Fig. 10From: Molecular systematics of Keratinophyton: the inclusion of species formerly referred to Chrysosporium and description of four new speciesHair perforation in vitro – keratinolysis; detail of a child’s hair after colonization by the fungus on PDA (after 21 d) at 25 °C. a Keratinophyton lemmensii (BiMM-F76). b Keratinophyton gollerae (BiMM-F250). c Keratinophyton straussii (BiMM-F78). d Keratinophyton wagneri (BiMM-F77). Intensity of attack on the hair estimated on a scale of 0 to 4 (Marchisio et al. 1994). a 0–1 = light attack to cuticle. b, c 4 = cuticle and cortex attack with about 80% destruction. d 2 = cuticle and cortex attack with about 20% destructionBack to article page
