- Incidence and biodiversity of yeasts, dermatophytes, and non-dermatophytes in superficial skin infections in Assiut, Egypt.
Objective. — The aim was to identify the incidence of the causal agents from dermatophytes,
non-dermatophytes and yeasts in Assiut Governorate employing, beside the morphological and
physiological techniques, the genotypic ones.
Patients. — Samples from infected nails, skin and hair were taken from 125 patients.
Materials and methods. — Patients who presented with onychomycosis, tinea capitis, tinea
corporis, tinea cruris and tinea pedis during the period from February 2012 to October 2015 were
clinically examined and diagnosed by dermatologists and were guided to Assiut University
Mycological Centre for direct microscopic examination, culturing and identification.
Results. — Onychomycosis was the most common infecting (64.8% of the cases) followed by
tinea capitis (17.6%). Direct microscopic preparations showed only 45 positive cases, while 96
cases showed positive cultures. Infections were more frequent in females than males. Fifty-one
fungal species and 1 variety were obtained. Yeasts were the main agents being cultured from
46.02% of total cases. Non-dermatophytes were the second etiologic agents. Aspergillus was
responsible for infecting 19.47% of total cases and dermatophytes appeared in only 15.93% of the
cases.
