A real-time analysis of QacR-regulated multidrug resistance in Staphylococcus aureus.

Here we describe the construction and characterization of a biosensing reporter where luxCDABE genes from Photorhabdus luminescens, engineered for expression in Gram-positive organisms, are under the transcriptional control of QacR repressor from Staphylococcus aureus. In non-pathogenic S. aureus model system we analyzed the activity of the regulatory… CONTINUE READING
