In order to define poliovirus (PV) neurovirulence at the molecular level, we comparatively analyze the primary amino acid sequence of Mahoney, a neurovirulent PV strain, versus (i) Sabin, an attenuated PV strain, and (ii) IS1, a PV isolate obtained in temporal association to a paralysis event from a polio vaccinated subject. We identify and describe 12 pentapeptides that, originally present in the Mahoney sequence, are changed in the non-neurovirulent Sabin strain, and, successively, restored in IS1 strain.

Abstract
In order to define poliovirus (PV) neurovirulence at the molecular level, we comparatively analyze the primary amino acid sequence of Mahoney, a neurovirulent PV strain, versus (i) Sabin, an attenuated PV strain, and (ii) IS1, a PV isolate obtained in temporal association to a paralysis event from a polio vaccinated subject. We identify and describe 12 pentapeptides that, originally present in the Mahoney sequence, are changed in the non-neurovirulent Sabin strain, and, successively, restored in IS1 strain.File in questo prodotto:
