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...

MetabolomicsLeucine degradation metabolite ratio as a measure of meropenem susceptibility in carbapenem-resistant Klebsiella pneumoniae

Rapid detection of carbapenem-resistant Klebsiella pneumoniae (CRKP) is essential for effective clinical management and surveillance. This study investigated volatile organic compounds (VOCs) as phenotypic biomarkers of carbapenem resistance, with the goal of developing a translationally...

MetabolomicsGenome-wide mapping of genetic suppression events in Streptococcus pneumoniae
Historically, suppressor analysis has been a powerful tool for uncovering the functions of essential genes. In this study, we report Sup-seq, a transposon-sequencing technique with random DNA barcodes that enables genome-wide detection of genetic suppression. When applied to seven essential genes in...

MetabolomicsAirway metabolic profiling during Streptococcus pneumoniae infection identifies branched chain amino acids as signatures of upper airway colonisation

Streptococcus pneumoniae is a leading cause of community-acquired pneumonia and bacteraemia and is capable of remarkable phenotypic plasticity, responding rapidly to environmental change. Pneumococcus is a nasopharyngeal commensal, but is responsible for severe, acute infections followin...

MetabolomicsIdentification of BolA protein reveals a novel virulence factor in Klebsiella pneumoniae that contributes to liver abscess in mice

BolA has been characterized as an important transcriptional regulator, which is induced in the stationary phase of growth and is often associated with bacterial virulence. This study was initiated to elucidate the role of the BolA in the virulence of K. pneumoniae. Using a mous...

MetabolomicsWhole genome sequencing and targeted metabolomics of multidrug-resistant Klebsiella pneumoniae KP21-10C
This study investigates multidrug-resistant Klebsiella pneumoniae KP21-10C using whole genome sequencing and targeted energy metabolomics. Genomic sequencing data were generated to characterize the bacterial genome, and targeted LC-MS/MS metabolomics was performed to quantify energy metabolism-relat...

MetabolomicsMulti-0mics and Machine Learning-Based Profiling of Severity signatures in Mycoplasma Pneumoniae Infection in children

Mycoplasma pneumoniae pneumonia (MPP) is a common respiratory infection in children. Yet the mechanisms driving its progression to severe disease remain poorly understood. This study employs a comprehensive proteomic and metabolomic approach to elucidate severity-related pathways and identify pot...
