title: Correlation of virus polypeptide structure with attenuation of poliovirus type 1.
abstract: Several avirulent samples of poliovirus type 1 derived in the process attenuating the neurovirulent Mahoney strain show an altered virus capsid polypeptide, VP-1, on polyacrylamide gel electrophoresis of sodium dodecyl sulfate-disrupted virions.
