Special Issue Information

Dear Colleagues,

We are delighted to announce our new Special Issue entitled "Antimicrobial Resistance in Foodborne Pathogens: Prevalence, Mechanisms, and Interventions". This comprehensive Special Issue seeks to address critical knowledge gaps concerning the emergence, dissemination, and persistence of antimicrobial resistance across the food production continuum. Our focus encompasses high-priority foodborne pathogens, including Salmonella spp., Campylobacter spp., Escherichia coli, and Listeria monocytogenes, with isolates sourced from diverse food production environments and clinical settings to provide a holistic understanding of resistance ecology.

We welcome investigations elucidating the genetic and phenotypic determinants governing resistance acquisition, expression dynamics, and transmission pathways. Additionally, we seek innovative research on intervention strategies to combat resistant foodborne pathogens. Submissions exploring novel approaches, such as bacteriophage therapy, competitive exclusion strategies, vaccination, and alternative antimicrobial compounds, are strongly encouraged, particularly those demonstrating translational potential for implementation across the farm-to-fork continuum. We sincerely invite contributions from researchers across multiple disciplines, including microbiology, genomics, epidemiology, food science, veterinary medicine, and public health. Original research, comprehensive reviews, and perspective articles addressing these critical aspects of antimicrobial resistance in foodborne pathogens are welcome for consideration.

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.

Antimicrobial resistance poses a growing threat to public health, and integrated surveillance strategies across environmental compartments such as treated wastewater and biosolids can substantially improve monitoring efforts. A key challenge is the diversity of available protocols, which complicates comparability for the concentration and detection of antibiotic resistance genes (ARGs), particularly in complex matrices. In this study, we compared two commonly used concentration methods—filtration–centrifugation (FC) and aluminum-based precipitation (AP)—and two detection techniques, quantitative PCR (qPCR) and droplet digital PCR (ddPCR), for the quantification of four clinically relevant ARGs: tet(A), blaCTX-M group 1, qnrB, and catI. Analyses were performed in both secondary treated wastewater and biosolid samples, including their purified bacteriophage-associated DNA fractions. Results showed that the AP method provided higher ARG concentrations than FC, particularly in wastewater samples. ddPCR demonstrated greater sensitivity than qPCR in wastewater, whereas in biosolids, both methods performed similarly, although ddPCR yielded weaker detection. Importantly, ARGs were detected in the phage fraction of both matrices, with ddPCR generally offering higher detection levels. These results provide comparative insights into established methodologies and highlight the value of selecting appropriate protocols based on matrix characteristics and surveillance objectives.
