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...

MetabolomicsOrganic Acids Modulate Systemic Metabolic Perturbation Caused by Salmonella Pullorum Challenge in Early-Stage Broilers
The objectives of this study were to determine the protective effects of organic acids (OA) in broilers exposed to Salmonella Pullorum challenge at early stage and to explore the potential benefits of OA by metabolomics analysis. The treatment groups included non-challenged, S. Pullorum-challenged, ...

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...

ProteomicsPredictive Signatures of 19 Antibiotic-Induced Escherichia coli Proteomes
Identifying the mode of action (MOA) of antibacterial compounds is the fundamental basis for the development of new antibiotics, and the challenge increases with the emerging secondary and indirect effect from antibiotic stress. Although various omics-based system biology approaches are currently av...

MetabolomicsMetabolomics analysis reveals the participation of efflux pumps and ornithine in the response of Pseudomonas putida DOT-T1E cells to challenge with propranolol
Efflux pumps are critically important membrane components that play a crucial role in strain tolerance in Pseudomonas putida to antibiotics and aromatic hydrocarbons that result in these toxicants being expelled from the bacteria. Here, the effect of propranolol on P. putida was examined by sudden a...

MetabolomicsGlutamate-mediated metabolic rewiring boosts CpxA/R-OmpF porin and proton motive force to resensitize antibiotic-resistant Escherichia coli to ceftazidime

Ceftazidime (CAZ) is a critically important broad-spectrum antibiotic widely used in clinical practice. However, the rapid emergence of bacterial resistance to CAZ poses a significant challenge in treating infections caused by multidrug-resistant pathogens. In this study, we employed a metabolism...

TranscriptomicsEscherichia coli global gene expression due ciprofloxacin challenge in human whole blood
Treatment failures of antibiotic therapy are of major concern and can be caused by a misalignment of the antibiotic susceptibility determined in vitro with the behaviour of the pathogen in the patient. The aim of this study was to investigate the transcriptomic response of the uropathogenic strain E...

TranscriptomicsGAF competence
We applied a novel negative selection strategy called genomic array footprinting (GAF) to identify genes required for genetic transformation of the gram-positive bacterium Streptococcus pneumoniae. Genome-wide mariner-transposon mutant libraries in S. pneumoniae strain R6 were challenged by transfor...

TranscriptomicsRNA-Seq of human bronchoalveolar lavage and lung biopsy samples in the segmental endotoxin challenge model
Segmental instillation of lipopolysaccharide (LPS) by bronchoscopy can be used as a model to safely induce transient airway inflammation in the human lung. The LPS challenge model enables investigation of cellular mechanisms involved in pulmonary inflammatory processes as well as pharmacodynamic ana...
