Association with sludge solids did not allow poliovirus to enter cells other than through the normal receptor-mediated route. This implies that the infectivities of sludge-encapsulated virions are masked until their exposure permits binding to cell surface receptors.
与污泥固体物结合后，脊髓灰质炎病毒无法通过正常的受体介导途径以外的方式进入细胞。这意味着被污泥包裹的病毒粒子的感染性被掩盖，直到其暴露后才能与细胞表面受体结合。
