The deadly H5 variant of avian influenza has been detected in a bird that washed up on a remote beach in Western Australia's south, the first time the disease has been found in Australia.

Deformed Wing Virus type A (DWV-A) is one of the primary threats to honeybees (Apis mellifera), significantly impacting their nervous system physiology and behavior. While its neurotropic nature is well-recognized, the temporal dynamics of the neuronal transcriptomic response following oral infection, the natural transmission route, remains poorly understood. In this study, we analyzed gene expression in the heads of worker bees orally inoculated with DWV-A over a 16-day time course (1, 4, 7, 10, 13, and 16 days post-inoculation). RNA-seq analysis at day 10 identified 147 differentially expressed genes associated with different biological processes that are critical to the organism, including cellular metabolism and neuronal activity. RT-qPCR validation revealed a persistent downregulation of key genes related to glutamatergic system (eaat-2, neto, and kainate) and sensory perception-related genes in the antennae. Notably, the simultaneous co-expression of nurse-associated and forager-associated marker genes suggests that DWV-A infection induces an asynchrony in behavioral maturation. Our findings demonstrate that DWV-A disrupts neuronal homeostasis and peripheral sensory perception in a tissue-specific and time-dependent manner, providing a molecular framework to understand the behavioral impairment and the loss of coordination at the colony level.

The minister for agriculture, Julie Collins, confirms case of H5N1 bird flu in Western Australia, with another suspected

The Ebola epidemic in eastern Democratic Republic of Congo (DRC) continues to cause serious concern.

LOS ANGELES – In early 2022, around the time the Omicron variant started driving a new surge in COVID-19 cases, researchers at James DeGregori’s University of Colorado Anschutz lab noticed something unusual: When lab mice with dormant breast cancer cells were infected with either influenza or SARS-CoV-2, the animals were significantly more likely to develop aggressive lung tumors.

"Whilst disappointing, this is not unexpected, given the global spread of the H5 bird flu," Collins told reporters in Canberra.
