THE ANTIFUNGAL EFFECT OF DIFFERENT CONCENTRATIONS OF OIL SOLUTIONS OF CYMBOPOGON CITRATES AND COCOS NUCIFERA AGAINST CANDIDA ALBICANS The identified funguson people who suffer from diaper rash was opportunistic Candida albicans which commonly occurs as a harmless commensal on human micro flora but occasionally causes secondary skin infections -if not treated-especially in immunocompromised C.citratus oil solutions on Candida albicans was investigated within a comparison to protect people suffering from diaper rash from possible C.albicans infections by using new and natural supportive care methods from C.nucifera and C.citratus was aimed. During the investigation, Candida albicans sample was taken from Atatürk University Department of Microbiology, C.nucifera and C.citratus oils were obtained commercially and then disc diffusion method was applied with seven different concentrations of both oil solutions on inoculated nutrient agar with 10 -4 CFU ml -1 C.albicans and incubated at 37ºC for 48 hours. The data results showed that oil solutions of C.citratus and C.nucifera -diluted by DMSO- BIOLOGY DEPARTMENT patients. Although antifungal creams widely use important biochemicals in order to treat or prevent the infections; due to increasing development of antifungal resistance and the appearance of undesirable side effects, antifungal activities have been emphasized more frequently in a wide range of essential oils and natural products in an attempt to discover new antiinfective agents.Also, recent studies showed that gram positive strain of C.albicans gained resistance against frequently used fluconazole antifungal agents (Marchaim et al, 2012). Thus, in this experiment the antifungal effect of different concentrations (1%,2%,4%,8%,16%,32%,64%) of C.nucifera and have antifungal activity against C.albicans and for each seven concentration C.citratus demonstrated higher inhibition zone diameter in average against C.albicans such as respectively 6.1-8.3 mm for 1%; 6.6-8.3mm for 2%; 7.5-9.5mm for 4%; 8.6-10.1mm for 8%; 9.3-11.8mm for 16%; 10.3-13.9mm for 32%; 11.3-14.7mm for 64%.In that point, the difference between antifungal activities of C.nucifera and C.citratus were supported with One-way ANOVA test in SPSS 21.0 program since p<0.5.
