The analysis of the role of MexAB-OprM on quorum sensing homeostasis shows that the apparent redundancy of Pseudomonas aeruginosa multidrug efflux pumps allows keeping the robustness and the plasticity of this intercellular signaling network

M. Alcalde-Rico, J. Olivares-Pacheco, N. M. Halliday, M. Camara, J. L. Martinez

This study shows that overexpression of MexAB-OprM in Pseudomonas aeruginosa impairs quorum sensing by reducing intracellular octanoate, not by extruding the QS signal, highlighting the distinct mechanisms of efflux pump redundancy.

High prevalence of class 1 integrase and characterization of class 1 integron gene cassettes in multiresistant bacteria isolated from the gut microbiota of extended antibiotic treated Salmo salar fish farms

F. Vasquez Ponce, S. Higuera Llanten, J. Cortes Salinas, N. Zimin Veselkoff, S. H. Marshall Gonzalez, F. O. Mardones, J. Olivares-Pacheco

The paper identifies class 1 integrase in multiresistant bacteria from antibiotic-treated salmon farms and characterizes integron gene cassettes, linking them to anthropogenic sources.
