The Antimicrobial Gut Resistome of the Wayampi reveals a shared background of antibiotic and metal resistance genes with industrialised populations, underscoring the robust-yet-fragile architecture of human gut microbiomes.

Miguel D. Fernández-de-Bobadilla, Ana Elena Pérez‐Cobas, Antoine Andremont…·Teresa M. Coque

The study analyzes the gut resistome of the Wayampi, revealing similar antibiotic resistance gene richness to Europeans but higher metal resistance gene diversity, highlighting shared and distinct resistance patterns.

A new type of AmpC β-lactamases defined by PIB-1, a metal-dependent carbapenem-hydrolyzing β-lactamase, from Pseudomonas aeruginosa: structural and functional analysis.

Francisco J. Medrano, Sara Hernando‐Amado, José Luis Martínez, Antonio Romero

The paper identifies PIB-1, a metal-dependent carbapenem-hydrolyzing β-lactamase from Pseudomonas aeruginosa, structurally and functionally distinct from typical AmpC β-lactamases.

Efflux pump mutations in Pseudomonas aeruginosa cause low-level clinical resistance and high-level tolerance to antibiotics in patients

Pablo Laborda, Signe Lolle, Sara Hernando‐Amado…·Helle Krogh Johansen

This study shows that mexZ mutations in Pseudomonas aeruginosa lead to antibiotic tolerance and altered colonization in human airway models through overexpression of lecA.
