H5N1 Avian Influenza Panzootic Targets Antarctic Skuas: A Growing Wildlife Health Crisis
The panzootic spread of highly pathogenic avian influenza A (H5N1) is expanding beyond its traditional ranges, now reaching remote Antarctic seabird colonies and causing alarming mortality among skuas. While H5N1 has long been associated with outbreaks in birds and mammals across continents, recent reports highlight the vulnerability of Antarctic wildlife to this high‑pathogenic virus, underscoring…

Asexual Giardia lineage spreads across hosts: new insights
Overview: A new chapter in Giardia’s history An asexual lineage of Giardia, the microscopic parasite responsible for diarrhea worldwide, appears to be spreading across different animal hosts more than researchers previously recognized. A WEHI-led team in Australia has uncovered evidence that this particular Giardia lineage can infect a broader range of species, a finding with…
