ABSTRACT

Introduction:

considering the emergence of resistant species of albicans and non-albicans Candida to agents therapeutically available as a result of the increased number of immunocompromised population and of the increasingly frequent use of prophylaxis and empirical treatment with antifungals, it's verified that there is a clear and emerging need to introduce new antimicrobials agents in the therapeutic arsenal. The purpose of this study was to evaluate the antifungal activity of essential oil of Cinnamomum zeylanicum Blume alone and combined with Nystatin on strains of C. tropicalis and C. krusei.

Methods:

this was an experimental research in laboratory. It was determined the Minimum Inhibitory Concentration, using the microdilution method, as well as the Fractional Inhibitory Concentration to determine the possible synergistic effects of the association. Strains of C. tropicalis ATCC 40147 and C. krusei ATCC 40042 were used in the tests. When assessed separately, C. zeylanicum essential oil and Nystatin presented Minimum Inhibitory Concentration of 312,5 µg/mL and 64 µg/mL, respectively, on both tested strains.

Results:

When combined, were found Minimum Inhibitory Concentration of 39 µg/mL and 32 µg/mL for the essential oil and for Nystatin, respectively. The Fractional Inhibitory Concentration value was 0,6024 for both tested strains, indicating additivity of the inhibitory effect on fungal growth.

Conclusions:

the results indicate that C. zeylanicum essential oil has antifungal activity against the strains of non-albicans Candida evaluated and that its association with Nystatin potentiates this effect(AU)
RESUMEN

Introducción:

es necesaria la introducción de nuevos agentes antimicrobianos por el surgimiento de especies de Candida albicans y no albicans resistentes a los agentes terapéuticos disponibles .El objetivo del estudio fue evaluar la actividad antifúngica del aceite esencial de Cinnamomum zeylanicum Blume aislado y asociado con nistatina sobre cepas Candida tropicalis y Candida krusei.

Métodos:

se realizó una investigación experimental de laboratorio. La concentración mínima inhibitoria fue determinada utilizando el método de microdilución, y la concentración inhibitoria fraccionada se usó para determinar los posibles efectos sinérgicos de la asociación. Para las pruebas fueron utilizadas las cepas de C. tropicalis ATCC 40147 y C. krusei ATCC 40042. Se usaron el aceite esencial de C. zeylanicum y nistatina. Cuando fueron evaluados por separado presentaron la concentración mínima inhibitoria de 312,5 µg/mL y de 64 µg/mL, respectivamente, sobre ambas cepas ensayadas.

Resultados:

una vez asociados, la concentración mínima inhibitoria fue de 39 µg/mL para el aceite esencial y de 32 µg/mL para la nistatina. El valor de la concentración inhibitoria fraccionada para ambas cepas probadas fue de 0,6024, lo que indica adicción del efecto inhibidor sobre el crecimiento de hongos.

Conclusiones:

los resultados indican que el aceite esencial de C. zeylanicum tiene actividad antifúngica frente a las cepas de Candida no albicans y que la asociación del mismo con la nistatina promueve la potenciación de este efecto(AU)
