Publication Metadata only Prevalence of Candida species in Turkish children: relationship between dietary intake and carriage(PERGAMON-ELSEVIER SCIENCE LTD, 2005) AKYÜZ, SERAP HATİCE; Kadir, T; Uygun, B; Akyuz, SIn this study, the prevalence and intensity of Candida species were evaluated in 300 healthy Turkish children aged between 0 and 12 years. The candidal carriage in 26 children who were fed only with breast milk and 38 children who were fed with both breast milk and bottle milk or other fluids was also examined. Oral samples cultured for fungal growth and Candida species were identified using germ tube test, chlamydospore formation test and API 20C AUX system. The results demonstrated that the prevalence of oral candidal carriage in 300 healthy children was 26.3%. Candida albicans was the most frequently isolated yeast (84.8% of the isolates). The other yeasts were identified as Candida parapsilosis, Candida krusei, Candida kefyr, Candida famata, and Candida tropicalis. It was also observed that the frequency of carriage varied as a function of age. The prevalence of carriage in children who were fed with both breast milk and bottle milk or other fluids was 18.5%, while in children fed only with breast milk was 0%. This finding supports previously reported observations that there may be intrinsic differences in oral carriage of Candida species between different ages and populations and type of dietary intake may affect frequency of carriage.

This may result in the exposure of the FRCs which may affect the adherence of microorganisms. This study evaluated the adhesion of Candida albicans to a denture base resin (N = 48), reinforced with E-glass FRCs with different architectures [unidirectional (n = 16) and woven (n = 16)], when exposed to either saliva or distilled water. Materials and methods: Specimens without FRC reinforcement served as control (n = 16). After fiber surfaces were exposed, half of the specimens (n = 8/per group) were treated with saliva, the other half was stored in distilled water prior to C. albicans adhesion. The adhered microorganisms were counted under an optical microscope and the data were analyzed. Results: When exposed to distilled water or saliva, specimens with unidirectional (5403.4 cells/cm(2) and 5013.4 cells/cm(2), respectively) (p = 0.202), woven fibers (4053.5 cells/cm(2) and 3726.6 cells/cm(2), respectively) (p = 0.283) and specimens without fibers (2250 cells/cm(2) and 2006.8 cells/cm(2), respectively) (p = 0.423) showed C. albicans adhesion, being not significant. In general, all the specimens exposed to saliva showed 3582.2 cells/cm(2) C. albicans adhesion, while specimens exposed to distilled water showed 3902 cells/cm(2) C. albicans adhesion, yet being not significant (p = 0.436). Regarding fiber type, C. albicans adhesion was significantly affected by the exposed FRC architecture with more favorable results for woven fibers (p < 0.001). Conclusion: Polymethylmethacrylate without FRCs collected less C. albicans. The presence of saliva seems to reduce the adhesion.Publication Metadata only Distribution and phospholipase activity of Candida species in different denture stomatitis types(SPRINGER, 2006) KADİR, TANJU; Gumru, Birsay; Kadir, Tanju; Uygun-Can, Banu; Ozbayrak, SemihThe aim of this study was to evaluate the correlation between frequency and phospholipase activity of Candida species and denture stomatitis according to Newton's classification. Seventy-five complete denture wearers were evaluated for the presence of yeasts on the palatal mucosa by culture method. In addition, the number of yeast isolates producing phospholipase and amount of this enzyme were determined using egg yolk agar plate method. According to Newton's classification, 25 denture wearers were with healthy palatal mucosa while 50 were with any types of denture stomatitis. The frequency of yeasts was linked to whether subjects had Type II or Type III, but not Type I denture stomatitis. Candida albicans was the most frequently isolated species in denture wearers with and without clinical signs of denture stomatitis and it was the only species produced phospholipase. Although the amount of phospholipase produced by the C. albicans isolates from denture wearers in control and Type II and III DS groups was not significantly different, there was statistically significant difference in the number of C. albicans isolates producing phospholipase between patients with and without clinical signs of DS.
