Special Issue Information

Dear Colleagues,

Ticks are ubiquitous arthropods increasingly recognised as significant vectors of pathogens that can adversely affect animal and human health. Increased global travel, population explosion and global warming may be directly related to a shift in the distribution and prevalence of ticks and the pathogens they transmit. Climate change may be directly related to extended seasonal tick activities, expansion of their geographic range and enhanced pathogen development in these ticks. The complex interplay among these factors can present substantial challenges to tick and tick-borne disease surveillance, prevention and control. As such there is also the need for advanced molecular methods for the effective detection of emerging and re-emerging tick-borne pathogens.

This special issue welcomes researchers and reviewers with an interest in climate change and tick ecology, emerging and re-emerging tick-borne diseases and novel diagnostic approaches to tick-borne pathogens with a One Health approach to ticks and their pathogens across the globe. This special issue aims to foster interdisciplinary research and collaboration with a hope to gain a deeper understanding of the complex factors which may be driving the emergence and spread of tick-borne diseases.

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. Pathogens 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 2200 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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Throughout Europe, including Poland, Ixodes ricinus ticks are the main vector of numerous pathogenic agents that pose a serious threat to public health. Southern Poland attracts many tourists with its scenic landscapes and abundant recreational opportunities. These areas are ideal habitats for wild fauna, which serve as the main reservoirs and hosts for these pathogens and ticks. The large population and biodiversity of these hosts facilitate the proliferation of ticks. The aim of this study was to determine the potential exposure of humans to ticks and tick-borne pathogens such as Borrelia burgdorferi sensu lato, Anaplasma phagocytophilum, and Babesia spp., along the nature-educational and tourist trails of the Poprad Landscape Park. From 2020 to 2021, ticks were collected using the flagging method on three tourist trails and nature-educational paths within the Poprad Landscape Park. DNA was isolated from 213 I. ricinus ticks using the ammonia method. To detect pathogens in ticks, PCR and nested PCR methods were used. To detect B. burgdorferi s.l. and A. phagocytophilum, two pairs of primers specific to the flaB gene fragment and 16S rRNA gene fragment were used, respectively. For Babesia spp. detection, primers specific to the 18S rRNA gene were used. The amplification products were separated electrophoretically and visualized under ultraviolet light. In total, among the 213 examined ticks, B. burgdorferi s.l. was detected in 31% of the samples. Neither A. phagocytophilum nor Babesia spp. were detected in the studied material. These results indicate a potentially high risk of ticks and tick-borne B. burgdorferi s.l. infections for residents and tourists in the recreational areas of the Poprad Landscape Park. Full article
