Special Issue Information

Dear Colleagues,

Bacteriophages (phages), viruses naturally killing bacteria, have been proposed as a sustainable and efficient alternative to antimicrobials to ensure food production and safety by targeting plant, animal, and foodborne pathogens. Despite the recent advances in phage biology and biotechnology, the path to bringing phage products from the laboratory to the market remains a challenge. It is for example necessary to ensure phage safety and efficiency in very complex systems, such as food matrices and animals’ gut, and agricultural environments to provide data about phage stability and comply with industrial scale procedures and legislation.

This Special Issue invites research articles and reviews on the use of phages to control plant, animal, and foodborne pathogens in food production. It includes not only the isolation and characterization of new phage collections to target foodborne and zoonotic pathogens, but also metagenomic-based approaches, methods to quantify and track the used phages, and strategies to increase their efficacy and safety, including novel delivery strategies in food, plant, and animal production. Novel and multidisciplinary strategies to overcome the limitations of the state-of-the-art phage biocontrol measures are particularly welcome.

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.

Salmonella spp. is one of the most common foodborne pathogens worldwide; therefore, its control is highly relevant for the food industry. Phages of the Felixounavirus genus have the characteristic that one phage can infect a large number of different Salmonella serovars and, thus, are proposed as an alternative to antimicrobials in food production. Here, we describe two new members of the Felixounavirus genus named vB_Si_35FD and vB_Si_DR94, which can infect Salmonella Infantis. These new members were isolated and sequenced, and a subsequent comparative genomic analysis was conducted including 23 publicly available genomes of Felixounaviruses that infect Salmonella. The genomes of vB_Si_35FD and vB_Si_DR94 are 85,818 and 85,730 bp large and contain 129 and 125 coding sequences, respectively. The genomes did not show genes associated with virulence or antimicrobial resistance, which could be useful for candidates to use as biocontrol agents. Comparative genomics revealed that closely related Felixounavirus are found in distinct geographical locations and that this genus has a conserved genomic structure despite its worldwide distribution. Our study revealed a highly conserved structure of the phage genomes, and the two newly described phages could represent promising biocontrol candidates against Salmonella spp. from a genomic viewpoint.

Bacterial leaf blight, which is caused by Xanthomonas axonopodis pv. allii, annually causes significant yield losses to Welsh onion in many producing countries, including Vietnam. In this study, we isolated and characterized lytic phages Φ16, Φ17A and Φ31, specific to X. axonopodis pv. allii and belonging to a new phage species and genus within the Autographiviridae, from four provinces in the Mekong Delta of Vietnam. Moreover, we evaluated their efficacy for the biocontrol of leaf blight in greenhouse and field conditions. When applying the three highly related phages individually or as a three-phage cocktail at 108 PFU/mL in greenhouse conditions, our results show that treatment with Φ31 alone provides higher disease prevention than the two other phages or the phage cocktail. Furthermore, we compared phage concentrations from 105 to 108 and showed optimal disease control at 107 and 108 PFU/mL. Finally, under field conditions, both phage Φ31 alone and the phage cocktail treatments suppressed disease symptoms, which was comparable to the chemical bactericide oxolinic acid (Starner). Phage treatment also significantly improved yield, showing the potential of phage as a biocontrol strategy for managing leaf blight in Welsh onion. Full article
