MetabolomicsAntimicrobial Efficacy of Bifidobacterium longum FB1-4 Cell-Free Supernatant Against MRSA: Insights into Mechanisms and Food Matrix Application

The food safety landscape faces a significant challenge from methicillin-resistant Staphylococcus aureus (MRSA), a virulent and antibiotic-resistant foodborne pathogen. This study investigates the antimicrobial properties and mechanisms of cell-free supernatant (CFS) from Bifidobacterium longum F...

MetabolomicsCell Membrane Remodeling Mediates Polymyxin B Resistance in Klebsiella pneumoniae: An Integrated Proteomics and Metabolomics Study
Polymyxin B (PB) is introduced into the clinic as the last-line therapy against carbapenem-resistant Klebsiella pneumoniae (CRKP). Unfortunately, increased resistance to PB in Klebsiella pneumoniae (K. pneumoniae) has threatened global health. Resistance of K. pneumoniae ...

MetabolomicsA synthetic antibiotic class with a deeply-optimized design for overcoming bacterial resistance

The lack of new drugs that are effective against antibiotic-resistant bacteria has caused increasing concern in global public health. Based on this study, we report development of a modified antimicrobial drug through structure-based drug design (SBDD) and modular synthesis. The optimal modified ...

MetabolomicsDysregulation of Streptococcus pneumoniae zinc homeostasis breaks ampicillin resistance in a pneumonia infection model

Streptococcus pneumoniae is the primary cause of community-acquired bacterial pneumonia with rates of penicillin and multi-drug resistance exceeding 80% and 40%, respectively. The innate immune response generates a variety of antimicrobial agents to control infection including zinc stres...

MetabolomicsLactate-driven lysine lactylation mediates high-level colistin resistance in Salmonella
Intracellular pathogens are particularly refractory to antibiotic eradication, leading to persistent and relapsing infections. However, how intracellular metabolic microenvironments shape antibiotic resistance phenotypes remains poorly understood. Here we delineate a metabolic-regulatory axis wherei...

TranscriptomicsThe antimicrobial peptide-sensing system aps of Staphylococcus aureus
Staphylococcus aureus is a leading cause of hospital-associated infections. In addition, highly virulent strains of methicillin-resistant S. aureus (MRSA) are currently spreading outside health care settings. Survival in the human host is largely defined by the ability of S. aureus to resist mechani...

MetabolomicsCyromazine accelerates the dissemination of antibiotic resistance genes by promoting the conjugative transfer of the SXT integrative conjugative element

Antimicrobial resistance (AMR) is one of the most urgent challenges in public health, and the horizontal transfer of antibiotic resistance genes (ARGs) mediated by mobile genetic elements (MGEs) drives its widespread global dissemination. Although integrative conjugative elements (ICEs) outnumber...

MetabolomicsMetabolomics analysis identifies metabolites associated with systemic acquired resistance in Arabidopsis

BACKGROUND: Systemic acquired resistance (SAR) is a plant defense response that provides long-lasting, broad-spectrum pathogen resistance to uninfected distal leaves following an initial localized infection. However, little information is available on the molecular biological bas...
