Dermatophytoses in forestry workers and farmers

To assess the frequency of superficial mycoses in forestry workers and farmers in the rural region of Duzce, a total of 467 residents of the rural region were examined for dermatomycosis infection. Of these, 349 were forestry workers and 118 farmers. All specimens collected were analysed by direct microscopy and culture. Tinea pedis et manus was found in 23 (19.4%), and onycomycosis in 21 (17.7%) farmers. Tinea pedis et manus was found in 50 (14.3%), and onycomycosis in 28 (8%) forestry workers. One tinea corporis, two tinea inguinalis and two erosio interdigitalis cases were determined in the farmer group but no cases of tinea corporis, tinea inguinalis, or erosio interdigitalis were found in the forestry group. In total, five tinea versicolor cases were found in the two groups on clinical examination but no agent positivity was yielded in mycological cultures. The most frequently isolated agent in the two groups was Trichophyton rubrum. The frequencies of superficial mycosis and onychomycosis were found to be higher in the farmer group than in the forestry group, although similar aetiological agents were isolated in both groups. The farmers had greater rates of contact with pathogenic fungi present in soil as well as from infected farm animals than the foresters; furthermore, animal husbandry, and the wearing of rubber shoes and nylon socks were more frequent in the farmer group. These results suggest that habits such as the wearing of rubber shoes and nylon socks, and the practice of animal husbandry may be the most important factors in determining the frequency of superficial mycoses and aetiological agents in forestry workers and farmers. To our knowledge, there is no previous report about dermatophytoses in forestry workers.
