ANTIMICROBIAL ACTIVITY OF VEGETAL SPECIES OF CORDOBA AGAINST MICROORGANISMS RISPONSIBLE OF HUMAN PATOLOGIES Casero, C; Gallucci, N; Oliva, M; Grosso, M; Demo, M. Fac C.Ex.F-QyN.UNRC. ccasero@exa.unrc.edu.ar Introduction: Medicinal plants have constituted a source for diseases treatment in primary health care in developing countries and in countries where conventional medicine is predominant. Folk medicine in Argentina employs many herbs to treat diseases. Aims: To study the antimicrobial activity (AA) of plant extracts against human pathogen strains. Materials and methods: Extracts of A.satureioides, V.encelioides, C.pallida, C.album, A.aroma, X.cavanillesii, C.bonariensis, A.annua, A.cotula, B.articulata, C.vulgare, L.turbinata, B.pilosa, B.catharticus were obtained by maceration in hexane (HE), dichloromethane(DE), methanol-H2O(ME). AA and minimum inhibitory concentration(MIC) was performed by the agar diffusion method on: A.baumany, S.aureus, E.coli, P.vulgaris, E.amnigenus, K.pneumoniae, Salmonella sp., P.aeruginosa, P.alcalifaciens, A.radiobacter, E.faecium, E.faecali, B.cereus, C.albicans. Results and discussion: X.cavanillesii, A.cotula, C.bonariensis, L.turbinata showed some AA. HE and DE of A.satureioides revealed a wide range of AA. The MIC from flowers HE was of 0.56mg/ml for E.amnigenus and S.aureus and 2.5mg/ml for P.aeruginosa. The MIC of leaves HE was 1.25mg/ml and 0.56mg/ml for E.amnigenus and S.aureus respectively. Conclusion: emergence of resistant microorganisms to antibiotics needs new therapeutic options being A.satureioides a promising alternative.
