| 9174 | 7 | 0.9974 | Developing Phage Therapy That Overcomes the Evolution of Bacterial Resistance. The global rise of antibiotic resistance in bacterial pathogens and the waning efficacy of antibiotics urge consideration of alternative antimicrobial strategies. Phage therapy is a classic approach where bacteriophages (bacteria-specific viruses) are used against bacterial infections, with many recent successes in personalized medicine treatment of intractable infections. However, a perpetual challenge for developing generalized phage therapy is the expectation that viruses will exert selection for target bacteria to deploy defenses against virus attack, causing evolution of phage resistance during patient treatment. Here we review the two main complementary strategies for mitigating bacterial resistance in phage therapy: minimizing the ability for bacterial populations to evolve phage resistance and driving (steering) evolution of phage-resistant bacteria toward clinically favorable outcomes. We discuss future research directions that might further address the phage-resistance problem, to foster widespread development and deployment of therapeutic phage strategies that outsmart evolved bacterial resistance in clinical settings. | 2023 | 37268007 |

| 9811 | 15 | 0.9973 | "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. | 2016 | 28174759 |
| 8168 | 16 | 0.9973 | Understanding antimicrobial resistance (AMR) mechanisms and advancements in AMR diagnostics. The overuse and abuse of antibiotics, which results in the evolution of resistant microorganisms, is the primary cause of the global health catastrophe known as antimicrobial resistance (AMR). The enzymatic breakdown of antibiotics, target site modification, efflux pump overexpression, and the formation of biofilm are some of the mechanisms responsible for acquiring antimicrobial resistance (AMR). These mechanisms enable bacteria to evade or neutralize the effects of antimicrobial agents, complicating treatment options and increasing mortality rates. The rapid dissemination of resistance genes via horizontal gene transfer further exacerbates the problem, necessitating urgent intervention. Advanced AMR diagnostics are transforming the fight against antimicrobial resistance. Biosensors enable rapid, point-of-care detection; Cluster regularly interspaced short palindromic repeat (CRISPR) technologies offer precise identification of resistance genes; and mass spectrometry provides fast, accurate profiling. Automated systems streamline workflows and boost throughput, while flow cytometry delivers real-time, single-cell analysis of phenotypic resistance. Together, these innovations accelerate detection and support targeted antimicrobial stewardship, essential for combating the global AMR threat. This review covers the mechanisms underlying antimicrobial resistance (AMR) and recent advancements in AMR diagnostic technologies. | 2025 | 40544537 |
| 9445 | 17 | 0.9972 | Bacteriophages of Mycobacterium tuberculosis, their diversity, and potential therapeutic uses: a review.

| 9752 | 18 | 0.9972 | Engineered 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.

| 9446 | 19 | 0.9972 | Newer 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. | 2004 | 15071370 |
