Naturally acquired antibody to H3N2 human influenza antigens was found in a yak-zebu crossbred in Nepal. Serial inoculation of a yak, negative for antibody, produced a response to A/Hong Kong/1/68 (H3N2), A/England/42/72 (H3N2), and A/Prague/1/56 (Heq1 Neq1) influenzavirus strains. Single radial diffusion tests showed that cattle and goats in West Bengal, India, and water buffaloes and cattle in Kathmandu, Nepal, also had antibodies against the H3N2 antigens. Haemagglutination-inhibition antibodies to equine influenzaviruses were not found in human, goat, cattle, chicken, and dog sera, nor were antibodies to avian viruses found in human or equine serum.
在尼泊尔的一头牦牛-瘤牛杂交种中发现了针对H3N2人流感抗原的天然获得性抗体。对抗体呈阴性的一头牦牛进行连续接种后,其对A/香港/1/68(H3N2)、A/英格兰/42/72(H3N2)和A/布拉格/1/56(Heq1 Neq1)流感病毒株产生了反应。单向辐射扩散试验表明,印度西孟加拉邦的牛和山羊以及尼泊尔加德满都的水牛和牛也具有针对H3N2抗原的抗体。在人、山羊、牛、鸡和狗的血清中未发现针对马流感病毒的血凝抑制抗体,在人或马血清中也未发现针对禽病毒的抗体。
