Special Issue Information
Dear Colleagues,
In recent decades, the increased detection of Gram-negative bacteria producing extended-spectrum β-lactamases (ESBLs) and/or carbapenemases has become an urgent public health concern. These enzymes confer resistance to antimicrobials that are generally used as a last-resort therapy for these pathogens, endangering available treatment options.
In particular, ESBLs confer resistance to all β-lactams and monobactams but are susceptible to carbapenems. Carbapenemases confer resistance to all β-lactams, including carbapenems. The genes that encode for ESBLs (e.g., blaCTX-M) and carbapenemases (e.g., blaKPC, blaNDM) disseminate vertically, via successful clones, and horizontally, through the transfer of genetic elements inter- and intraspecies. In addition, the evolution of resistance in post-COVID-19 times has led to the dissemination of Enterobacterales harboring multiple carbapenemases and ESBLs.
This Special Issue of Pathogens, “Beta-Lactamases-Producing Gram-Negative Bacteria in the 21st Century”, encourages submissions of original research papers and reviews that can bring an understanding and propose solutions to the main challenges in the subject. Areas of particular interest include drivers of transmission within the hospital, the community, to food and wild animals and the environment, as well as epidemiology and surveillance of Enterobacterales and non-fermentative Gram-negative bacteria and methodologies to decrease detection time and novel approaches to guide treatment.
We welcome and look forward to publishing your research.

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. Pathogens 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 2200 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.

Benefits of Publishing in a Special Issue
- Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
- Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
- Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
- External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
- e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.
