Background & Objectives: Candida Albicans is a fungus that frequently infects diabetic patients. Because it is very common infection in diabetics, we tried to determine the prevalence of infection and the asymptomatic carriers and show factors like age, sex, duration of diabetes and quality of disease control that  probably  have effect on infection.
Methods: In this study 200 diabetic patients were chosen randomly and blood samples were taken for FBS and HbA1C and then skin smears were performed from body folds (Axillaries groin interdigital folds) and probable lesions. The skin samples were cultured in Chrom-Agar medium. Then the gathered data were analyzed.
Results: Overall, from 200 patients, there were 180 (90%) negative culture and 20 (10%) positive cultures. Candidial infection in men and older patients were relatively higher than others. Candida infection in poor controlled diabetes was considerably higher .Infection in type-1 diabetes was more than type-2 diabetes. There was no correlation between duration of diabetes and prevalence of infection.
Conclusion: Candida infection is more common in diabetic patients with poor control, male and older ones.

  Background & objectives: In recent decades, nanotechnology has been developing in medical field, and most of the nanoparticles are highly valuable in hygienic care. Vulvovaginitis is an infectious disease giving rise to problem in genital tract and Candida albicans is the main cause of Vulvovaginitis.

  Methods: In this study, laboratory effect of gold nanoparticles has been investigated on Candida albicans isolates obtained from patients with Vulvovaginitis. Candida spp. isolates were obtained from 200 patients referring to medical diagnostic laboratory in Isfahan city during 2013, and identified using mycological methods including germ tube, clamydoconidia formation, and culturing on chrom agar media. Antifungal effect of gold nanoparticles was evaluated in concentration of 100, 50, 25, and 12.5 ppm on Candida isolates using well diffusion and microdilution methods. Fluconazole was used as a positive control and results were analyzed by SPSS15 software using Mann-Whitney, Kruskal-Wallis and average differences analysis tests.

  Results: The most averages of clear zone diameter for gold nanoparticle were 18, 15, 12 millimeter, respectively. Minimum inhibitory and fungicidal
concentration of gold nanoparticle was determined 6.25, 12.5 ppm and for fluconazole were 50.25±19.48 and 100.50±38.96, respectively. Based on obtained results antifungal activity of gold nanoparticle was dependent to concentration.

  Conclusion: In current study, inhibitory effect of gold nanoparticles was evaluated against microorganism. Although the laboratories findings are promising, more investigation should be conducted for therapeutic standardization.
