Dermatophyte and Cyclohexamide-Resistant Fungi Isolated from Patients with Tinea Capitis and from Air in Hospitals in Minia, Egypt

Out of 210 tinea capitis cases studies, 16 were negative when examined with KOH, among the remaining 194 cases, 123 were males (63.4%) and 71 were females (36.6%) and the age of incidence ranged between 7 and 15 years. Microsporum was the main causal agent being identified in 82 cases (42.3%) and was represented by 5 species among which M. canis was common in Egypt (55 cases, 28.4%). Trichophyton constituted 32% and was represented by 8 species among which T. violaceum was the most common (24.2% of total cases). Candida were isolated from 3.6% of total cases. The 47 species and twenty-five genera from nondermatophyte-cyclohexamide resistant fungi were recovered from the diseased skin tissue. Penicillium and Aspergillus were the most abundant followed by Scopulariopsis, Alternaria, Thermoascus, Chrysosporium and Cladosporium. Studies of the air-borne fungi in-door the hospital wards revealed the occurrence of 57 species belonging to 28 genera, among which Aspergillus flavus, Penicillium chrysogenum, p. corylophilum, A. niger, Tritirachium rosum and Alternaria alternata were the most common. Results of the out-door experiments were basically similar to those of the in-door experiments.
