Multi-drug resistance of pathogenic bacterial clinical isolates is now known to be mainly due to over-expressed efflux pumps that result from therapy with antibiotics that is either ineffective or improperly administered . The development of the MDR phenotype is thus problematic to therapy since resistance to the antibiotic initially used also bestows resistance to antibiotics of the same class and or other classes of antibiotics [1,2]. For the past two decades, much has been learned about the regulation and control of efflux pumps that render the clinical isolate with an MDR phenotype. Nevertheless, at this time, although many compounds have been identified to affect the activity of the over-expressed efflux pump of a given MDR bacterium and therefore render the antibiotic bacterium susceptible to antibiotics to which it was initially resistant, none have yet to reach the market as adjuncts to antibiotic therapy. The special issue of “Antibiotics” "Efflux pumps of multi-drug resistant pathogenic bacteria: Their genetic regulation, molecular biology and possible control with newly designed agents." will receive contributions from experts in the field of efflux pumps, their regulation and potential control with newly discovered agents from natural and chemically derived sources. We hope that those who are conducting research in this area will also submit their contributions for publication in this special issue.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are refereed through a peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Antibiotics is an international peer-reviewed Open Access quarterly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. For the first couple of issues the Article Processing Charge (APC) will be waived for well-prepared manuscripts. English correction and/or formatting fees of 250 CHF (Swiss Francs) will be charged in certain cases for those articles accepted for publication that require extensive additional formatting and/or English corrections.
