The #avian and #human #influenza A virus #receptors #sialic acid (SA)-α2,3 and SA-α2,6 are widely expressed in the #bovine #mammary #gland, BioRxIV, https://www.biorxiv.org/content/10.1101/2024.05.03.592326v1?rss=1

IAVs isolated from chickens generally bind more tightly to SA-α2,3-Gal-β1,4 (chicken receptor), whereas IAVs isolated from duck to SA-α2,3-Gal-β1,3 (duck receptor). We found all receptors were expressed, to a different degree, in the mammary gland, respiratory tract, and cerebrum of beef and/or dairy cattle.
