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...

MetabolomicsHolistic Characterization of a Salmonella Typhimurium Infection Model Using Integrated Molecular Imaging

A more complete and holistic view on host–microbe interactions is needed to understand the physiological and cellular barriers that affect the efficacy of drug treatments and allow the discovery and development of new therapeutics. Here, we developed a multimodal imaging approach combining histop...

MetabolomicsAlterations in the gut microbiota and metabolic profiles coincide with intestinal damage in mice with a bloodborne Candida albicans infection
Candida albicans is an opportunistic fungus that can threaten life especially in patients with candidemia. The morbidity and mortality of candidemia originating from a central venous catheter (CVC) and illicit intravenous drug use (IVDU) are increasing. However, the mechanism underlying the bloodbor...

MetabolomicsOverexpression of tlr5 adrffects gut microbiota resistance to Salmonella infection

BACKGROUND: The gut microbiome and the host immune system interact synergistically to maintain intestinal health and defend against infections. Toll-like receptor 5 (TLR5), known for recognizing bacterial flagellin, plays a pivotal role in this regulatory network. Despite significant advances in ...

MetabolomicsHarnessing microbial-derived metabolites in the urinary tract to prevent infection induced catheter encrustation

Proteus mirabilis is a predominant cause of catheter associated urinary tract infection (CAUTI), and a key virulence factor is its urease enzyme which hydrolyzes urea to ammonia. This process results in the formation of urinary stones, facilitating catheter blockage and bacteremia. The o...

MetabolomicsIn plaque-mass spectrometry imaging of a bloom-forming alga during viral infection reveals a metabolic shift towards odd-chain fatty acid lipids (GC- and LC-MS assays)

Tapping into the metabolic cross-talk between a host and its virus can reveal unique strategies employed during infection. Viral infection is a dynamic process that generates an evolving metabolic landscape. Gaining a continuous view into the infection process is highly challenging and is limited...

MetabolomicsLipid mediators of inflammation in BALF 3-11 days after infection with influenza
Bioactive lipid mediators play a crucial role in the induction and resolution of inflammation. To elucidate their involvement during influenza infection, liquid chromatography/mass spectrometry lipidomic profiling of 141 lipid species was performed on a mouse influenza model using two viruses of sig...

MetabolomicsElevated CO2 and virus infection impacts wheat and aphid metabolism

INTRODUCTION: The aphid Rhopalosiphum padi L. is a vector of Barley yellow dwarf virus (BYDV) in wheat and other economically important cereal crops. Increased atmospheric CO2 has been shown to alter plant growth and metabolism, enhancing BYDV disease in wheat. However, the bioch...

MetabolomicsSerine Metabolism Tunes Immune Responses To Promote Oreochromis niloticus Survival upon Edwardsiella tarda Infection
Overactive immune response is a critical factor triggering host death upon bacterial infection. However, the mechanism behind the regulation of excessive immune responses is still largely unknown, and the corresponding control and preventive measures are also to be explored. In this study, we find t...

MetabolomicsDifferential role of sphingomyelin in influenza virus, rhinovirus and SARS-CoV-2 infection of Calu-3 cells
Host cell lipids play a pivotal role in the pathogenesis of respiratory virus infection. However, a direct comparison of the lipidomic profile of influenza virus and rhinovirus infections is lacking. In this study, we first compared the lipid profile of influenza virus and rhinovirus infection in a ...
