| Abstract: | ![]()
Qualitative immunological differences exist between early passage strains or so called human strains of the virus of poliomyelitis. These differences show a relationship to the epidemic source of the virus and are exemplified in this study by 4 strains isolated in different years during an eastern and western epidemic of poliomyelitis. |
