could result from different mechanisms such as loss of porin, penicillin-binding protein alteration, carbapenemase, efflux pump, and biofilm community. Additionally, genetic variations like insertion, deletion, mutation, and post-transcriptional modification of corresponding coding genes could decrease the susceptibility of bacteria to carbapenems. In this regard, scientists are looking for new approaches to inhibit CR bacteria. Using bacteriophages, natural products, nanoparticles, disulfiram, N-acetylcysteine, and antimicrobial peptides showed promising inhibitory effects against CR bacteria. Additionally, the mentioned compounds could destroy the biofilm community of CR bacteria. Using them in combination with conventional antibiotics increases the efficacy of antibiotics, decreases their dosage and toxicity, and resensitizes CR bacteria to antibiotics. Therefore, in the present review article, we have discussed different aspects of non-antibiotic approaches for managing and inhibiting the CR bacteria and various methods and procedures used as an alternative for carbapenems against these bacteria.202439355778
