An influenzavirus of swine origin (swine/Taiwan/7310/70) antigenically closely related to the human A/Hong Kong/68 virus readily infected human volunteers. Those infected developed antihaemagglutinin and antineuraminidase antibodies to the human A/Hong Kong/68 virus as well as to the swine/Taiwan virus. The clinical reactions produced by the swine/Taiwan virus were, however, milder than those produced in volunteers infected with A/Hong Kong/68. In contrast, two other "classical" swine viruses (strains antigenically related to the prototype swine/Iowa/15/30 strain), immunologically distinct from the Hong Kong/68 virus, possessed low infectivity for man.
一种源自猪的流感病毒(猪/台湾/7310/70)在抗原性上与人类A/香港/68病毒密切相关,很容易感染人类志愿者。那些被感染的人产生了针对人类A/香港/68病毒以及猪/台湾病毒的抗血凝素和抗神经氨酸酶抗体。然而,猪/台湾病毒引起的临床反应比感染A/香港/68病毒的志愿者所产生的反应要轻。相比之下,另外两种“经典”猪病毒(与猪/爱荷华/15/30原型株抗原相关的毒株)在免疫学上与香港/68病毒不同,对人类的感染性较低。
