Special Issue Information

Dear Colleagues,

During the past decade, emerging vector-borne diseases and zoonotic diseases have occurred in areas where they had been previously eradicated or never been recorded before. The objectives of the second edition of this Special Issue are the following: (i) understanding the drivers of these diseases’ (re-)emergence; (ii) prioritization of these diseases and/or their vectors based on a multidisciplinary and evidence-based method; (iii) assessment of their spatio-temporal pattern (trend observation or trend analysis); (iii) signal capture of these diseases’ (re-)emergence; (iv) epidemiology of these diseases including participatory epidemiology and citizen science; (v) improvement of laboratory diagnostic capacities towards these diseases; (vi) estimation of their the costs for animals, environment and humans in case of zoonoses; and (vii) proposition of some mitigation measures or strategies to decrease their impacts/consequences on the host population(s), including biosecurity. Review papers including systematic reviews and meta-analyses as well as original papers on the matter that contribute to the outlined objectives are welcome. The second edition of this Special Issue is a perfect opportunity to combine several disciplines to better understand the emerging vector-borne diseases and zoonotic diseases.

I would like to invite colleagues investigating any of the emerging vector-borne diseases and zoonotic diseases within the above objectives to submit their manuscripts to this Special Issue in the form of original research and reviews.

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.

This study evaluated the genetic diversity and potential drug resistance markers in Plasmodium vivax isolates from Panama, a country in Mesoamerica, aiming to eliminate local malaria transmission. We analyzed 70 P. vivax samples collected between 2004 and 2020 from endemic regions in Eastern and Western Panama, as well as imported cases. Four drug resistance genes (pvcrt-o, pvmdr1, pvdhfr, and pvdhps) were sequenced and analyzed. Our findings reveal low genetic diversity in P. vivax populations from Western Panama, indicating clonal expansion, while Eastern Panama exhibits higher diversity, influenced by higher transmission rates and imported cases. No mutations were detected in pvcrt-o, and the prevalence of pvmdr1 mutations (Y976F and F1076L) linked to chloroquine was observed at low frequencies, primarily in imported samples. In pvdhfr, antifolate-resistant mutations S117N and S58R were detected in 14.3% of samples, predominantly from Eastern Panama near the Colombian border. Phylogenetic and haplotype network analyses highlighted distinct genetic clustering, supporting the influence of imported cases on local parasite diversity. These results provide a baseline for the molecular surveillance of P. vivax in Panama and emphasize the need for the continued monitoring of genetic diversity and drug resistance to guide regional malaria elimination efforts, particularly in areas with high cross-border migration.

Bovine trypanosomoses, caused by Trypanosoma vivax, is a disease present in African and South American countries. This haemoflagellate protozoan parasite, as well as Anaplasma marginale and Babesia spp., are microorganisms that have a blood tropism, mainly causing fever and anaemia, which reduces the productive capacity of dairy or meat farms. This study aimed to detect T. vivax and other blood parasites in bovine herds in the Galapagos Islands. A total of 170 blood samples from bovines in 19 farms on Santa Cruz Island (the most populated) were collected and analyzed using different PCR techniques: Da-PCR and CatL-PCR to detect Trypanosoma vivax, CatL-PCR to detect Trypanosoma theileri, ESAG-PCR to detect Trypanosoma evansi, 18S rRNA-PCR to detect Babesia spp., rap-1-PCR to detect Babesia bovis, hyp-PCR to detect Babesia bigemina, and msp5-PCR to detect A. marginale. The prevalence of T. vivax, B. bovis, B. bigemina, and A. marginale was estimated as 14.7%, 11.2%, 14.7%, and 67.1%, respectively. In this study, the presence of four haemotropic agents was evidenced in 26.3% (5/19) of the farms. Coinfected cattle (A. marginale, B. bovis and B. bigemina) had significantly higher body temperatures compared to others (two-sample Wilcoxon rank-sum test; p-value = 0.047). The molecular techniques used in this study demonstrated the presence of T. vivax and B. bovis in cattle from Santa Cruz Island in the Galapagos for the first time. The study also investigates the relationship between T. vivax, A. marginale and Babesia spp., making a significant contribution to the field of veterinary medicine. Full article
