Ethidium bromide MIC screening for enhanced efflux pump gene expression or efflux activity in Staphylococcus aureus. Antimicrob Agents Chemother 2010;54

by Diixa Patel, Christos Kosmidis, Susan M. Seo, Glenn W. Kaatz
"... Multidrug resistance efflux pumps contribute to antimicrobial and biocide resistance in Staphylococcus aureus. The detection of strains capable of efflux is time-consuming and labor-intensive using currently available techniques. A simple and inexpensive method to identify such strains is needed. Et ..."

-PCR identified the increased expression of one or more MDR efflux pump genes in 151/309 clinical strains (49%). Ethidium bromide MIC testing was insensitive (48%) but specific (92%) in identifying strains with gene overexpression, but it was highly sensitive (95%) and specific (99%) in identifying strains

Dueling Regulatory Properties of a Transcriptional Activator (MtrA) and Repressor (MtrR) That Control Efflux Pump Gene Expression in

by Neisseria Gonorrhoeae, Yaramah M. Zalucki, A Vijaya Dhulipala, William M. Shafera
"... ABSTRACT MtrA is a member of the AraC family of transcriptional regulators and has been shown to play an important role in enhancing transcription of themtrCDE operon, which encodes a tripartite multidrug efflux pump, when gonococci are exposed to a sublethal level of antimicrobials. Heretofore, the ..."

by Multidrug Resistance, Michelle C. Swick, Sonia K. Morgan-linnell, Kimberly M. Carlson, Lynn Zechiedrich , 2010
"... In a single quantitative study, we measured acrA, acrB, tolC, mdfA, and norE expression in Escherichia coli clinical isolates by using real-time PCR. acrA and acrB overexpression strongly correlated with fluoroquinolone and multidrug resistance; tolC, mdfA, and norE expression did not. The order of ..."

of abundance of efflux pump transcripts in all fluoroquinolone-susceptible isolates was tolC (highest), then acrA and acrB, and then mdfA and norE. Our findings suggest acrAB overexpression is an indicator of multidrug resistance. Multidrug resistance (MDR) is an increasing public health concern worldwide (7
