Special Issue Information

Dear Colleagues,

Technological innovation has greatly improved the efficiency and the welfare of poultry production, especially in relation to nutrition, housing, and health management.

Despite the great strides made in terms of disease control, respiratory and immunosuppressive viral diseases remain one of the main challenges in intensively reared poultry, while these infections can cause substantial economic losses themselves, and act as a trigger for even more serious bacterial disease.

We invite original research papers that address recent advances in the etiology, epidemiology, pathobiology, diagnosis, and control by vaccination of viral respiratory and immunosuppressive diseases of poultry. Studies on the major viral infections of poultry, such as infectious bronchitis (Avian coronavirus), turkey rhinotracheitis and swollen head Syndrome (Avian metapneumovirus), infectious laryngotracheitis (Gallid alphaherpesvirus 1), Newcastle disease (Avian orthoavulavirus 1), avian influenza (Influenza A virus), infectious bursal disease (Infectious bursal disease virus), chicken infectious anemia (Chicken anemia virus), Marek’s disease (Gallid alphaherpesvirus 2), and turkey hemorrhagic enteritis (Turkey siadenovirus A), are welcomed.  Minor, or newly observed, respiratory and immunosuppressive viral conditions will be also considered.  Additional topics may include the interaction between different pathogens in experimental or field conditions or the observation of well-known agents in unusual host 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.

To evaluate the recent evolution of CIAV in China, 43 flocks of chickens from the provinces of Henan, Jiangsu, Hubei, and Anhui were screened via polymerase chain reaction during 2020–2022. Of these, 27 flocks tested positive for CIAV nucleic acids, including 12 which were positive for other immunosuppression viruses. Additionally, 27 CIAV strains were isolated, and their whole genomes were sequenced. The AH2001 and JS2002 strains shared the highest identity at 99.56%, and the HB2102 and HB2101 strains shared the lowest identity at 95.34%. Based on the genome sequences of these strains and reference strains, a phylogenetic tree was constructed and divided into eight main branches. Most of the strains were grouped with the East Asian strains, whereas the HB2101 strain belonged to the Brazil and Argentina cluster. A recombination event was detected in multiple strains, in which AH2002 recombined from KJ728827/China/2014 (from Taiwan Province) and HN2203, and AH2202 recombined from KX811526/China/2017 (from Shandong Province) and HN2203. All the obtained strains had a highly pathogenic Gln amino acid site at position 394 of the VP1. Overall, our findings demonstrate the importance of CIAV monitoring and provide data that aid in understanding the evolution of CIAV. Full article
