Monoclonal antibody panels developed to differentiate vaccine-derived and wild-type strains of polio-viruses were applied to isolates from cases of paralytic poliomyelitis, non-paralytic poliomyelitis, and healthy excreters of poliovirus from Poland. All isolates from poliomyelitis cases were shown to be vaccine-derived, as were most other strains. However, two strains associated with meningitis had wild-type antigenic phenotypes and, as shown by partial genomic sequencing, wild-type genotypes. Correlation of laboratory and epidemiological data suggested that residual cases of paralytic poliomyelitis in Poland between 1981 and 1990 were vaccine-related. Study of the non-paralytic cases, however, helped identify the circulation of endemic wild-type viruses in a well-vaccinated community.
为区分脊髓灰质炎病毒的疫苗衍生株和野生型株而研发的单克隆抗体组,被应用于来自波兰麻痹性脊髓灰质炎病例、非麻痹性脊髓灰质炎病例以及脊髓灰质炎病毒健康排泄者的分离株。所有脊髓灰质炎病例的分离株均显示为疫苗衍生株,其他大多数毒株也是如此。然而,两株与脑膜炎相关的毒株具有野生型抗原表型,并且如部分基因组测序所示,具有野生型基因型。实验室数据与流行病学数据的相关性表明,1981年至1990年间波兰残留的麻痹性脊髓灰质炎病例与疫苗有关。然而,对非麻痹性病例的研究有助于确定在一个疫苗接种良好的社区中地方性野生型病毒的传播情况。
