A BBC investigation finds kits on sale containing more than 500 times the legal limit of bleach.

mRNA vaccines targeting SARS-CoV-2 also sensitize tumours to immune checkpoint inhibitors.

Despite being a virulence factor, candidalysin toxin is essential for Candida albicans to penetrate the oral epithelium to establish and maintain non-infectious colonization

Abstract. The increasing interest in finding new viruses within (meta)genomic datasets has fueled the development of computational tools for virus detectio

Microbial growth is extremely slow within the first 30 days of thaw. Temperature may drive which taxa are active, but not growth rates Subsurface microbes preferentially produce glycolipids over ...

The antibiotic polymyxin B requires bacterial metabolic activity to cause sufficient damage to the outer membrane to access the inner membrane, which it permeabilizes via an energy-independent mechanism to kill the cell.

Metagenomic investigation of archaeological dental calculus has provided insights into the changing oral health, disease, and diet of past human societies, but little is known about the oral microbiot...

Molecular testing has greatly improved how viruses are diagnosed; however, gaps remain, including limited sensitivity directly from specimens and inability to differentiate active from resolved infection. In this study, we investigated the use of a distinct diagnostic approach, mass spectrometry for detection of metabolites (small molecules) combined with machine learning analysis, for the diagnosis of SARS-CoV-2 and other respiratory viruses. We demonstrated strong performance of this approach directly from upper respiratory swab samples to differentiate SARS-CoV-2-infected versus uninfected individuals. Extension of this approach to influenza and RSV maintained a high level of performance. This research suggests that mass spectrometry-based infectious disease diagnostic testing has clinical potential and that these metabolomic features may reveal novel host-pathogen interactions and therapeutic targets. Applying a similar approach to prospective, multisite cohorts of patients with other infectious diseases carries potential to extend our understanding of the metabolic pathways involved in the host response to infection.

Uridine boosts aminoglycoside treatment efficiency against antibiotic-susceptible as well as antibiotic-resistant E. coli strains.

Yang et al. identify the oral commensal Veillonella as a key driver of Clostridioides difficile infection in Crohn’s disease. Veillonella promotes pathogen germination by disrupting bile acid recyclin...
