Special Issue Information

Dear Colleagues,

Bacteriophages (or phages) are obligatory parasites of bacterial hosts regardless of their lifestyles and replicating cycles. Although phages are the most diverse and abundant biological entities on the planet, their implications in different ecosystems are, as of yet, poorly defined. Food production and processes are no exception. In ecological niches from raw plants to final products, grey zones remain in phage diversity and its impact on bacterial populations, in particular in region-specific and traditional fermented products including fermented dairy, vegetable and meat products. Temperate or virulent, phages can either be considered beneficial or a threat, depending on their host species and habitat.

The food industry commits significant effort to improve the quality and safety of their products. Many manufacturing processes are critically dependent on the consistent performance of starter cultures or beneficial microorganisms that may contribute to their complex microbiota. In this context, bacteriophages pose an ever-present threat as they possess the potential to destroy the starter cultures or bacteria contributing positively to population dynamics, thereby affecting product quality. Conversely, as natural and specific bacteria killers, phages may be used to increase food safety and quality by limiting the presence of spoilage microorganisms in manufacturing processes or food-borne pathogens in foodstuffs.

Efforts in overcoming the difficulties of the complexity of food matrices, in vivo or field experiments lead to expansion of phage diversity and their exploitation, demonstrating several possible applications for phage-related products across the entire food production chain. Unravelling phage-host interactions is important for the rational development of phage cocktails and phage-based tools such as biosensors or biocontrol agents. In this context, the characterization of viral host-binding machineries and their bacterial receptors, as well as the attack and defence mechanisms are highly valuable.

For this special issue, we invite authors to submit original and unpublished research papers, reviews, or short communications covering different research topics related to the roles or the applications of phages in food processes or agriculture. This may include phage ecology and phage-host interactions in related fields, phage-based biosensors or biocontrol of food-borne pathogens or spoilage bacteria, and exploitation of phage proteins.

Manuscripts can be submitted until the deadline. All papers will be 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. Viruses 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 2400 CHF (Swiss Francs).

In this study, we examined the effect of a bacteriophage cocktail (tentatively designated as the Foodborne Outbreak Pill (FOP)) on the levels of Listeria monocytogenes in simulated small intestine, large intestine, and Caco-2 model systems. We found that FOP survival during simulated passage of the upper gastrointestinal was dependent on stomach pH, and that FOP robustly inhibited L. monocytogenes levels with effectiveness comparable to antibiotic treatment (ampicillin) under simulated ilium and colon conditions. The FOP did not inhibit the commensal bacteria, whereas ampicillin treatment led to dysbiosis-like conditions. The FOP was also more effective than an antibiotic in protecting Caco-2 cells from adhesion and invasion by L. monocytogenes (5-log reduction vs. 1-log reduction) while not triggering an inflammatory response. Our data suggested that the FOP may provide a robust protection against L. monocytogenes should the bacterium enter the human gastrointestinal tract (e.g., by consumption of contaminated food), without deleterious impact on the commensal bacteria.
