| Open AccessMutations in the efflux pump regulator MexZ shift tissue colonization by Pseudomonas aeruginosa to a state of antibiotic tolerance
Mutations in mexZ, encoding a negative regulator of efflux pump genes, are frequently acquired by Pseudomonas aeruginosa during early lung infection, but do not confer high antibiotic resistance as measured in lab tests. Here, Laborda et al. show that mexZ mutations affect quorum sensing pathways, thus promoting tissue invasiveness and protecting bacteria from the action of antibiotics within tissues.
