Inoculation with highly pathogenic avian influenza H5N1 genotype D1.1 in naïve dairy cows and dairy cows previously exposed to genotype B3.13

2025-12-30

Abstract excerpt

<title>Abstract</title> <p>USDA confirmed by whole genome sequence the first detection of HPAI H5N1 clade 2.3.4.4b genotype D1.1 in dairy cattle. While genotype D1.1 has been the dominant strain circulating in migratory birds in North America, the Nevada cases represent the first detection of a genotype other than B3.13 in cattle and the second known spillover event from wild birds into lactating dairy cattle. D1...
