Special Issue Information

Dear Colleagues,

The mucosal surfaces of the body contain a diverse range of microbes which help to form a protective microbiome. This microbiome can be disrupted by the use of antibiotics, among other factors. This disruption can lead to overgrowth of the mucosal surface by potential pathogens and the development of inflammation and infection. These potential pathogens can also be resistant to antibiotics, and so their elimination and re-establishment of the normal microbiome can be difficult. Additionally, if the mucosal surfaces are damaged, this can present new surfaces for potential pathogens to colonize, even without any disruption to the normal microbiome. The use of medical devices such as contact lenses, hearing aids, catheters and sanitary devices may also present new surfaces that can be colonized by potential pathogens.

This Special Issue seeks papers on the non-gastrointestinal-tract mucosal surfaces of humans—that is the eyes, ears, respiratory tract and urogenital systems. Papers on the normal microbiome of these mucosal surfaces and the consequences of antimicrobials (antibiotics, disinfectants, phages etc.) and medical devices on the normal microbiome of these mucosal surfaces are welcome. We also encourage the submission of papers describing the development of new therapeutics to prevent or treat diseases of these systems, as well as clinical trials, observational studies, case series reports, laboratory studies, systematic reviews and meta-analyses that provide new insights into these systems. Data on the effects of antimicrobial resistance on clinical outcomes are also encouraged

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 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 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. Antibiotics 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 2900 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.

Abstract
The global rise in antibiotic resistance in bacteria poses a major challenge in treating infectious diseases. Polymyxins (e.g., polymyxin B and colistin) are last-resort antibiotics against resistant Gram-negative bacteria, but the effectiveness of polymyxins is decreasing due to widespread resistance among clinical isolates.

The global rise in antibiotic resistance in bacteria poses a major challenge in treating infectious diseases. Polymyxins (e.g., polymyxin B and colistin) are last-resort antibiotics against resistant Gram-negative bacteria, but the effectiveness of polymyxins is decreasing due to widespread resistance among clinical isolates. The aim of this literature review was to decipher the evolving mechanisms of resistance to polymyxins among pathogens of clinical significance. We deciphered the molecular determinants of polymyxin resistance, including distinct intrinsic molecular pathways of resistance as well as evolutionary characteristics of mobile colistin resistance. Among clinical isolates, Acinetobacter stains represent a diversified evolution of resistance, with distinct molecular mechanisms of intrinsic resistance including naxD, lpxACD, and stkR gene deletion. On the other hand, Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa are usually resistant via the PhoP-PhoQ and PmrA-PmrB pathways. Molecular evolutionary analysis of mcr genes was undertaken to show relative relatedness across the ten main lineages. Understanding the molecular determinants of resistance to polymyxins may help develop suitable and effective methods for detecting polymyxin resistance determinants and the development of novel antimicrobial molecules.
