Prevalence of tinea capitis in Ethiopian schoolchildren.

摘要: Summary The prevalence of dermatophytosis and the spectrum dermatophyte species were determined in children attending two schools Addis Ababa, Ethiopia. Demographic clinico-dermatological data collected. Specimens taken for microscopy culture from all suspected lesions. Dermatophyte identified by morphology biochemical tests, supplemented sequencing rDNA ITS 2 region selected isolates. From Biruh Tesfa Elementary School (BTES) 824 students, Mount Olive Academy (MOA) 124 included. In BTES 513 (62.3%) students clinically diagnosed with dermatophytosis, 463 (90.3 %) them tinea capitis. 200 consecutive samples BTES, 66 MOA, 75 62%, respectively, contained fungal elements at microscopy. 163/496 (33%) culture-positive, which 149 (91.4%) grew dark purple colonies as Trichophyton violaceum, while 244 (49.4%) contaminated. A few strains slowly developing white to cream colonies, T. verrucosum, 12 violaceum. MOA 44 (66.7%) 38 (87%) one (2.3%) 33% showed no growth. Four isolates T.violaceum confirmed DNA-sequencing. Dermatophytosis was thus 55–62% screened different socioeconomic standards Ethiopian capital. violaceum constituted 87–90% White variants 16 cases.
