    Abstract:
    In order to know mycosis frequency in the North of the State of Puebla, Mexico, in habitants from the communities of Ayotoxco, Mazatepec and Zacatipan were studied. Previous medical study biological samples were submitted to direct examination, smear and culture. Histoplasmin and sporotrichin skin test were applied to 57 individual from Zacatipan. From 110 patients 146 mycological studies were performed. Eighty six cases (59%) of mycosis were detected: 43 finger or toenails onychomycosis, 25 tinea pedis, seven tinea capitis, four cases of tinea manum and, finally, five cases of seborrhoeic dermatitis and two of pitiriasis versicolor. We isolated: 18 streins of dermatophytes, mainly Trichophyton rubrum and T. mentagrophytes (11 and 5 strains respectively); 12 cultures of non-dermatophytes filamentous fungi; six cases of mycelia sterile; six yeast strains, most of them Candida spp but none C. albicans. From 57 patients to whom skin tests were applied, five of them (8.8%) were positive to both antigens; ten positive (17.6%) only to histoplasmin and eight (14%) to sporotrichin. This study showed that rural population from Puebla present a high frequency of superficial mycosis (61% of mycological studies). Considering the percentage of positive skin test we suppose that there are many not diagnosed sporotrichosis and histoplasmosis cases.
