dc.description | The objective of this work was to evaluate the effect of the Chrysactinia mexicana A. Gray essential oil, on C. glabrata clinical isolates. The essential oil was obtained by steam entrainment of flowers, leaves and secondary branches of C. mexicana. Gas chromatography and mass spectrometry were performed to determine the oil composition. Logarithmic and stationary phase microdilution assays were performed with Saccharomyces cerevisiae and clinical isolates of C. glabrata to determine the Minimum Inhibitory Concentration (MIC) of the oil. The cultures were incubated in liquid YPD medium, for 7 h in fresh medium (logarithmic phase) or 3 h in recovering medium (stationary phase), with the oil and microdilution tests were performed. The three main oil compounds identified were piperitone (29.57%), eucalyptol (26.86%) and α-terpineol (14.65%). The MICs obtained were, a) stationary phase: S. cerevisiae (BY4741) 2.78 mg/mL and C. glabrata (CBS138), (NY66) and (AN400) 6.50 mg/mL and (NY62) 9.29 mg/mL; b) logarithmic phase: S. cerevisiae (BY4741) 3.71 mg/mL and C. glabrata (CBS138) 4.64 mg/mL, (NY66) 6.5 mg/mL, (AN400) 8.36 mg/mL, and (NY62) 18.5 mg/ mL. This work constitutes the first report of the fungicidal effect of the C. mexicana essential oil on human pathogenic fungi such as C. glabrata. | en-US |
dc.description | El objetivo del trabajo fue evaluar el efecto del aceite esencial Chrysactinia mexicana A. Gray en aislados clínicos de C. glabrata. Se obtuvo aceite esencial por arrastre de vapor de las flores, hojas y ramas secundarias de C. mexicana. Se realizó cromatografía de gases y espectrometría de masas para conocer la composición del aceite. Se hicieron ensayos de microdilución en fase logarítmica y fase estacionaria con Saccharomyces cerevisiae y aislados clínicos de C. glabrata para determinar la Concentración Mínima Inhibitoria (CMI) en presencia del aceite esencial. Los principales compuestos del aceite esencial fueron la piperitona (29.57 %), eucaliptol (26.86 %), a-terpineol (14.65 %), delta-3-careno (12.37 %) y linalool (3.56 %). Se determinaron las CMI del aceite esencial, para las cinco cepas utilizadas en las dos fases de crecimiento, siendo menor la CMI para S. cerevisiae que para los diferentes aislados clínicos de C. glabrata. El aceite esencial de C. mexicana tiene efecto fungicida en S. cerevisiae y los aislados clínicos de C. glabrata. | es-ES |
