| biochemical studies of pigments from a pathogenic fungus microsporum cookei. v. evidence for the transmembrane permeability of xanthomegnin across phospholipid bilayer membranes. | direct evidence is provided for the transmembrane permeation of xanthomegnin across phospholipid bilayer membranes using ascorbate-loaded liposomes. this process may be associated with an uncoupling effect on the oxidative phosphorylation of mitochondria. | 1978 | 212291 |
| [research of keratinophiles in the soil and their effects on human cutaneous pathology in the lyons area]. | between 1967 and 1977, the systematic research of keratinophiles of the ground in a radius of 30--50 km around lyon, has shown the ubiquitarian predominance of microsporum nanum, which is probably the most ancient occupant of the ground. the most intensive areas of human and animal occupation in the rhodanian tract show the predominance of microsporum gypseum, which is scarcely found in man. sporadic localizations, tightly limites, bound to cirulcation axes and international gathering, let us de ... | 1979 | 488487 |
| electron microscopic evidence of phosfon d-induced alterations in the membranes of the dermatophytic fungus microsporum cookei. | the dermatophytic fungus microsporum cookei was cultivated for 24 h in the presence of subinhibitory and inhibitory concentrations (50 and 100 micrograms/ml) of phosfon d, a growth retardant for higher plants also affecting fungal development, and its toxic effects were examined at the ultrastructural level. in both treatments, phosfon d attacked the membranes, whose structural integrity was clearly compromised with damage of particular severity to mitochondria, nuclei and endoplasmic reticulum. ... | 1979 | 530091 |

| partial characterization of proteolytic enzymes of microsporum canis and microsporum cookei. | characterization by proteinase inhibitors of the enzymes produced by microsporum spp. revealed that microsporum canis and microsporum cookei produce serine proteinase(s), but only m. canis expresses aspartic and cysteine proteinases and probably a metalloproteinase. both m. canis and m. cookei expressed metalloelastinolytic proteinases. all the proteinase types have been implicated in the pathogenicity of a wide range of microorganisms. | 1996 | 9009645 |

| electron microscopy of microsporum cookei after 'in vitro' treatment with protoanemonin: a combined sem and tem study. | the ranunculaceous derivative protoanemonin (pra) was studied as an antifungal agent on the dermatophyte microsporum cookei. the ultrastructural changes that pra brought about in this fungus were observed with both the transmission and scanning electron microscopes. the main anomalies noted were abnormally shaped hyphae and within the cytoplasm, multimembranous bodies which were irregular in shape and size, and tubules of 25 and 60 nm in diameters. mitochondria, nuclei and vacuoles were also var ... | 1989 | 2615800 |
| ultraviolet-mediated antimycotic activity of alpha-terthienyl on microsporum cookei. | alpha-terthienyl (alpha-t) in the presence of uv-a irradiation reduced the growth rate of microsporum cookei. in the dark, alpha-t accumulated in small diffuse vacuoles within the hyphae. after uv-a treatment, alpha-t caused damage to the membranes of the nucleus, mitochondria and endoplasmic reticulum. plasmolytic and autolytic changes occurred resulting in plasma membrane breakage and cell wall aberrations. uv-a activated alpha-t would appear to target membrane proteins. | 1990 | 2093120 |
| biochemical studies of pigments from a pathogenic fungus microsporum cookei. iii. comparison of the effects of xanthomegnin and o-methylxanthomegnin on the oxidative phosphorylation of rat liver mitochondria. | the effects of xanthomegnin and o-methylxanthomegnin on the oxidative phosphorylation of rat liver mitochondria were compared. the n-octanol/water partition coefficient of xanthomegnin was markedly enhanced by o-methylation, but o-methylation of xanthomegnin reduced the uncoupling effect on the respiratory system of mitochondria. analogous results were obtained in the uncoupling action of 5-hydroxy-1, 4-naphthoquinone (juglone) and 5-methoxy-1, 4-naphthoquinone (o-methyljuglone) on the oxidative ... | 1976 | 939756 |
| fungal toxicity of phosfon d and its reversion by lipids. | the growth retardant phosfon d inhibits the growth of some yeasts and human pathogenic filamentous fungi. the toxic effects of the compound on the dermatophyte microsporum cookei were completely reversed by adding ergosterol and oleic acid to the medium. the significance of these findings is discussed. | 1978 | 666296 |
| an unusual lipid in the human pathogenic fungus epidermophyton floccosum. | the dermatophyte epidermophyton floccosum contains an unusual lipid characterized as 1(3),2-diacylglyceryl-3(1)-o-4'-(n,n,n-trimethyl)homoserine. its concentration in e. floccosum is approx. 15% of the polar lipids. the role of this lipid in the biosynthesis of polar lipids and fatty acids is not yet known. however, it is interesting from a chemotaxonomic viewpoint that the lipids from two other genera of dermatophyte, microsporum cookei and trichophyton rubrum do not contain this novel lipid. | 1979 | 486519 |
