Complexity of Diarrhea‐Associated Viruses in Stunted Pigs Identified by Viral Metagenomics

Transboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
Viral diarrhea poses a severe threat to the health and growth of piglets, especially when caused by co‐infection with multiple diarrhea‐associated viruses. In this study anal swabs were collected from pigs older than 3 months from a farm in Gansu province, China, and subjected to viral metagenomic analysis.

An asymptotical method to estimate the parameters of a deteriorating system under condition-based maintenance [PDF]

, 2013
In this paper, we develop a new method to estimate the parameters of a deteriorating system under perfect condition-based maintenance. This method is based on the asymptotical behavior of the system, which is studied by using the renewal process theory ...

Rapid and visual detection of porcine deltacoronavirus by recombinase polymerase amplification combined with a lateral flow dipstick

BMC Veterinary Research, 2020
Background Porcine Deltacoronavirus (PDCoV) is a newly emerging Coronavirus that was first identified in 2012 in Hong Kong, China. Since then, PDCoV has subsequently been reported worldwide, causing a high number of neonatal piglet deaths and significant

Differential Susceptibility to Porcine Deltacoronavirus: Ducks Show Greater Vulnerability Than Geese

Transboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
Porcine deltacoronavirus (PDCoV), an enteropathogenic coronavirus belonging to the Deltacoronavirus genus, is globally distributed and represents a significant viral enteric disease in pigs. It primarily causes severe diarrhea in pigs, especially in newborn piglets, with high fatality rates, resulting in substantial losses to the pig farming industry ...

Prevalence, Genetics, and Evolution of Porcine Astrovirus 3 in China

Transboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
Porcine astrovirus 3 (PAstV3) is an emerging virus associated with porcine polioencephalomyelitis outbreaks and is frequently detected in the feces of both healthy and diarrheal pigs. Despite its significance, the prevalence, genetic characteristics, and evolutionary features of PAstV3 in China remain poorly understood.

Preparation and Epitope Identification of Monoclonal Antibodies against the NS6 Protein of Porcine Deltacoronavirus (PDCoV)

International Journal of Molecular Sciences
Porcine deltacoronavirus (PDCoV) is an emerging enteric pathogen that causes substantial economic losses in the swine industry worldwide. The PDCoV NS6 protein is an accessory protein that plays a pivotal role in the viral life cycle and immune evasion. However, the functions of NS6 and its role in PDCoV pathogenesis remain largely unknown.

Design of Mucosal Vaccines Against Swine Enteric Coronaviruses: From Antigen Delivery to Immune Activation

Transboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
Swine enteric coronaviruses (SeCoVs) cause acute enteritis and high mortality in neonatal piglets, posing a significant threat to the swine industry. Injectable vaccines often fail to induce effective mucosal immunity, and their efficacy is further compromised by maternally derived antibodies.

Epitope screening and self-assembled nanovaccine molecule design of PDCoV-S protein based on immunoinformatics

Frontiers in Microbiology
Based on the whole virus or spike protein of pigs, δ coronavirus (PDCoV) as an immunogen may have unrelated antigenic epitope interference. Therefore, it is essential for screening and identifying advantageous protective antigen epitopes. In addition, immunoinformatic tools are described as an important aid in determining protective antigenic epitopes.
