The novelty of influenza epidemics of 1972-1973 in Leningrad and other towns of the Soviet Union was due to changes in the antigenic profile of influenza viruses neuraminidase which was found to be closely related to that of A/Victoria/35/72 virus according to the results of neuraminidase activity inhbition test. The epidemic influenza A virus strains isolated in 1972-1973 were also found to be sensitive to thermostable inhibitors of mouse serum which was not typical for the Hong Kong group of viruses.
1972 - 1973年列宁格勒及苏联其他城镇流感疫情的新奇之处在于流感病毒神经氨酸酶抗原特性的变化。根据神经氨酸酶活性抑制试验结果，发现其与A/维多利亚/35/72病毒的抗原特性密切相关。1972 - 1973年分离出的甲型流行性感冒病毒株也被发现对小鼠血清的耐热抑制剂敏感，而这对于香港病毒组来说并不典型。
