Summary of "Experimental white piedra: a robust approach to ultrastructural analysis, scanning electron microscopy, and etiological discoveries."

White piedra is a clinical condition caused by Trichosporon species (1,2). The most distinctive feature of this mycosis is the production of white-brown nodules adhered to the hair shaft that may easily be detached, in contrast to black piedra nodules (3). Despite awareness of white piedra in the medical field since the 19th century (4), there is little knowledge about its mechanisms of infection in humans (5,6). Furthermore, it may occur more frequently than current estimates report, especially in tropical countries where it is believed that underdiagnosis occurs (5). No published studies have explored the chemical nature of white piedra nodules, but the observation of ultrastructural parasitism has been described (7,8). Here, we present the first in vitro study of white piedra with associated ultrastructural and chemical analyses. This article is protected by copyright. All rights reserved.

Medical and Biotech [MESH] Definitions

Either of two diseases resulting from fungal infection of the hair shafts. Black piedra occurs mainly in and on the hairs of the scalp and is caused by Piedraia hortae; white piedra occurs in and on the hairs of the scalp, beard, moustache and genital areas and is caused by Trichosporon beigelii.

A mitosporic fungal genus causing opportunistic infections, endocarditis, fungemia, and white PIEDRA.

A scanning microscope-based, cytofluorimetry technique for making fluorescence measurements and topographic analysis on individual cells. Lasers are used to excite fluorochromes in labeled cellular specimens. Fluorescence is detected in multiple discrete wavelengths and the locational data is processed to quantitatively assess APOPTOSIS; PLOIDIES; cell proliferation; GENE EXPRESSION; PROTEIN TRANSPORT; and other cellular processes.

Components of a cell produced by various separation techniques which, though they disrupt the delicate anatomy of a cell, preserve the structure and physiology of its functioning constituents for biochemical and ultrastructural analysis. (From Alberts et al., Molecular Biology of the Cell, 2d ed, p163)

A scanning probe microscopy technique that uses an ultramicroelectrode as the scanning probe that simultaneously records changes in electrochemical potential as it scans thereby creating topographical images with localized electrochemical information.
