Special Issue Information

Dear Colleagues,

Avian viruses represent a persistent and growing challenge to animal health, public health, and global food security. The increasing frequency of emerging and re-emerging avian viral diseases, combined with intensified poultry production, global trade, wildlife migration, and environmental change, has heightened the risk of viral transmission within avian populations and across species barriers. These dynamics underscore the urgent need for integrated research efforts aimed at understanding avian virus transmission pathways, and developing effective prevention and control strategies.

This Special Issue, “Avian Virus Transmission and Prevention Strategies”, aims to provide a comprehensive platform for advancing knowledge on the epidemiology, ecology, and control of viruses affecting avian species. Understanding the mechanisms underlying virus transmission and implementing effective prevention strategies are therefore critical.

The scope of this Special Issue includes, but is not limited to, the following topics:

  • Molecular epidemiology and evolutionary dynamics of avian viruses;
  • Transmission routes and risk factors in domestic and wild bird populations;
  • Virus–host interactions and adaptation mechanisms;
  • Cross-species transmission and zoonotic potential of avian viruses;
  • Surveillance systems, early warning approaches, and outbreak investigations;
  • Biosecurity measures, vaccination strategies, and disease prevention programs;
  • The application of novel diagnostic, bioinformatics, and modeling tools in avian virology.

This Special Issue welcomes original research articles, review papers, short communications, and perspectives that contribute to a deeper understanding of avian virus transmission and prevention. By bringing together high-quality and multidisciplinary research, this collection aims to serve as a valuable resource for researchers, veterinarians and epidemiologists working to reduce the burden of avian viral diseases and strengthen preparedness against future outbreaks.

We look forward to receiving your contributions.

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-anonymized 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).

Viral infections remain a major threat to poultry health and production worldwide, highlighting the need for novel antiviral strategies. This study evaluated the in vitro antiviral and virucidal activities of six Thai medicinal plant extracts against herpesvirus of turkey (HVT), a non-oncogenic avian herpesvirus widely used as a live vaccine vector and employed here as a preliminary in vitro screening model. Cytotoxicity, total phenolic content (TPC), and antioxidant capacity were assessed using the MTT, Folin–Ciocalteu, DPPH, ABTS, and FRAP assays. Among the tested extracts, Caesalpinia sappan (CS) and Persicaria odorata (PO) exhibited the highest TPC and antioxidant activities and were selected for further antiviral evaluation. Both extracts significantly reduced HVT infectivity, infectious viral titers, and intracellular viral DNA levels in DF-1 cells (p < 0.01). CS produced lower infectious viral titers (1.995 × 104 TCID50/mL) than PO (8.24 × 104 TCID50/mL); however, both extracts significantly reduced viral titers compared with the untreated control (1.78 × 106 TCID50/mL). In the virucidal assay, pre-incubation of HVT with CS and PO significantly reduced infectious virus titers to 4.64 × 104 and 2.15 × 104 TCID50/mL, respectively, compared with the untreated control (1.47 × 106 TCID50/mL) (p < 0.01). These findings identify C. sappan and P. odorata as promising sources of plant-derived compounds for future investigation as antiviral agents against avian herpesviruses. However, additional studies using virulent MDV-1, independent biological replicates, and in vivo models are required before their potential application to Marek’s disease control can be established.
