title: [Influence of the cryopreservation at nitrogen temperature on the vaccinic ability of the "PF" strain of Trypanosoma cruzi (author's transl)].
abstract: The cryopeservation of the "PF" strain of T. cruzi at -196 degree C has not changed its effectiveness in protecting mice against a posterior infection with a virulent Trypanosoma cruzi strain. The cryopeservation technique utilized seems to be efficient and of practical and rapid examination.
