Special Issue Information
Dear Colleagues,
Antibiotic resistance in Gram-negative bacteria poses a significant challenge in clinical settings, leading to increasing morbidity, mortality, and healthcare costs worldwide. These pathogens, notorious for their robust defense mechanisms and ability to rapidly disseminate resistance genes, are at the forefront of the antibiotic resistance crisis. This Special Issue aims to focus on unravelling the complex molecular mechanisms underlying antibiotic resistance in Gram-negative bacteria, offering a critical insight into the battle between modern medicine and bacterial evolution, with a particular focus on new antibiotics to fight MDR-GN bacteria, especially against Acinetobacter baumannii, Enterobacterales, Pseudomonas aeruginosa, and Stenotrophomonas maltophilia.
The articles published in this Special Issue should collectively address various strategies employed by Gram-negative bacteria to counteract antibiotics, such as the upregulation of efflux pumps, modification of drug targets, and acquisition of resistance genes via horizontal gene transfer. Special attention should be given to the role of mobile genetic elements like plasmids and integrons in the spread of resistance traits, emphasizing the dynamic nature of this global health threat.
Advancements in genomic and proteomic technologies have enabled a deeper understanding of bacterial resistance mechanisms, facilitating the identification of novel targets for therapeutic intervention. This Special Issue aims to highlight several innovative approaches to overcoming resistance, including the development of new antibiotics that bypass known resistance mechanisms, the strategic use of combination therapies to reduce the selection pressure for resistant strains, and exploring alternative treatments such as bacteriophage therapy.
In summarizing the current state of research, this Special Issue aims to not only shed light on the molecular intricacies of antibiotic resistance in Gram-negative bacteria but also chart a course for future investigations. We hope to underscore the urgency of adopting a multidisciplinary approach to develop effective strategies against this ever-evolving threat, stressing the importance of global collaboration in the fight against antibiotic resistance.

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.
