Unlabelled: The introduction of antibiotics in the beginning of the 20th century was one of the most important scientific breakthroughs in history. However, in recent decades, the growing threat of antimicrobial resistance (AMR) has shown the limitations of the current research and development programs for new antimicrobial drugs. In the last decade, 20 antibiotics, 7 β-lactam/β-lactamase inhibitor (BL/BLI) combinations and 4 non-traditional antibacterial drugs have been launched worldwide.
Methods: This study aimed to assess the time to patient access for new antibacterial drugs in countries in the European Union and the European Economic Area (EU/EEA). Time differences in marketing authorization from the U.S. Food and Drug Agency (FDA) and the European Medicines Agency (EMA) were also described, as well as the availability of each drug in the countries in the EU/EEA according to the national competent authorities.
Results: Substantial differences between countries were observed, with no or only one new drug available in some countries.
Conclusions: Improving pricing and reimbursement timelines and fostering collaboration between national health authorities and market authorization holders can enhance timely and equitable patient access to new antibacterial treatments in Europe. Equitable and sustainable access to antibacterial drugs is a cornerstone in the battle against AMR.

Drugs must accumulate at their target site to be effective, and inadequate uptake of drugs is a substantial barrier to the design of potent therapies. This is particularly true in the development of antibiotics, as bacteria possess numerous barriers to prevent chemical uptake. Designing compounds that circumvent bacterial barriers and accumulate to high levels in cells could dramatically improve the success rate of antibiotic candidates.

Background: Antimicrobial resistance poses a significant threat to global health, with its spread intricately linked across human, animal, and environmental sectors. Revealing the antimicrobial resistance gene (ARG) flow among the One Health sectors is essential for better control of antimicrobial resistance.
Results: In this study, we investigated regional ARG transmission among humans, food, and the environment in Dengfeng, Henan Province, China by combining large-scale metagenomic sequencing with culturing of resistant bacterial isolates in 592 samples.

Background: Antibiotic resistant bacteria are a threat to both human and animal health. Of special concern are resistance mechanisms that are transmissible between bacteria, such as extended-spectrum beta-lactamases (ESBL) and plasmid-mediated AmpC (pAmpC). ESBL/AmpC resistance is also of importance as it confers resistance to beta-lactam antibiotics including third generation cephalosporins.

Background: Bacterial vaginosis (BV) is a prevalent vaginal condition among reproductive-age women, characterized by off-white, thin vaginal discharge with a fishy odor. It increases susceptibility to sexually transmitted diseases (STDs) and pelvic inflammatory disease (PID). BV involves a shift in vaginal microbiota, with reduced lactobacilli and increased anaerobic bacteria.

Background: Successful treatment of pathogenic bacteria like Enterobacter Cloacae with bacteriophage (phage) counteract some hindrance such as phage stability and immunological clearance. Our research is focused on the encapsulation of phage HK6 within chitosan nanoparticles.
Result: Encapsulation significantly improves stability, efficacy, and delivery of phages.
