Special Issue Information

Dear Colleagues,

Emerging and re-emerging viruses represent a growing global health concern due to their remarkable ability to evolve and adapt to new ecological niches. Arboviruses are particularly relevant within this group because of their intrinsic capacity to cross species barriers during transmission cycles. The intense and recurrent circulation of arboviruses such as dengue, chikungunya, Zika, yellow fever, Rift Valley fever, Japanese encephalitis, West Nile, Mayaro, and St. Louis encephalitis viruses in tropical and subtropical regions greatly increases the likelihood of novel viral variants or species arising. Developing effective strategies for surveillance, early detection, prediction, and control remains a major challenge, as these infections often present with overlapping clinical symptoms, which complicates differential diagnosis. Moreover, genetic and proteomic similarities among closely related viral species may hinder accurate molecular detection and genomic characterization.

This Special Issue welcomes contributions focusing on emerging and re-emerging viruses, with particular emphasis on arboviruses. We encourage submissions addressing viral detection in vectors, novel diagnostic methodologies, genomic and evolutionary analyses, and antiviral strategies. Reports describing the emergence or re-emergence of arboviruses in new geographic regions, as well as studies on sustainable vector control programs, are of special interest. Overall, this collection aims to provide an updated overview of innovative approaches to detect, analyze, and combat emerging viral threats.

  • Biotechnological uses of vector control;
  • Characterization of new arboviruses and their mechanisms;
  • Molecular and evolutionary aspects of arboviruses;
  • Interactions between insects and arboviruses;
  • Medical entomology and zoonoses;
  • Epidemiology and public health;
  • Neglected diseases;
  • Vector-borne diseases;
  • Discovery of antivirals.

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 250 words) can be sent to the Editorial Office for assessment.

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. Microorganisms 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 2700 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.

Abstract
In this study, we identified a novel partitivirus infecting industrial hemp (Cannabis sativa L.), named as industrial hemp cryptic virus (IHCV). The complete genome sequence of IHCV comprises two RNA segments: dsRNA1 (1683 nt) encoding an RNA-dependent RNA polymerase (RdRp, 481 aa), [...] Read more.
In this study, we identified a novel partitivirus infecting industrial hemp (Cannabis sativa L.), named as industrial hemp cryptic virus (IHCV). The complete genome sequence of IHCV comprises two RNA segments: dsRNA1 (1683 nt) encoding an RNA-dependent RNA polymerase (RdRp, 481 aa), and dsRNA2 (1669 nt) encoding a coat protein (CP, 417 aa). Comparative sequence analyses revealed that RdRp shares 68.10% amino acid similarity with the Citrullus lanatus cryptic virus (CiLCV), while the CP exhibits 35.80% similarity with the vitis cryptic virus (VCV). Moreover, phylogenetic analysis showed that both the RdRp and CP proteins of IHCV clustered together with the pepper cryptic virus 1 (PCV1), which belongs to the genus Deltapartitivirus. Seeds detection assays revealed seed infection rates ranging from 20% to 90% among different industrial hemp cultivars. This is the first report of a novel partitivirus virus infecting industrial hemp. Full article
