Abstract
Of 10 057 specimens of scrapings from skin, nails and scalp examined for dermatophytes, yeasts, pityriasis versicolor and systemic mycoses between 1963 and 1973, 30.4 percent were positive for fungi. Skin produced the highest proportion (68.6 percent) of positive scrapings, scalp the lowest (4.2 percent). Trichophyton rubrum was the predominant species (23.6 percent); of lesser prevalence were Microsporum canis (9.3 percent), T. mentagrophytes (8.4 percent) and Epidermophyton floccosum (4.8 percent). Double infections were encountered on 102 occasions; T. rubrum and Candida parapsilosis were the most frequent cohabiting species. The introduction in 1966 of periodic acid-Schiff staining for routine examination of scrapings resulted in better diagnostic results, particularly in the case of culturally nonproductive specimens and cases of pityriasis versicolor. Blastomyces dermatitidis and Cryptococcus neoformans were isolated from two patients in the course of routine investigation for dermatophytes.
