Abstract
In this study, microorganisms were isolated from the scalp of Korean young adult and middle ages, and their distributions in the ages were investigated. Based on 16S and 18S rDNA sequence analysis, phylogenetic trees for isolated strains were also constructed. Experimental results showed that eight different bacterial and fungal strains (Bacillus altitudinis, Malassezia furfur, Aspergillus brasiliensis, Penicillium cosmopolitanum, Cladosporium multigeniculatum, Staphylococcus epidermidis, Aspergillus sydowii, and Rhodotorula mucilaginosa) were isolated and identified from the scalps (homology: above 98%). When the distribution of the isolates through the ages were investigated, B. altitudinis and M. furfur were found as the most abundant strains in the scalps. Especially, the isolate identified as M. furfur was most widely found in both male and female teenagers. The experimental results showed that the microorganisms distribution in human scalps would be influenced by the scalp conditions such as ages and scalp cleanliness.
Key Words: Scalp microorganisms, Bacillus altitudinis, Malassezia furfur, Staphylococcus epidermidis, Aspergillus sydowii
