Special Issue Information

Dear Colleagues,

Avian viral pathogens remain a major global concern in both domestic and wild avian species. Viral evolution, cross-species viral transmission as well as host and environmental factors can play major roles in the spread and pathogenicity of viral infections in domestic and wild avian species. Recent epidemics with transboundary and potentially zoonotic viruses such as highly pathogenic avian influenza have resulted in significant socioeconomic consequences. These challenges stem from their negative impact on animal health and welfare, public health, and the disruption of commercial poultry markets. In addition, avian viral pathogens can have devastating effects stemming from the impact of subclinical disease, morbidity and mortality and the challenges and costs associated with diagnostics, surveillance, management and in some cases eradication.

With this in mind, we are excited to announce the upcoming Special Issue on Avian Viruses. The scope of this issue will cover the pathogenesis and pathology of avian viral diseases, the emergence of novel viral pathogens, viral evolution including viral phylogeny, pathogenicity, routes of transmission, surveillance and principles of control and eradication. We encourage you to submit your original research, review, case report or short communication related to viruses that impact avian species.

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. Animals is an international peer-reviewed open access semimonthly 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 2400 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.

Fowl adenovirus 1 (FAdV-1) is the main cause of gizzard erosion in chickens. Whole genome sequencing and sequence analyses of 32 FAdV-1 strains from a global collection provided evidence that multiple recombination events have occurred along the entire genome. In gene-wise phylogenies, only the adenoviral pol gene formed a tree topology that corresponded to whole genome-based phylogeny. Virus genetic features that were clearly connected to gizzard erosion were not identified in our analyses. However, some genome variants tended to be more frequently identified from birds with gizzard erosion and strains isolated from healthy birds or birds with non-specific pathologies tended to form common clusters in multiple gene phylogenies. Our data show that the genetic diversity is greater, and the evolutionary mechanisms are more complex within FAdV-1 than previously thought. The implications of these findings for viral pathogenesis and epidemiology await further investigation. Full article
