Dermatophytes from urban soils in João Pessoa, Paraíba, Brazil.

A total of 68 soil samples was collected from "favelas" (slums), schools, public squares, beaches and vacant lots in the city of João Pessoa-PB, Brazil. A search for dermatophytes in these soils was carried out by using the Vanbreuseghem technique. As a result, 48 strains and 6 dermatophytes species were isolated. Trichophyton terrestre (25.0%), Microsporum gypseum (20.8%) and Anthroderma gypsea (2.1%) were identified among the geophilic species, and T. mentagrophytes var. mentagrophytes (37.5%) among the zoophilic species and T. tonsurans (4.2%), among the anthropophilic species. The growth of 75% of dermatophytes occurred in alkaline pH (7.02-9.00) and their presence in the soil should not be underestimated, since some of the identified species are aetiological agents of dermatophytoses in humans and animals.
