In order to elucidate the antigenic structure of poliovirus, the reactivity of antibody produced with H antigenic particles of Mahoney strain (polio type 1) was investigated. Injection of H particles of Mahoney strain into rabbits yielded neutralizing antibody as well as CF‐N and CF‐H antibodies. This result coincided with the report by Hinuma and coworkers. Neutralization tests with inhibitor resistant Mahoney mutants revealed that the neutralizing antibody produced with H particles was of HN31 type, one of the five different kinds of polio neutralizing antibodies reported previously (14). Absorption experiments with H particles on different neutralizing antibodies and analysis of antibody eluted by acid dissociation from antiserum‐treated H particles also showed that the HN31 type antibody specifically combined with H particles of Mahoney strain. Since the H particle of poliovirus is known to be deficient in VP4, these results seems to indicate that the HN31 type antibody reacts with a structural part(s) of poliovirus other than VP4.
