Dermatófitos no Estado do Amazonas - Brasil

Abstract

De 696 casos de micoses superficiais, encontrados em Manaus - Estado do Amazonas, durante um período de 7 anos (1961 -1968), isolaram-se 515 amostras de fungos, das quais 440 pertenciam a espécies do grupo dos dermatófitos. O fungo predominante foi Trichophyton tonsurans, responsável por 282 das 440 amostras, ou seja, 64% do total de dermatófitos Contribuiu para este percentual, bastante elevado, o fato de ser T. tonsurans quase que o único agente causador de tinha da cabeça nas crianças de Manaus: em 242 casos de tinha tonsurante apareceu ele 234 vezes, e em 30 casos de quério, 23 vezes. Nas pessoas maiores de 15 anos, todavia, o dermatófito mais encontrado foi T. mentagrophytes; apareceu ele 106 vezes, contra apenas 16 de T. tonsurans, em 145 amostras de dermatófitos isolados deste grupo

From 696 cases of superficial mycoses diagnosed in Manaus -State of Amazonas, within a sevenyear period (1961-1968), the author obtained 515 strains of fungi, including 440 strains which belonged to the dermatophyte group. Trichophyton tonsurans was the predominant species; in fact, it is the most common dermatophyte isolated from human cases in the States of Northern Brazil, as has been shown by other investigators. In the present work, T. tonsurans was the etiological agent in 64% of the 440 cases of dermatophytoses. 111is high percentage was due mainly to the fact that T. tonsurans is almost solely responsible for tinea among the children of Manaus. Df 242 cases of ring'Norm of the scalp and of 30 cases of Kerion, T. tonsurans was isolated from 234 and 23 cases respectively. In adults, however, Thichophyton mentagrophytes was the most common agent of tinea; of 145 strains of dermatophytes isolated from adults 106 were T. mentagrophytes and 16 were T. tonsurans.
