Effect of robA_Yp overexpression on the rate of Y. pestis killing by fluoroquinolones and aminoglycosides. Yp pGEM-Rob_Yp (overexpressing robA_Yp) and Yp pGEM-4Z (vector control) were treated with the indicated antibiotics at 5 × MIC₉₉. The means of triplicate treated cultures were plotted and standard error bars are shown.
