Emergence and Genomic Characterization of a Hypervirulent Klebsiella pneumoniae Isolate From a New Clone in Brazil

Microbiology and Immunology, EarlyView.
ABSTRACT Hypervirulent Klebsiella pneumoniae (hvKp) has emerged globally as a major public health concern, often associated with severe community‐acquired and healthcare‐associated human infections. Despite alerts from PAHO/WHO on convergent hvKp strains with multidrug resistance in Latin America, comprehensive data from Brazil, the region's largest ...

Altered Pathogen Spectrum of Spontaneous Bacterial Peritonitis in Patients Treated With Proton Pump Inhibitors

Alimentary Pharmacology &Therapeutics, EarlyView.
This multicenter, observational study reveals distinct alterations in the microbial spectrum of spontaneous bacterial peritonitis (SBP) associated with proton pump inhibitor use. These results are especially relevant for guiding empiric antibiotic therapy of SBP.

Targeting protein–protein interactions with reversible covalent modalities: Non‐cysteine chemistries

British Journal of Pharmacology, EarlyView.
Abstract Protein–protein interactions (PPIs) are central to diverse cellular functions, and represent a rapidly expanding class of therapeutic targets. Advancements in covalent drug design have enabled small‐molecule drugs to overcome challenges associated with engaging these targets, such as limited durations of action and difficult‐to‐drug (expansive,
