Beta-lactamase dependent and independent evolutionary paths to high-level ampicillin resistance [PDF]
The incidence of beta-lactam resistance among clinical isolates is a major health concern. A key method to study the emergence of antibiotic resistance is adaptive laboratory evolution. However, in the case of the beta-lactam ampicillin, bacteria evolved

Basal level of ppGpp coordinates Escherichia coli cell heterogeneity and ampicillin resistance and persistence [PDF]
The universal stringent response alarmone ppGpp (guanosine penta and tetra phosphates) plays a crucial role in various aspects of fundamental cell physiology (e.g., cell growth rate, cell size) and thus bacterial tolerance to and survival of external ...
