Dear Colleagues,

For many years, the most known bacterial carcinogen was Helicobacter pylori. With the development of science, especially molecular diagnostics, including NGS, it has been noticed that other bacteria may also be involved in cancer. A particular role is currently attributed to oral pathogens (e.g., Streptococcus sp., Prevotella sp., Fusobacterium sp., Porphyromonas gingivalis, and Capnocytophaga gingivalis). These pathogens can have an impact on the development of oral and esophageal cancers. Many works have also shown that mainly Fusobacterium nucleatum and Porphyromonas gingivalis play an important role in the development of colorectal and pancreatic cancer. On the other hand, already in the nineteenth century, Dr. William Coley presented anti-cancer microbes, now called the Coley’s toxin. Anti-carcinogenic activity may also exert probiotic bacteria (e.g., Lactobacillus sp.). For this Special Issue, we invite you to send original or review papers on aspects of bacterial carcinogenesis and the anti-cancer activity of bacteria.

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.
