New Obstacles in Bacterial, Fungal and Viral Infections: Antimicrobial Resistance and Emerging Pathogens

Dear Colleagues,

The COVID-19 pandemic has drawn attention to the field of infectious diseases, demonstrating how the never-ending confrontation with the microbial world is more intense than ever. Before the beginning of the pandemic, antimicrobial resistance seemed to represent the most important challenge and it is still a threat of utmost importance.

Nevertheless, the appearance and the worldwide spread of SARS-CoV-2, that is continuing its extraordinary evolutionary trajectory, has shown the vastness of the array of infective menaces, including emerging and re-emerging pathogens of different nature: viral, bacterial, fungal.

Climate change, for instance, implying global warming, could drive the evolution of novel strains of thermotolerant fungi.

The tremendous selective pressure linked with very frequent antibiotic use, either for human or animal purposes, may favor the development of superbugs with no reliable therapeutic options.

Viral spillover has become more frequent due to several human activities, for instance, land use expansion.

This Special Issue aims to collect reviews and original articles addressing these topics to offer new insights from multiple perspectives: epidemiological, aetiological, diagnostic and therapeutic.

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. Microorganisms 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.
