Current Insights into Apicomplexan Parasites: Advances in the Control Strategies in Veterinary Science

About this Research Topic

Background

Apicomplexan parasites represent a diverse group of intracellular protozoans that affect both humans and animals, threatening public and animal health and welfare, causing a significant economic impact on the farming industry, and food security consequences. Representative species are Toxoplasma gondii, Neospora caninum, Eimeria spp., and Plasmodium spp. They exhibit a complex life cycle that encompasses several stages, either monoxenic or involving more than one host, such as merogony, gametogony, and sporogony.

Significant advances in next-generation technologies improved our understanding of parasite biology, host-parasite interaction, virulence, and immunology, enabling progress in diagnosis, control, and treatment. However, critical gaps remain that hinder the discovery of novel therapeutic targets and limit the availability of effective vaccines. Current control measures are constrained, and the emergence of drug-resistant parasites drives the global search for novel, cost-effective, and secure tools that are needed globally to control apicomplexan parasites that impair the health and welfare of livestock and poultry.

This Research Topic aims to collect new data addressing the development of novel control strategies for apicomplexan parasites of veterinary and economic significance. These contributions will provide a comprehensive overview of the role of these parasites that continue to pose significant challenges due to their complex life cycles, ability to establish chronic infections, and capacity to evade host immune responses. By addressing key gaps in our understanding of their biology, epidemiology, and host–parasite interactions, it will highlight novel approaches for prevention, diagnosis, new vaccines, antiparasitic drugs, and integrated control strategies. By bringing together multidisciplinary perspectives, this initiative aims to stimulate collaboration and knowledge exchange, contributing to the design of more effective tools to reduce the burden of apicomplexan parasites on human and animal populations.

This Research Topic welcomes original research, review, and minireview articles addressing parasite biology, epidemiology, molecular and immunological aspects of host–parasite interactions, and the development of innovative diagnostic, therapeutic, and preventive strategies. Specific themes include mechanisms of pathogenicity, drug resistance, novel chemotherapeutic agents, vaccine candidates, and integrated control approaches in animal production and public health contexts. Studies applying cutting-edge technologies such as genomics, transcriptomics, proteomics, or advanced imaging to explore apicomplexan biology are also encouraged.

Contributions that provide multidisciplinary insights, comparative studies across species, or translational perspectives linking veterinary and human health are particularly welcome. Together, these works will contribute to updating the state of the art and fostering collaboration in the field of apicomplexan parasitology. Importantly, advances in these areas could also have implications beyond animal health and welfare, paving the way for medical advances.

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?
