Dear Colleagues,

Genus Campylobacter, in particular, C. jejuni and C. coli, are well-recognized as one of the leading causes of gastrointestinal illness worldwide, with possible consequences such as the development of Guillain–Barré syndrome (GBS), which is a rare disorder where a person’s own immune system damages their nerve cells, causing muscle weakness and, sometimes, paralysis. According to the European Food Safety Authority, approximately 220 thousands human campylobacteriosis were confirmed in 2019, in the EU and its occurrence rates was estimated to be 59.7 per 100,000 population (https://0-www-ncbi-nlm-nih-gov.brum.beds.ac.uk/pmc/articles/PMC7913300/). To date, epidemiological surveillance has mounted evidence that these pathogens could be mainly transmitted via poultry and ruminants, throughout the food chain, to humans, whereas a part of human campylobacteriosis has originated from other sources, such as wild birds and hostile environments. The latter issue thus suggested the possible transmission vehicle of wild animals or environments of the pathogenic microorganism. Thus, the source attribution study, as well as monitoring and improvement of hygienic control at slaughter and processing facilities of the associated foods, have social impacts for developing feasible strategies to reduce human infection.

Among the genus Campylobacter, other species, such as C. lari, C. hyointestinalis, C. fetus are also linked to a series of human infection. The impact of these infectious agents on health ramified into a broader social need to address not only the biology, but also the social, economic, and psychological costs of the associated diseases on our lives. For this Special Issue, we sincerely invite you to send the original articles or review articles on aspects of the biology relating to the genus Campylobacter, from multiple viewpoints such as food safety, microbiology, infection biology, and molecular epidemiology.

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 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.
