Fitness effects of antimicrobial resistance genes in changing environments

Alberto Hipólito, Lucía García-Pastor, Alexandra von Strempel, Anna S. Weiß, Jorge Sastre-Domínguez, Ester Vergara, Julio Álvarez, Ayari Fuentes-Hernández, Rafael Peña‐Miller, Álvaro San Millán, Bärbel Stecher, José Antonio Escudero

This study measures the fitness effects of 136 antimicrobial resistance genes in changing environments and finds that oxygen availability modulates their cost.

Stress-Induced Cooperation Promotes Tolerance in Resource-Limited Auxotrophic Microbial Consortia

Daniela Reyes-González, Haydee De Luna-Valenciano, Fernando Santos-Escobar, María Rebolleda‐Gómez, Rafael Peña‐Miller, Ayari Fuentes-Hernández

The paper shows that chloramphenicol promotes cooperation in auxotrophic E. coli consortia by increasing ppGpp and shifting proteome allocation toward amino acid biosynthesis and export, enhancing cross-feeding and tolerance.
