Special Issue Information
Dear Colleagues,
This issue of Microorganisms provides new insights into a critical theme for aquaculture and public health regarding the relationship between antibiotic use, the traditional and emerging pathogenesis of infectious diseases, and the rise of resistant microbial strains.
The ongoing intensification of aquaculture practices has directly impacted fish health, leading to increasingly frequent and severe disease outbreaks. Despite advancements in strategies such as vaccination and the use of immunostimulants, many farmers, particularly in developing countries, continue to rely on antibiotics. What might seem like negligence is often rooted in a lack of knowledge about the impact of antibiotics on fish disease pathogenesis, coupled with the limited availability of technologies developed for regionally important species.
The biological and molecular responses of fish and microorganisms—and the interactions between them in the presence of antibiotics—have been pivotal areas of study in aquaculture and human health worldwide. As a result, significant progress has been made toward finding alternatives to antibiotics. However, more comprehensive knowledge is still needed to enhance the biosecurity of aquaculture systems.
In this issue, we focus on the following:
- New insights into microbial resistance to antibiotics;
- Host–pathogen interactions in the presence of antibiotics;
- How antibiotics (and other substances used in aquaculture) alter the pathogenesis of fish diseases; and
- Novel alternatives to antibiotic use in aquaculture.
Reviews, original research, and communications on any aspect of the ‘Pathogenesis and Antibiotic Resistance Mechanisms of Fish Pathogens’ will be welcome.

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.
