Abstract

We have used the scanning electron microscope to investigate the changes that occur in scalp hair during infection with Trichophyton violaceum. We provide information on the morphology of these dermatophytes and present evidence that their hyphae dig tunnel-like burrows into the hair shaft, dissociating hair into keratin fibrils.

2. ALOPECIA AEEATA HAIKS: A SCANNING ELECTRON MICROSCOPE STUDY.

Abstract

The fractured ends of exclamation mark hairs were found to be quite distinct from those of normal hairs broken by traction when examined with the scanning electron microscope. The cuticular scales of exclamation mark hairs, telogen hairs from around lesions, hairs from unaffected parts of the scalp, and hairs from normal subjects were found to possess smooth edges when first produced. More distally, however, the edges of the scales became jagged, although their configuration remained unaltered, in all cases. [ABSTRACT FROM AUTHOR]
