Abstract
The skin is the body's largest organ that hosts heterogeneous inhabitants. Until now, the diversity of the cutaneous microbiome was mainly investigated for bacteria and there is a little information about the skin fungal flora. Also among skin fungal flora, Candidais found as a main member which it's distribution is affected by sex, age, climate. In this study, differences in Candidacommunity structure associated with 9 different skin sites of 238 healthy people during 10 months, are described. These subjects were divided by age into 4 groups: infants, children, adults and geriatrics. The collected samples were examined by culture on Sabouraud Chloramphenicol Agar and CHROM-agar Candida. For precise identification of species DNA sequencing was performed where needed. The frequency of Candida species was significantly different between age groups. The most Candidaisolations were related to the elderly age group and the fewest in the infants. C. parapsilosisvirtually, was the predominant isolated species in all age groups. This study showed no statistically significant effect of the subject?s sex on Candidapopulation resident on human skin surface.
