Dynamic processes of bacterial genome amplification involving a non-replicable but inheritable circular DNA molecule encoding multiple drug resistance proteins.
Hypervirulent Klebsiella pneumoniae (hvKp) is a significant cause of severe community-acquired infection, primarily in Asia. Here, the authors characterise the genetic profile, phylogenetic structure, and plasmid features of hvKp in Vietnam.
Tuberculosis is a major global health threat. Here, the authors develop a single-cell drug discovery approach and identify a compound that tunes bacterial phenotypic variation. This enhances the activity of anti-tubercular drugs against the pathogen.
This study on how Staphylococcus aureus manipulates host-derived fatty acids reveals that a bacteriallipase (Lip2) converts toxic fatty acids and cholesterol into innocuous cholesteryl esters.
We characterize the activity of fluorofolin, a potent inhibitor of dihydrofolate reductase, against Pseudomonas aeruginosa. By exploiting a divergence in thymidine metabolism, fluorofolin becomes selective for P. aeruginosa in the presence of thymine, demonstrating that it can be a narrow-spectrum antibiotic for this bacterial pathogen.
We found trade-offs among the environmental and animal welfare impacts of pig farms — those that had low greenhouse gas emissions typically had low land use but poor animal welfare and high antimicrobial use. Some farms performed well in all four impacts, but these farms were not consistently associated with any particular farm or label type.
Researchers developed an AI model that designs novel, synthesizable antibiotic compounds — several of which showed potent in vitro activity against priority pathogens.
In this study, Liu et al. explore the interplay between a fungal effector and a plant cysteine protease and design a small-molecule compound aimed at targeting this effector to combat rice blast disease.
