ABSTRACT

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.


Se informan los resultados obtenidos tras la búsqueda de dermatofitos utilizando la técnica de Vanbreuseghem en un total de 68 muestras de suelo recolectadas de favelas, escuelas, plazas, playas y sitios deshabitados en la ciudad de João Pessoa, PB, Brasil. Se aislaron 48 cepas pertenecientes a 6 especies distintas de dermatofitos a partir de estos suelos. Dentro de las especies geofílicas fueron identificadas Trichophyton terrestre (25,0%), Microsporum gypseum (20,8%) y Anthroderma gypsea (2,1%); dentro de las zoofílicas, T. mentagrophytes var. mentagrophytes (37,5%) y entre las antropofílicas T. tonsurans (4,2%). El crecimiento del 75% de los dermatofitos se dio a pH alcalino (7,02-9,00). Se concluye que la presencia de estos dermatofitos en el suelo no debería ser subestimada, dado que algunas de las especies identificadas son agentes de dermatofitosis para los humanos y los animales.
