DERMATOPHYTOSES IN MEXICO-CITY

We analysed 2350 biological samples from patients with a clinical diag nosis of superficial mycoses who attended outpatient services over a 7 -year period. Samples of scales were processed by direct microscopic e xamination with 15% KOH and cultured on Sabouraud glucose agar with ch loramphenicol and cycloheximide. Laboratory examination confirmed derm atophytosis in 860 (36.6%) cases, of which 80.9% were caused by Tricho phyton rubrum. The most frequently observed dermatophytoses were tinea unguium (60%) and tinea pedis (25.6%). In agreement with previous obs ervations, we demonstrate that T. rubrum continues to increase in Mexi co.
