Immunological properties of selected strains of Trichophyton genus.

ABSTRACT

The investigations demonstrated that the strains under study, either virulent or in the form of inactivated vaccines, induced a delayed type allergy. The response depended upon the affiliation to a determined species and individual properties of a strain. The strain T. mentagrophytes 1 displayed the highest biological activity, since it was a good inducer of allergy and a manufacturer of active trichophytin in tests performed both in vivo and in vitro.
