RESUMO
Los hongos pueden causar enfermedades en humanos, especialmente en pacientes inmunosuprimidos. En este estudio, extractos de 10 plantas utilizadas en medicina popular en Argentina fueron ensayadas para estudiar la actividad antifúngica in vitro contra 4 cepas de hongos. De todas las plantas testeadas, solo 4 mostraron actividad antifúngica: Larrea divaricata Cav, Gnaphalium gaudichaudianum D.C, Baccharis trimera Less y Schinus terebenthifolius.
Fungi may cause very serious diseases in humans specially in immunosuppressed patients. In this study, extracts of 10 plants used in popular medicine in Argentine were assayed for in vitro antifungal activity against 4 fungal strains. Out of all the plants tested, Larrea divaricata Cav, Gnaphalium gaudichaudianum D.C, Baccharis trimera Less and Schinus terebenthifolius proved to have antifungal activity.

The immunoprotective capacity of four Clostridium chauvoei strains at different growth stages is reported. In all the strains tested, the cells coming from the stationary phase were those with the highest immunoprotective capacity and, depending on the strain, this protective capacity diminished or even disappeared in other phases. Protein profiles were similar in all the strains and few proteins were differentially expressed during growth as shown by SDS-PAGE. For strain 17, a local strain, a clear relationship was observed between the diminution of immunogenicity and the total loss of protective capacity of sonicated cells at late stationary phase.
