title: Age related variations of serum concentrations of normally occurring IgG antibodies to Clostridium perfringens.
abstract: In studies using indirect immunofluorescence IgG antibodies to Clostridium perfringens were found in sera from healthy adults. Sera from 236 healthy children were examined. The normally occurring IgG antibodies to C perfringens were found to have an age related variation. Preliminary data suggest that they are not correlated to C perfringens alpha toxin. The antigen(s) against which the antibodies are directed is/are probably part of the cell wall, but its/their exact nature is not known.
