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 most prevalent species belonging to these genera were: A. Keywords: Aphanoascus, Chrysosporium, dermatophytes The keratinophilic fungi are of prime importance in regard to various skin diseases prevalent in various areas. These fungi are able to utilize keratin, a fibrous protein, as sole carbon and nitrogen source and survive saprophytically in nature English, Many keratinophilic fungi frequently parasitize keratinous tissue, viz.
Some of them share certain morphological features, constituting aspecial group called dermatophytes Gugnani, The impact of keratinophilic fungi on human health seems unexplored part of various studies Shukia et al.
Dermatophytes and other keratinophilic fungi have been isolated from various keratinized part of body in animals and human Abdel-Hafez, ; Nicholis and Midgley, ; Ali-Shtayeh et al. Various keratinophilic fungi along with some dermatophytes are responsible for various skin infections, little epidemiological data on the fungal disease of skin in human is available Shukia et al. Knowledge of the frequency and extension of etiological agents of humans and animal mycosis and other potentially pathogenic fungi on the healthy hairs and nails of humans is of prime importance for understanding of epidemiological cycle of these fungi Otcenasek, ; Lee et al.
The present work is aimed at evaluating the biodiversity of keratinophilic fungi in Upper Egypt among male and female students of South Valley University at Aswan, Qena, Sohage and Red Sea Governorates. For the collection, 20 samples from each governorate and 10 samples sex were chosen at random.
Sample analysis The soil plate technique Bagy et al. After incubation isolates were cultured on SDA for identification on the basis of their colonial and morphological characters using monographic descriptions and other available literature Stockdale, ; Van Oorschot, ; Spiewak, ; Kushwala, The highest fungal 11 was collected from Red Sea samples followed by Aswan 10 and Qena 9 while lowest, 8 was recorded from Sohage samples.
It was represented by 2 species and 1 unidentified species of which A. Other keratinophilic fungal species 4 genera were also isolated, of which Aspergillus was isolated in high frequency of occurrence.
It was represented by 3 species and 1 variety, of which A. It was represented by 2 species, it were P.
It was represented by A. Chysosporium ranked second in frequency of occurrence which represented by 2 species of which C. It was represented by 6 species and 1 variety of which A. Penicillium ranked secondly among the most common from the other keratinophilic fungi genera.
It was represented by 3 species of which P. Gibberella represented by G. Aphanoascus spp. This species has of world-wide distribution El-Said, ; Ulfig et al. Maghraby found M. These fungi were isolated previously from hairs of large mammals or feathers of poultry and human Aho, ; Abdel-Hafez, , ; Ali-Shtayeh, ; Alghalibi, Dermatophytes and related fungi were represented by 5 genera of which Aphanoascus was the most frequent genus. Chrysosporium ranked second in frequency, it was represented C.
Artroderma curreyi Chrysosporium: anamorph Arthroderma curreyi , Myceliophthora verllera, and Nannizzia fulva anamorph: Microsporium gypseum were encountered through our study, those species were previously isolated by Katiyar and Kushwaha and Efuntoye and Fashanu In conclusion, highest fungal diversity 20 species was recorded from Red sea samples followed by Qena 18 and Aswan 17 while the lowest fungal diversity 16 was recorded from Sohage samples.
Red sea governorates is coastal city with high humidity level while Qena and Aswan have higher temperature range than Sohage governorate. It is well known that high temperature and humidity are favored for fungal growth.
High number of fungal species was recorded from nail samples compare to those recorded from hair samples at the four governorates and this is in agreement with the previous studies. Moharam et al. Abdel-Hafez AII. Survey on the mycoflora of goat and sheep hairs from Gaza strip.
