Special Issue Information

Dear Colleagues, 

We are pleased to invite submissions of manuscripts to a Special Issue entitled “Pathology in Poultry Production”. 

The production of poultry is vital for global food security; however, the intensification of poultry production has led to an increase in challenging diseases with the potential to threaten animal welfare and public health. A thorough understanding of poultry pathology, including emerging pathogens, antimicrobial resistance, immunology, immunosupression, and diagnostics, is essential for sustainable production. In many cases, histopathology is also crucial for final diagnosis.

The aim of this Special Issue is to compile cutting-edge research that advances poultry health through innovative diagnostic, preventive, and therapeutic approaches across commercial and backyard production systems. 

We welcome original research articles, case studies describing emerging diseases, and reviews on topics including viral diseases, bacterial infections, parasitic diseases, immunopathology, metabolic disorders, neoplastic diseases, and diagnostic innovations. 

I look forward to receiving your contributions.

Prof. Dr. Michał Gesek
Guest Editor

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-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). 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.

Wooden Breast (WB) and White Striping (WS) are prevalent myopathies affecting the Pectoralis major (PM) muscle of modern broiler chickens, with significant implications for animal welfare and meat quality. This pilot study aimed to characterize proteomic alterations associated with increasing severity of WB and WS in the PM of Hubbard × Ross 708 broilers. Muscle samples (n = 12) were previously categorized into four severity ranks based on established macroscopic criteria. Presently, proteins were extracted and analyzed using LC-MS/MS-based shotgun proteomics. Statistical comparisons between groups were performed using Generalized Linear Models. Fibronectin 1, fibrinogen alpha chain, musculoskeletal embryonic nuclear protein 1, glutathione S-transferase 2, calsequestrin-2, and endoplasmin emerged as potential biological markers and their prospective roles in the pathogenesis of these myopathies are discussed. Our findings suggest a progressive alteration of the muscle proteome with increasing disease severity, highlighting pathways related to muscle structure, metabolism, and stress response. These results aid in providing new insights into the molecular mechanisms underlying WB and WS and may inform future research on genetic and management strategies. As a pilot study, these findings warrant further investigation in larger cohorts and different commercial lines. Full article

Ascaridia nymphii is a roundworm species affecting domestic avian species, initially described in 2015. One pen-reared, 4-year-old, female American Show Racer pigeon (Columba livia f. domestica) was submitted to the California Animal Health and Food Safety Laboratory System (CAHFS) Turlock branch, University of California–Davis, for postmortem examination and diagnostic work-up. Grossly, large numbers of ascarids were in the lumen of the proventriculus, gizzard, and duodenum, and a small number was present in the lumen of the trachea, esophagus, and crop. A focal, coiled adult nematode was embedded in the hepatic parenchyma. Ascarids were tan and measured approximately 3.5–4.5 cm in length. The liver was moderately enlarged, green-tinged, and had small, firm, and off-white scattered nodules. Microscopically, we observed multifocal to coalescing granulomas containing intralesional nematodes delineated by necrotic debris, multinucleated giant cells, eosinophilic and heterophilic inflammation, hemorrhage, and bacterial colonies in the liver. The genotypic characterization of the Ascaridia sp. in our case (GenBank database accession PX488893) shared 100% identity with A. nymphii isolated from the intestinal tract of a cockatiel (Nymphicus hollandicus) from Japan in 2015 (GenBank database accession LC057210.1) based on PCR and sequence analysis of an 815 bp segment of the 18S rRNA gene. This report describes the accidental A. nymphii infection, which caused severe gastrointestinal impaction and hepatic migration in a domestic pigeon. Full article
