About this Research Topic

Background

Bacteria, fungi, viruses and parasites, among others, threaten the health and welfare of all terrestrial and aquatic animal species, including companion animals, livestock, fish and wildlife. This can lead to high rates of morbidity, mortality, increased economic costs, reduced food production and conservation risks. This situation is aggravated by the fact that many of these pathogens can also cause disease in humans, threatening global public health. In addition, recent decades have seen the emergence and spread of agents with new virulence characteristics, antimicrobial resistance and evasion of the immune response.
In a globalised world, the emergence and spread of pathogens is increasingly easy and expected, and can even cause large outbreaks. Therefore, knowledge of the molecular epidemiology of these pathogens, including geographical distribution, virulence, resistance determinants, genomic patterns, is essential to establish appropriate prevention and control measures, in an integrated and multidisciplinary manner, under the concept of One Health.

Genomic changes in infectious agents not only correspond to a phenomenon of microbial evolution, but in many cases involve changes in their pathogenicity, virulence, dissemination capacity, resistance to therapeutical and vaccinal alternatives, and challenge current diagnostic tools. This risk highlights the need to conduct epidemiological studies that describe the current situation of these pathogens and provide relevant information to establish updated prevention and control strategies.
Therefore, the goal of this research topic is to contribute to the update on the molecular epidemiology of pathogens that threaten animal health and that can also affect humans.
To this end, this article collection aims to collect articles describing molecular epidemiological patterns of various infectious agents both globally and locally, including recent advances in pathogenesis, dissemination of critical risk clones, molecular patterns of antimicrobial resistance, among others.

The goal of this Research Topic is to collect research that will inform molecular epidemiology of infectious agents under a “One Health” approach. We particularly welcome manuscripts and reviews focusing on, but not limited to:
-Advances in microbial pathogenesis of animal and zoonotic agents to improve understanding of their host-pathogen interaction..
-Genomic characterization of infectious agents, focusing on virulence determinants, antimicrobial resistance and identification of vaccine targets.
-New insights into geographic distribution of molecular markers of interest in pathogens, including dissemination of critical clones or highly relevant strains.
-Development or validation of rapid, specific and sensitive diagnostic techniques for the identification of new molecular patterns of interest.

Keywords: Zoonoses, pathogen, surveillance, molecular, epidemiology

Important note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

  In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?

  Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.

• Who leads a Research Topic? 

  A team of guest editors (called topic editors) lead their Research Topic. This editorial team oversees the entire process, from the initial topic proposal to calls for participation, the peer review, and final publications.

  The team may also include topic coordinators, who help the topic editors send calls for participation, liaise with topic editors on abstracts, and support contributing authors. In some cases, they can also be assigned as reviewers.

• What is the role of a topic editor?

  As a topic editor (TE), you will take the lead on all editorial decisions for the Research Topic, starting with defining its scope. This allows you to curate research around a topic that interests you, bring together different perspectives from leading researchers across different fields and shape the future of your field. 

   

  You will choose your team of co-editors, curate a list of potential authors, send calls for participation and oversee the peer review process, accepting or recommending rejection for each manuscript submitted.

• What support will I receive when editing a new Research Topic? 

  As a topic editor, you're supported at every stage by our in-house team. You will be assigned a single point of contact to help you on both editorial and technical matters. Your topic is managed through our user-friendly online platform, and the peer review process is supported by our industry-first AI review assistant (AIRA).

• As a junior researcher, can I be involved in editing a Research Topic? 

  If you’re an early-stage researcher, we will offer you the opportunity to coordinate your topic, with the support of a senior researcher as the topic editor.
