Antibody response against strains of influenza-A virus in ferrets with basic immunity
- 18 Downloads
In Holland ferrets are offered for sale with basic antibodies against one or more sub-groups of strains of influenza-A virus. With the haemagglutination inhibition test low basic antibody titers can only be detected by neutralising the non-specific inhibitor in the ferret sera. When such a ferret is infected with a strain of a heterologous sub-group, a considerable rise in antibodies is obtained against the homologous and heterologous sub-groups. It is very probable that the same holds for human beings. Some examples are given of haemagglutination-inhibition tests with serum pairs from adults who suffered from influenza in the epidemic of the winter of 1949 in Holland from which the non-specific inhibitor had been eliminated.
