Cryptic β-lactamase evolution is driven by low β-lactam concentrations

C. Frohlich, J. A. Gama, K. Harms, V. H. A. Hirvonen, B. A. Lund, M. W. van der Kamp, P. J. Johnsen, O. Samuelsen, H.-K. S. Leiros

The paper shows that low β-lactam concentrations drive cryptic evolution of β-lactamases through fitness benefits in competition experiments, not increased resistance.

Piggybacking on niche-adaptation reduces the cost of multidrug resistance plasmids

J. Kloos, J. A. Gama, J. Hegstad, O. Samuelsen, P. J. Johnsen

The paper shows that chromosomal mutations in E. coli reduce the cost of multidrug resistance plasmids by downregulating plasmid gene expression during niche adaptation.
