“…A. beaveri , A. hartigii , E. amstelodami , M. trigonosporus , N. dimidiatum , P. lagunculariae , P. variotii , S. coprophila , and T. atroroseus were recorded in this research. Bokhary et al [28] isolated A. flavus , G. candidum , Penicillium chrysogenum , and Scytalidium album from 19 human hairs collected from Riyadh, Saudi Arabia. S. dimidiatum was reported as a human skin and nail pathogen in 2009, Campbell and Moulder [29]; Kombila et al [30] estimated it as an etiological agent of surface skin infections.…”

A diverse population of fungi colonizes human hair and skin due to millions of years of functional integration and mutual adaptation. The human body, with its fungal communities, forms a complex entity. Microbial imbalance is promoted by instabilities in the host–mycobiota interaction system, which can be related to the development of various diseases. By morphological and molecular identification, 15 genera comprising 24 species were isolated from 18 scalp samples collected from girls. Yeast‐like structures were the most common species in this study; they were recovered from six samples (33.3%). They were represented by five species: Arachniotus ruber; Cosmospora aurantiicola; Cutaneotrichosporon oleaginosum; Geotrichum candidum and Suhomyces tanzawaensis. For the synthesis of zinc oxide nanoparticles (ZnO NPs), an aqueous extract of Zingiber officinale was utilized as a reducing and capping agent. The prepared NPs tested by X‐ray diffraction, they had a hexagonal wurtzite structure. Most of the ZnO NPs were spherical, and their diameter was about 38.9 nm using a transmission electron microscope. ZnO NPs of the Fourier‐transform infrared spectroscopy spectra were recorded in the range of 400–4000 cm−1. UV–visible diffuse reflectance spectroscopy showed the 200–800 nm wavelength range. ZnO NPs showed the highest activity against Ambrosiella hartigii Ambh2; Cladosporium cladosporioides Cladcl12; C. cf. cucumerinum Cladcu13; S. tanzawaensis Suht34, with minimal inhibitory concentrations 1.25 × 103 µg/mL on the four isolates.

The objective of this study was to evaluate the occurrence of mycoflora in 30 samples of healthy goat's hair and sheep wool collected from different localities in Taif, Saudi Arabia, and the ability of some fungal isolates for keratinase activities. Sixty four species belonging to 28 genera were collected from the two substrates. The wool of sheep was polluted with fungi than goat hairs, and contained high total counts and number of fungal genera and species. Nine species of true dermatophytes isolated belonged to Microsporum (3 species) and Trichophyton (6 species). Several keratinophilic species were isolated of which, Chrysosporium indicum, Chrysosporium keratinophilum and Chrysosporium tropicum were the most prevalent. The commonest saprophytes in order of frequency were members of the genera, Aspergillus, Penicillium, Alternaria and Cochliobolus. In addition, the other genera found included Acremonium, Chaetomum, Cladosporium, Cochliobolus, Fusarium, Mucor, Paecilomyces, Phoma, Rhizopus, Scopulariopsis, Stachybotrys, Trichoderma and others. Five species from 20 tested isolates (Aspergillus niger, C. keratinophilum, C. tropicum, Microsporum gypseum and Trichoderma viride) had high keratinase activity. The results of this study indicate that both goat hair and sheep wool provide a suitable habitat for dermatophytes and other keratinophilic fungi. Most of these fungi play an important role in the degradation of keratin substrates, so that they can help preserve the environment and reduce pollution.
