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

Abstract
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, [...] Read more.
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
