“…The adherence causes breakage of the hair shaft. Piedra was first subdivided into two types, black piedra and white piedra, by Horta in 1911 (21). The two types tend to occur in different climates.…”

Superficial fungal infections represent an important cause of morbidity for people worldwide, particularly in the tropics. Fungal infections affect the skin, hair, or the nails, and tend to thrive in the heat and humidity of tropical countries. Because of environmental and cultural factors unique to the tropics, the causative organisms and presentation of these infections may differ from those in industrialized countries. Treatment options include topical and systemic therapy. However, social and socioeconomic factors in developing tropical countries may necessitate different treatment approaches to achieve success.

ResumoAnálise das concepções de natureza dos livros didáticos sob uma perspectiva holística e transformadora. Fomenta discussões entre os profissionais da educação sobre o papel do livro como reprodutor das ideologias dominantes em relação aos recursos naturais, a partir do estudo de uma amostra de 67 títulos da área de Ciências. Discute a predominância da visão ocidental e capitalista de homem dominador da natureza e suas implicações sobre a educação e sociedade. Conclui que o livro de Ciências das séries iniciais, apesar das mudanças em alguns aspectos, continua com a visão do papel do homem dominador da natureza, dificultando a conscientização e o respeito sobre os problemas ambientais. Palavras-chave: analogias, ensino de biologia, planejamento de aulas AbstractAnalysis of the conceptions of nature of didactic books under a holistic and transforming perspective.

The predominance of the vision argues occidental person and capitalist of dominator man of the nature and its implications on the education and society.

“…It is characterized by the formation of firmly attached, black and hard nodules around the hair shaft. In 1911, Horta clearly differentiated black piedra from the white variety and considered that the fungus causing the first was a species of Trichosporon [1]; later it was named Trichosporon hortai [2]. When ascospores were discovered in the nodules, the fungus was related to the Ascomycotina and given its present name [3].…”

Ultrastructural aspects of hair digestion in black piedra infection

The ultrastructural pattern of human hair infection by Piedraia hortae in vivo has been studied. The fungus destroyed the cuticular layers of the hair and was able to penetrate deeply into the cortex. The course of destruction of human hair is described and compared with that produced by other fungi. Two well-defined types of cortex digestion were characterized. The slow rate of keratin degradation at the cortex together with the compacted stromatic organization of the nodules are argued as the main reasons that guarantee the long survival of the fungus, and therefore the chronic course of the disease. The data provided in this paper may help to understand the mechanisms that regulate the pathogenicity of this fungus.
