Isolation and identification of microbial and fungal flora from female hair samples in Riyadh Saudi Arabia

The human hair harbors several species of fungi and also bacteria. The present study was performed to determine the prevalence of keratinophilic fungi and bacteria from hair samples of femalesfrom November 2016 to April 2017. A total of 50 human hair samples were examinedusing hair-baiting techniques for isolation. After the incubation period, the number of colony forming unit was counted. The microorganisms were identified based on the colony morphology from culture and microscopic features. After purification, each representative colony was gram-stained and examined for cell morphology and gram reaction under a light microscope. Fungal isolates included were Aspergillus niger, Aspergillus flavus, Penicilliumspp, Alternaria alternata, Chrysosporium keratinophilum. Cladosporium cladosporioides and Trichosporon mucoides. Isolated bacterial species included gram positive bacteria such as Leuconostoc mesenteroidess spcremoris, Kocuriarosea, Staphylococcus haemolyticus, and the gram negative bacteria Kocurikristinae, Stenotrophomonas maltophilia, and Micrococcus luteu/ lylae. Human hair samples from females studied were found have several fungal and bacterial isolates, some of which can cause some serious disease in humans. Health
