“…mentagrophytes shows that lipids do not absolutely inhibit the growth of dermatophytes. The higher cellular content of lipids in all the dermatophytes studied show them to be lipogenic as previously reported by the presence of fatty acid synthetase in T. rubrum (25). These findings and previous reports (8) on growth of dermatophytes in lipid media suggest that sebum and other lipids in human skin, hair and nails may not absolutely inhibit the growth of dermatophytes.…”

Summary: Growth pattern of certain dermatophytes in varied substrates with their biochemical constituents have been studied. This study was carried out with isolates obtained from patients of Madras, India. It was observed that better growth and higher amounts of cell constituents occurred in media with proteins and complex media like Sabouraud's dextrose liquid medium than in other substrates like carbohydrates and lipids when supplied as a single source of nutrients. Liquid media were observed to produce a better growth than solid media as far as quantity of growth was concerned. Correlating these findings in vitro to in vivo human infections it is suggested that dermatophytoses may be considered as diseases of healthy rather than the diseased human keratinous structures. Zusammenfassung: Das Wachstumsverhalten von gewissen Dermatophyten in abgewandelten Nährmedien wurde zusammen mit ihrer chemischen Zusammensetzung untersucht. Diese Untersuchung wurde an Pilzen durchgeführt, die von Patienten aus Madras, Indien, isoliert wurden. Es konnte festgestellt werden, daß besseres Wachstum und eine höhere Menge der Zellbestandteile vorkamen, wenn Nährböden verwendet werden, die Proteine enthielten bzw. in kompletten Medien wie Sabouraud's Dextrose Medium (flüssig). Geringeres Wachstum und weniger chemische Zellbestandteile wurden erhalten, wenn Kohlen‐hydrate oder Lipide als einzige Nährstoffquelle verwendet wurden. Flüssige Medien führten hinsichtlich der Masse an produziertem Mycel zu besserem Wachstum als feste Medien. Aus der Übertragung dieser in vitro Ergebnisse auf die Verhältnisse bei der Infektion von Menschen wird gefolgert, daß Dermatophytosen eher als Erkrankung von Gesunden als von kranken menschlichen verhornten Strukturen anzusehen sind.

Phospholipid and neutral lipid composition of undecanoic acid (UDA) resistant mutant of Trichophyton rubrum were compared with those of the UDA sensitive parent strain of this dermatophyte. When grown in glucose-peptone broth under identical conditions, contents of neutral and phospholipids in UDA resistant mutant were nearly double of those in the UDA sensitive parent strain. Glyceride, sterol, sterol ester and phospholipid contents of mycelium increased when UDA sensitive strain was grown in presence of low concentration of UDA, sufficient to cause partial growth inhibition of this strain. UDA in growth medium did not change the lipid composition of the UDA resistant mutant.

Effects of undecanoic acid (UDA) on germination of microconidia and elongation of germ tubes in UDA sensitive (udas) wild type Trichophyton rubrum and UDA resistant (udar) mutant derived from it, were studied. UDA inhibited conidial germination of udas and udar strains at 30 microgram/ml and 120 microgram/ml respectively which were minimum inhibitory concentrations of UDA for these two strains. When spores from both udas and udar were germinated in presence of subinhibitory concentration of UDA, germ tube growth was short. The elongation of germ tubes of spores pregerminated in absence of UDA was also inhibited by dose of UDA not sufficient to inhitib germination.
