High pathogenicity avian influenza A (H5N1) clade 2.3.4.4b virus infection in a captive Tibetan black bear (Ursus thibetanus): investigations based on paraffin-embedded tissues, France, 2022

Pierre Bessière, Nicolas Gaide, Guillaume Croville…·Guillaume Le Loc’h

The paper characterizes H5N1 virus infection in a Tibetan black bear using histopathology and sequencing of paraffin-embedded tissues, finding high genetic similarity to a gull strain and evidence of mammalian adaptation.
