An outbreak of influenza A (H5N1) virus was detected in dairy cows in the United States. We detected influenza A virus sialic acid -α2,3/α2,6-galactose host receptors in bovine mammary glands by lectin histochemistry. Our results provide a rationale for the high levels of H5N1 virus in milk from infected cows.

牛乳腺中的禽和人类甲型流感病毒受体

美国奶牛中发现甲型流感（H5N1）病毒爆发。我们通过凝集素组织化学检测了牛乳腺中的甲型流感病毒唾液酸-α2,3/α2,6-半乳糖宿主受体。我们的研究结果为受感染奶牛的牛奶中 H5N1 病毒含量高提供了依据。
