Hybridization of single-stranded RNA from virions of human enteroviruses with denatured double-stranded RNA from infected cells indicates that a minimum of about 5% of the genome is shared by these viruses. Polynucleotide sequence relationships, furthermore, are consistent with the biologic classification into polioviruses, coxsackieviruses groups A and B, and echoviruses. In general, about 30 to 50% of the nucleotide sequences are shared by different serotypes of virus within each of these major groups, whereas among different groups less than 20% homology is observed. Coxsackievirus B4 appears to be more closely related to echoviruses than to group A coxsackieviruses, whereas polioviruses are only distantly related to any of the other agents.
人肠道病毒病毒粒子的单链RNA与受感染细胞的变性双链RNA杂交表明,这些病毒至少有大约5%的基因组是相同的。此外,多核苷酸序列关系与脊髓灰质炎病毒、A组和B组柯萨奇病毒以及埃可病毒的生物学分类一致。一般来说,在这些主要病毒组中的每一组内,不同血清型病毒共享约30%至50%的核苷酸序列,而在不同组之间,观察到的同源性不到20%。柯萨奇病毒B4似乎与埃可病毒的关系比与A组柯萨奇病毒的关系更密切,而脊髓灰质炎病毒与其他任何一种病原体的关系都很疏远。
