COSTA, Théo Rodrigues et al. Etiology and epidemiology in dermatophytosis in Goiânia, State of Goiás, Brazil. Rev. Soc. Bras. Med. Trop. [online]. 1999, vol.32, n.4, pp. 367-371. ISSN 1678-9849. http://dx.doi.org/10.1590/S0037-86821999000400006.
Dermatophytoses are superficial infections that may lead to lesions of keratinized tissues, like skin, hair and nails. A total of 6068 individuals from Goiânia,GO, with suspected dermatophytic lesions were examined over a period of five years (1993-1997) in order to determine the incidence and etiology of dermatophytosis. Material collected from different body parts was submitted to direct microscopic examination using KOH, cultured in Sabouraud agar and microscopically examined for colony morphology, with the identification of 1595 dermatophytes. Trichophyton rubrum (37.4%), T. mentagrophytes (36.4%) and Microsporum canis (16%) were the species most frequently isolated. Dermatophytes were more frequently found producing lesions in the feet (30.5%), inguinal and crural regions (17,8%) and glabrous body regions (15.5%). The distribution of the different infected body sites was determined in terms of the respective etiologic agents found. Better hygiene conditions and an early diagnosis are the most important tools to control and reduce the incidence of dermatophytosis in Goiânia, GO.
