Article Synopsis
- Infectious bursal disease (IBD) is a viral disease affecting poultry, significantly impacting Nigeria's economy and food security, with outbreaks occurring even in vaccinated flocks.
- Research on four near-complete IBDV genomes revealed specific conserved amino acid markers associated with very virulent strains and showed that these viruses cluster in a newly defined A3B5 group.
- Unique mutations in the IBDV genomes indicate reassortant viruses, which could explain vaccination failures in Nigeria, highlighting the need for ongoing genome monitoring and effective vaccination strategies.
The first detection of a Highly Pathogenic Avian Influenza (HPAI) H5N8 virus in Bulgaria dates back to December 2016. Since then, many outbreaks caused by HPAI H5 viruses from clade 2.3.

To determine their phenotypic effects, we studied recombinant variants of A/Hong Kong/1/1968 virus containing either human-type or avian-type amino acids in the corresponding positions of HA. The precursor HA displayed receptor binding profile and high conformational stability typical for duck IAVs.

This study aims to evaluate the antioxidant capacity and prooxidant effects of juçara pulp fermented with or before and after spray-drying with maltodextrin, gum arabic or gelatin and stored at 25 °C for 90 days. The antioxidant capacity was assessed by measuring the ability to scavenge reactive oxygen species (ROS) in the neutrophil respiratory burst and free radical 2,2-diphenyl-1-picryl-hydrazyl (DPPH), and by determining the total phenolic content.

Subsequent to the H9N2 outbreak, the causal agent was successfully isolated from chicken flocks with high morbidity and mortality rates, propagated on embryonated eggs, and fully sequenced. The phylogenetic analysis suggested that the Moroccan isolate could have derived from the Middle East isolate A/chicken/Dubai/D2506.
