Using a pan-astrovirus reverse transcription-PCR assay, a great diversity of novel avastroviruses was detected from wild bird and poultry samples. Two groups of astroviruses detected from wild birds are genetically related or highly similar to previously known viruses in poultry. Most interestingly, a novel group of astroviruses was detected in wild aquatic birds. Our results also reveal that different groups of astroviruses might have difference host ranges. This study has expanded our understanding regarding avastrovirus ecology.

Gut microbiota are fundamental for healthy animal function, but the evidence that host function can be predicted from microbiota taxonomy remains equivocal, and natural populations remain understudied compared to laboratory animals. Paired analyses of covariation in microbiota and host parameters are powerful approaches to characterise host-microbiome relationships mechanistically, especially in wild populations of animals that are also lab models, enabling insight into the ecological basis of host function at molecular and cellular levels. The fruitfly is a preeminent model organism, amenable to field investigation by 'omic analyses.

Background: B-cell specific Moloney MLV insertion site-1 (Bmi-1) belongs to the polycomb group (PcG) gene and is a transcriptional suppressor to maintain appropriate gene expression patterns during development. To investigate whether the Bmi-1 gene has a corrective effect on bone senescence induced in Bmi-1 mice through regulating the bone microenvironment.
Methods: Littermate heterozygous male and female mice (Bmi-1) were used in this study.
Between 21 September and 6 December 2024, 657 highly pathogenic avian influenza (HPAI) A(H5N1) and A(H5N5) virus detections were reported in domestic (341) and wild (316) birds across 27 countries in Europe. Many HPAI outbreaks in domestic birds were clustered in areas with high poultry density and characterised by secondary farm-to-farm spread. Waterfowl, particularly the mute swan, were primarily affected during this reporting period, with HPAI virus detections focused on south-eastern Europe.

Despite global initiatives to eliminate dog-mediated human rabies by 2030, the Arabian Peninsula faces challenges due to insufficient data. This review addresses the current rabies situation and knowledge gaps in the region and proposes One Health interventions. Employing a mixed-method approach combining scoping and systematic review, the study commenced with a Delphi discussion to identify knowledge gaps and set objectives.

Background: African buffalo (Syncerus caffer) is a significant reservoir host for many zoonotic and parasitic infections in Africa. These include a range of viruses and pathogenic bacteria, such as tick-borne rickettsial organisms. Despite the considerations of mammalian blood as a sterile environment, blood microbiome sequencing could become crucial for agnostic biosurveillance.
