Justificación y Objetivos: El género Cymbopogon ha despertado interés debido a sus compuestos bioactivos con potencial antifúngico y antimicrobiano. Este estudio evaluó la actividad antifúngica in vitro del aceite esencial de Cymbopogon flexuosus libre y nanoemulsionado contra cepas estándar ATCC de Candida spp. Métodos:
En el ensayo se utilizaron las cepas Candida albicans, Candida tropicalis, Candida krusei y Candida glabratacomparadas con un control positivo (Fluconazol y Anfotericina B) y un control negativo (agua destilada + Tween 80 al 2%). Se empleó la técnica de difusión en agar. Tras el tratamiento, los ensayos fueron incubados a 36 °C durante 48 horas y realizados con seis repeticiones. Resultados: En el ensayo se observó actividad antifúngica para todas las cepas ATCC evaluadas. El aceite libre en concentraciones del 10%, 15% y 70% mostró actividad similar al control positivo para Candida tropicalis. La concentración del 5% del aceite nanoemulsionado presentó resultados comparables al control positivo para Candida glabrata. Conclusión: Entre las especies analizadas, Candida albicans demostró ser la más sensible en todas las concentraciones, mientras que Candida krusei fue la cepa más resistente al uso del aceite esencial. Se requieren nuevos estudios, de carácter toxicológico y clínico, para complementar nuestros hallazgos.
