Diversity of Keratinophilic Fungi on Human Hairs and Nails at Four Governorates in Upper Egypt

Abstract

The mycobiota of 160 hair and nail samples collected from 4 different governorates in upper Egypt were estimated using soil plate method for isolating keratinophilic and dermatophytic fungi. Twenty-three fungi were recorded on both hair and nail samples collected from the four governorates. Highest fungal diversity (20) was collected from Red Sea samples followed by Qena (18) and Aswan (17) while lowest fungal diversity was recorded from Sohage samples. The common genera were Aphanoascus, Aspergillus, Penicillium, Paecilomyces and Chrysosporium. The most prevalent species belonging to these genera were: A. fulvescens, Aphanoascus sp. A. flavus link, A. flavus var. columnaris, P. chrysogenium. P. lilacinus and C. sulfureum. True dermatophytes such as Nannizzia fulva appeared in 20~30% of the male samples.

“…Other Gram-positive bacteria such as Lysobacter, Nesterenkonia, Kocuria, Microbacterium and Gram-negative bacteria such as Vibrio, Xanthomonas, Stenotrophomonas, Chryseobacterium, Fervidobacterium, Thermoanaerobacter, and Nesterenkonia are also potentially known to produce keratinases enzyme [ 44 ]. Fungal species of Microsporum, Epidermophyton, Trichophyton, Chrysosporiu , are well known keratinophilic fungi and also have potential ability to degrade keratin fibers [ 45 ]. Along with enzymes, specific peptides (digest of proteins) have also been widely used in cosmetic preparations.…”

A Microbial Approach to Forensic Science

“…A study was conducted in South Valley University, Quena, Egypt. They found that Aphanoasus was the most common genus from the students of both sexes (Gherbawy et al 2006).…”
