MetabolomicsDivergent relationships between faecal microbiota and metabolome following distinct antibiotic-induced disruptions
The intestinal microbiome plays an essential role in regulating many aspects of host physiology, and its disruption through antibiotic exposure has been implicated in the development of a range of serious pathologies. The complex metabolic relationships that exist between members of the intestinal m...

MetabolomicsSubcellular antibiotic visualization reveals a dynamic drug reservoir in infected macrophages
Tuberculosis, caused by the intracellular pathogen Mycobacterium tuberculosis, remains the world's deadliest infectious disease. Sterilizing chemotherapy requires at least 6 months of multidrug therapy. Difficulty visualizing the subcellular localization of antibiotics in infected host cells means t...

MetabolomicsOriginal data of bacterial antibiotic resistance lipidomics
Plasmid-mediated dissemination of mcr genes has severely compromised colistin efficacy, necessitating adjuvants that restore antibacterial potency without exacerbating toxicity. Despite their essential roles in bacterial survival and virulence, metal ion acquisition systems remain underexplored as t...

MetabolomicsUntargeted Metabolomics To Ascertain Antibiotic Modes of Action
Deciphering the mode of action (MOA) of new antibiotics discovered through phenotypic screening is of increasing importance. Metabolomics offers a potentially rapid and cost-effective means of identifying modes of action of drugs whose effects are mediated through changes in metabolism. Metabolomics...

MetabolomicsMacrophage-mediated antibiotic evasion and competitive dominance of mcr-3-carrying Escherichia coli

Mobile colistin resistance (mcr) genes undermine the efficacy of last-line polymyxin antibiotics, and the global prevalence of mcr-3 continues to rise despite reduced colistin use. Here, we show that mcr-3-positive Escherichia coli (E. coli) confers a survival advantage by reprogramming macrophag...

MetabolomicsGut Microbiome and Metabolome Alterations in Mice with Arsenic Exposure and Antibiotic Treatment: Potential Role of Arsenic Biotransformation Genes

Arsenic is the most prevalent toxic metalloid in environment. Evidence of mouse models (germ-free or antibiotic treatment) indicates the gut microbiota’s involvement in the metabolism of ingested arsenic. Linking genes to gut microbial arsenic metabolism with altered toxicity and lifetime in the ...

MetabolomicsUntargeted serum metabolomics of early-life antibiotic intervention, fecal microbiota transplantation restoration, and short-term high-fat diet effects in C57BL/6 mice
This study profiles the serum metabolome in C57BL/6 mice subjected to early-life antibiotic treatment (vancomycin and gentamicin, 2 weeks), followed by fecal microbiota transplantation and a short-term high-fat diet. Serum samples were collected longitudinally and analyzed by liquid chromatography-t...

MetabolomicsClostridium butyricum MIYAIRI 588-induced protectin D1 has an anti-inflammatory effect on antibiotic-induced intestinal disorder
Metabolites are thought as the end products in cellular regulatory processes and their levels show the strongest relationships with the phenotype. Previously, we showed that the administration of Clostridium butyricum MIYAIRI 588 (CBM 588) upregulated protectin D1, an anti-inflammatory lipid metabol...

MetabolomicsTargeted bile acid profiling of Faecalibaculum rodentium-induced bile acid remodeling in antibiotic-treated mice
This study investigated whether Faecalibaculum rodentium remodels the intestinal bile acid pool through bacterial bile salt hydrolase activity in antibiotic-treated male C57BL/6J mice. Mice were assigned to three groups: control, Faecalibaculum rodentium gavage, and Faecalibaculum rodentium gavage c...

MetabolomicsStress-induced enrichment of Pseudomonas sp. stimulates the adaptive response of Auxenochlorella pyrenoidosa and antibiotic-resistant proliferation

The phycosphere is an important ecological niche for bacteria and antibiotic resistance genes (ARGs). However, whether and how the interaction between microalgae and bacteria changed, and its further effect on the transmission of ARGs under pollutant stress remains enigmatic. Here, Auxenochlorell...
