About this Research Topic

Background

Antibiotic-resistant microbes are regarded as one of the world's greatest threats today. Due to the growing number of infections caused by these bacterial pathogens, experts have estimated that more people will die from infectious diseases than cancer by 2050.

The plant kingdom contains over 422,000 plant species. Being sedentary and lacking an adaptive immune system, plants rely on defensive chemicals to fight pathogens and deter pathogenic microorganisms. Compared to synthetic organic small molecules, natural products have unique scaffolds and structural complexity that is not always readily attainable by synthesis. Only a small portion of the Globe’s natural biota has been chemically studied and tested pharmacologically, despite many anti-cancer and antibiotic agents being discovered from this resource. Consequently, natural products still represent an enormous reservoir of novel small molecules of privileged structures for the discovery of antimicrobial agents.

The prospect of novel antibiotics from marine sources is high. Marine organisms thrive successfully despite harsh stress factors (such as heavy predation, fouling of neighbouring sites, physical stress factors e.g., changing salinity) as their biological capability is closely linked to their chemical adaptation, which makes them highly interesting candidates for bioprospecting. A fair number of these compounds owe their existence to environmental pressures and score as “hits” in antimicrobial driven bioassays thereby making these secondary metabolites interesting candidates for drug discovery. It has been shown that marine organisms thrive despite pronounced biotic pressures through their arsenal of chemical defence, thereby providing a link between chemical ecology and pharmacology.

An approach for solving the supply problem inherent to marine natural products derived from macroorganisms, is the isolation and fermentation of microorganisms (bacteria, fungi and microalgae) that are in many cases suspected to be involved in the biosynthesis of bioactive natural products recovered from macroorganisms. Many marine invertebrates are filter feeders and consume microorganisms from the inhaled sea water by phagocytosis. In addition, marine invertebrates are known to harbour microorganisms that include bacteria, cyanobacteria and fungi within their tissues, where they may reside in the extra- and even intracellular space. The sea holds a diversity of macroorganisms but contains an even more impressive arsenal of microorganisms such as bacteria, cyanobacteria, fungi and others. Marine microorganisms are now considered to be the true producers of bioactive constituents that are recovered from sponges, mollusks and other invertebrates. The diversity and the sheer number of marine derived microorganisms is impressive. For bacteria alone, the oceans are known to contain an average of 105 -106 bacteria/mL of sea water. This amounts to an estimated weight of 1012 tons of bacteria that live in the world´s oceans. The immense biodiversity apparent in the marine environment is a potentially rich source of novel antibiotics. Because of the growth in antibiotic resistance, there is a pressing need for novel products, particularly with new mechanisms of action – only two completely new classes of antibiotics have been introduced in the last 30 years. By accessing unique sources of small molecules that are likely to have unusual chemical features, the marine environment is well positioned to be a good source of new leads for valuable novel antibiotics with unique chemistry/potent antibiotic activity.

With this research topic in mind, we will highlight the latest advances in research related to the antimicrobial properties of natural products.

We welcome submissions that describe current trends and recent advances in discovering novel antimicrobial natural products. These include original research, reviews, mini-reviews, brief research reports and articles describing clinical research on the antimicrobial properties of extracts, fractions, purified compounds, herbal products and synergistic mixtures against microorganisms encountered in human infectious diseases. In this research topic, we also encourage submissions related to the identification of new antimicrobials using novel drug discovery technologies.

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?
