    This study focuses on determining the frequency of dermatophytes in individuals engaged in agriculture in the Quillán Loma area. Dermatophytes, the most common agents of superficial mycoses worldwide, affect keratinized structures such as skin, nails, and hair. Farmers are particularly vulnerable due to their long working hours, contact with organic matter and animals, use of closed footwear, and humid conditions. The study, designed as cross-sectional, descriptive, observational, and prolective, included 52 participants with lesions suggestive of onychomycosis and athlete’s foot. Samples were collected from toenails, fingernails, sole scrapings, and interdigital spaces, and analyzed using 10% KOH, Sabouraud dextrose agar culture, microculture, and lactophenol blue staining. Microscopic and macroscopic analyses identified the etiological agents. Of the samples, 29 tested positives through KOH and culture. Nineteen dermatophytes were identified: Trichophyton mentagrophytes in 12 cases and T. rubrum in 7 cases. Additionally, 10 non-dermatophytic molds were isolated: Fusarium (5 cases), Aspergillus (3 cases), and one case each of Scopulariopsis and Alternaria. Risk factors were validated through a survey and correlated with the dermatophytes identified in the study.
