Special Issue Information
Dear Colleagues,
Infections due to multi-drug-resistant (MDR), extensively drug-resistant (XDR) and pan-drug-resistant (PDR) Gram-negatives are increasing worldwide, forcing clinicians to use last-resort antimicrobials for their management. These salvage treatment options include the few new antibacterials developed recently (cefiderocol, ceftolozane-tazobactam meropenem-vaborbactam, imipenem-relebactam, ceftazidime- and aztreonam-avibactam, cefepime-taniborbactam, eravacycline and omadacycline) and older antibacterials, like polymyxins and tigecycline. Unfortunately, resistance to last-resort agents is also reported, putting in danger their use and making infections due to these pathogens practically untreatable.
The scope of this Special Issue is to update knowledge on resistance of Gram-negative pathogens to last-resort antimicrobials through manuscripts highlighting their epidemiology, resistance mechanisms and genomics, but also manuscripts addressing alternative treatment options or reversal of resistance methods, like combination therapy, phage therapy, antimicrobial peptides, CRISPR-cas system and PK/PD studies. Finally, manuscripts describing new microbiological tools for resistance detection are also welcome.

Manuscript Submission Information
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. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Microorganisms is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
