Antifungal properties of Brazilian cerrado plants

Ethanolic extracts from leaves of Hyptis ovalifolia, H. suaveolens, H. saxatilis, Hyptidendrum canum, Eugenia uniflora, E. dysenterica, Caryocar brasiliensis and Lafoensia pacari were investigated for their antifungal activity against dermatophytes. The most effective plants were H. ovalifolia and E. uniflora, while Trichophyton rubrum was the most sensitive among the four dermatophytes species evaluated. This study has demonstrated antifungal properties of Brazilian Cerrado plant extracts in in vitro assays

Epidemiologia e etiologia das dermatofitoses em Goiânia, GO, Brasil / Epidemiology and etiology of dermatophytosis in Goiânia, GO, Brazil

Dermatophytes are a group of closely related fungi that have the capacity to invade keratinized tissue (skin, hair, and nails) of humans and animals to produce infections called dermatophytosis. In order to review the etiology and epidemiology of dermatophytosis in GoiÔnia, GO, 1955 specimens with diagnostic suspicion of dermatophytic lesions, were collected from January to December, 1999, from the Mycology Laboratory in the Institute of Tropical Pathology and Public Health, Federal University of Goißs. A total of 445 (22.8) samples were positive for dermatophytes and Trichophyton rubrum was the most frequently isolated species (49.4) followed by Trichophyton mentagrophytes (30.8) and Microsporum canis (12.6). Concerning the location of the lesions, the inferior limbs, feet and nails together with tinea capitis were the most frequently found clinical pattern in the majority of patients. Correlation between sex, age, location of the lesions and etiologic agents is considered in the study.
