Article Abstract
Chicken infectious anemia virus (CIAV) is the pathogen of chicken infectious anemia. Currently, due to the lack of effective diagnostics technology and prevention approach, CIAV has spread globally and caused huge economic losses to poultry industry. In this study, a novel peptide-based ELISA (pELISA) for efficient detection of antibody against CIAV was developed. The peptide (25CRLRRRYKFRHRRRQRYRRRAF45) used in pELISA was highly conserved in VP1 protein of different CIAV isolates. The specificity and reproducibility showed that the pELISA only reacted with sera against CIAV, not with sera against other pathogens tested, and the CV of the intra-/inter-assay of the pELISA was 6.8 to 9.22%. Moreover, the comparison assay using 56 clinical samples showed that the positive rate of the pELISA and the commercial ELISA kit (IDEXX) was 85.7 and 80.4%, respectively. The pELISA generated here provides a rapid and efficient serological detection method for diagnosis of CIAV infection and evaluation of the efficacy of CIAV vaccination.

Aims: This study aims to investigate the genomic profile of a multidrug-resistant Escherichia coli strain, 160-11H1, co-carrying an extended-spectrum β-lactamase (ESBL) and the plasmid-mediated mobile colistin resistance gene, mcr-5.
Methods And Results: The entire genome of the strain was sequenced using Illumina MiSeq and Oxford Nanopore platforms, and de novo assembly was performed using Unicycler. The genome size was 5 031,330 bp and comprised 5 140 coding sequences.

Infectious bursal disease (IBD), a highly contagious viral disease in young chickens, poses significant economic losses due to high mortality and immunosuppression. While IBD virus (IBDV) virulence is influenced by multiple genes, whole-genome sequencing (WGS) of IBDV is crucial for defining the strain pathotype and clinical profile. Flinders Technology Associates (FTA) cards are convenient for field sample collection, but their filter paper matrix can hinder nucleic acid recovery, impacting sequencing efficiency.

Influenza viruses can be aerosolized when slaughtering infected chickens, which increases the risk of zoonotic transmission. We conducted pilot experiments to measure the concentrations of airborne particles <2.5 μm during slaughtering and defeathering of chickens to help identify methods that can minimize workers' exposure to potentially hazardous aerosol particles.

Infectious bursal disease virus (IBDV) is a highly contagious, economically relevant immunosuppressive pathogen of chickens. Despite belonging to a single serotype, virulent IBDVs display a remarkable heterogeneity in genetic and functional features. Traditionally, strains are categorized into classical, variant and very virulent viruses, but many atypical IBDVs have been recently identified.

In this study, we identified a new chicken-specific protein, named chicken interferon-related antiviral protein (chIRAP) after sequence analysis and comparison, which inhibited the proliferation of various viruses including influenza A virus (IAV) and Newcastle Disease Virus (NDV) in vitro, and chicken embryos with high expression of chIRAP reduced IAV infection. Mass spectrometry analysis of chIRAP interacting proteins and screening of interacting proteins affecting the function of chIRAP revealed that the deletion of endogenous chicken peroxiredoxin 1 (chPRDX1) significantly reduced the antiviral effect of chIRAP. In order to clarify the functional site of chPRDX1 affecting the antiviral effect of chIRAP, we constructed the point mutants of chPRDX1 based on the results of molecular docking (D79A, T90A, K93A, Q94A, R110A, R123A), and screened the sites affecting the antiviral effects of chIRAP by knockdown of endogenous chPRDX1 combined with the overexpression mutant strategy, the results showed that the mutations in the sites affected the antiviral effects of chIRAP to different degrees, with D79A being the most significant, and the D79A mutation of chPRDX1 reduces the ability of chPRDX1 to regulate reactive oxygen species (ROS).
