Special Issue Information
Dear colleagues,
Listeria monocytogenes is a Gram-positive microorganism that can cause the well-known listeriosis disease, or so-called “YOPI”, an infection of great concern especially for young, old, pregnant, and immune-compromised people.
This bacterium is frequently found in various foodstuffs, mainly those characterized by pH values higher than 4.4. To date, several strategies are hypothesized to inhibit the growth of undesirable microorganisms, such as technological processing, antimicrobial substances or protective microbial cultures. Unfortunately, in the case of several food types, sub-lethal pH values may induce resistance mechanisms to acid stress, which makes the cells more resistant to severe acid conditions. The tolerance to low pH values (can survive but not grow from 3.3 to 4.2) in addition to high salt concentrations, the ability to grow at refrigeration temperature as well as the ability to form biofilms allow the survival of this pathogen in several foods, including ready-to-eat foods. Understanding the Listeria monocytogenes virulence, antimicrobial resistance mechanisms, and environmental stress adaptation could contribute to the development of novel and effective antimicrobial strategies based on protective methods.
The Special Issue encourages the publication of original research articles on the following main topics:
- Listeria monocytogenes virulence;
- Proteomic and metabolomics-based approaches to detect L. monocytogenes;
- Antimicrobial resistance mechanisms in L. monocytogenes;
- Gene expression in stress responses;
- Stress protein expression in L. monocytogenes or in L. monocytogenes surrogate species;
- L. monocytogenes susceptibilities;
- Novel anti-Listeria strategies;
- Challenge test to validate anti-Listeria effectiveness of novel protective strategies.

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. Biology 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.
