Background and Purpose
Oral candidiasis has become a growing problem in hospitals worldwide, and the development of antifungal drug resistance in Candida species constitutes a serious concern. This study aimed to evaluate the in vitro efficacy of nystatin, and micafungin with chlorhexidine against fluconazole-resistant and fluconazole-sensitive Candida albicans (C. albicans) isolates.
Materials and MethodsIn this experimental-laboratory study, a total of 20fluconazole-resistant (n=10) and fluconazole-susceptible (n=10) C. albicans strains were obtained from the reference culture collection of the Invasive Fungi Research Center in Mazandaran University of Medical Sciences, Sari, Iran. In vitro combination of nystatin and micafungin with chlorhexidine was performed using a microdilution checkerboar method based on the Clinical and Laboratory Standards Institute guideline.
ResultsMicafungin had the highest antifungal activity against C. albicans susceptible and resistant strains, with a Geometric mean of (GM) =0.008µg/ml and GM=0.008µg/ml, followed by nystatin with GM=0.06µg/ml and GM=0.042µg/ml and chlorhexidine with GM=0.25µg/ml and GM=0.165µg/ml against C. albicans resistant and sensitive strains, respectively. The interaction of micafungin and nystatin withchlorhexidine showed a synergistic interaction against most C. albicans strains. Inaddition, no antagonistic interaction was observed between micafungin, nystatin, and chlorhexidine against C. albicans strains.
ConclusionThe synergistic interaction of micafungin with chlorhexidine against azoleresistant C. albicans suggests an alternative approach to overcome antifungal drug resistance. However, further studies are needed for in vivo evaluation. Candida albicans, Chlorhexidine, Combination, Fluconazole, Micafungin,Nystatin
