Tinha do couro cabeludo em crianças de Goiânia, Brasil

Abstract

Durante o período de janeiro de 1999 a julho de 2002 um total de 164 casos de tinha do couro cabeludo foram diagnosticados através de exames micológicos, realizados no Instituto de Patologia Tropical e Saúde Pública da Universidade Federal de Goiás. Destes pacientes, 94 (57,3%) pertenciam ao sexo masculino, com idades variando de 3 meses a 13 anos. O diagnóstico e identificação dos agentes de dermatofitoses do couro cabeludo foram feitos utilizando-se exame direto com KOH a 20% e cultivo em ágar Mycobiotic e em ágar Sabouraud dextrose acrescido de cloranfenicol. As seguintes espécies foram identificadas: Microsporum canis (71,3%), Trichophyton tonsurans (11%), Trichophyton mentagrophytes (7,9%), Trichophyton rubrum (6,7%) and Microsporum gypseum (3%). Nossos estudos mostraram que o fungo de habitat natural no animal (zoofílico), Microsporum canis foi o agente mais comum de lesões no couro cabeludo em humanos.

Dermatophyte and non dermatophyte fungi in Riyadh City, Saudi Arabia

“…Same results were reported by Costa-Orlandi and his colleagues (Costa-Orlandi et al, 2012). M. canis and T. violaceum were the most prevalent among dermatophyte isolates, these results agreed with some studies (Dias et al, 2003; Dolenc-Voljc, 2005) but did not agree with other researches (Costa-Orlandi et al, 2012; Metin et al, 2002) which found that the Trichophyton genus represented over 80% of the isolates ( T. rubrum (64.29%), T. mentagrophytes (21.43%)) while Microsporum gypseum represented 14.29%. The differences between this study and previous studies were due to the variations in environment and lifestyle (Nweze and Okafor, 2005).…”

In vitro susceptibility testing of dermatophytes isolated in Goiania, Brazil, against five antifungal agents by broth microdilution method

“…Trychophyton rubrum, T. mentagrophytes and Microsporum canis are the most common species isolated in Brazil as causative agents of dermatophytosis 1,6,7,8,21 . In Goiania city, Brazil, these same etiological agents have been recovered in studies of COSTA et al 6,7 .…”

A 7-year survey of superficial and cutaneous mycoses in a public hospital in Natal, Northeast Brazil

“…Studies performed in Brazil (8, 14, 16), Greece (9) and China (23) show that M. canis is the most prevalently isolated agent on the scalp and hair. However, in our study this agent was the second most commonly isolated, perhaps for not adapting well to the climactic conditions or because of the age group of the study population.…”
