Interaction of sporidesmin, a mycotoxin from Pithomyces chartarum, with lipid bilayers.
Sporidesmin, a mycotoxin from Pithomyces chartarum is a hydrophobic molecule. It can therefore be easily incorporated in the cell membrane, where it is likely to cause changes in the bilayer organization and the properties of membrane proteins. In order to understand the redox behaviour of sporidesmin in a hydrophobic environment, we have investigated the effects of oxidized and reduced sporide...
متن کاملAbsence of sporidesmin production by twelve Texas isolates of Pithomyces spp.
Twelve isolates of Pithomyces spp. from Texas were tested for sporidesmin toxin production, using both high-performance and thin-layer chromatography techniques. None of the Texas isolates produced the toxin under the conditions used. A control toxigenic New Zealand isolate, Pithomyces chartarum strain C, was grown simultaneously under the conditions tested and was found to produce sporidesmin ...
متن کاملFurther study of the lipids from Pithomyces chartarum (Sporidesmium bakeri) and related fungi.
A study of the lipids of Pithomyce8 chartarum (Berk. & Curt.) M. B. Ellis (which has replaced the name Sporide8mium bakeri Syd. used previously) has shown that their fatty acid composition differs from that of other fungi hitherto examined in containing large quantities of both linoleic acid and palmitic acid (Hartman, Hawke, Morice & Shorland, 1960). The main object of the present work has bee...
متن کاملWeather and Plant Age Affect the Levels of Steroidal Saponin and Pithomyces chartarum Spores in Brachiaria Grass
Brachiaria species are cultivated worldwide in tropical and subtropical climates as the main forage source for ruminants. Numerous tropical and warm-season grasses cause hepatogenous photosensitization, among them several species of Brachiaria. Steroidal saponins present in these plants may be responsible for liver damage. However, sporidesmin and other hepatotoxic mycotoxins are likely to prod...
متن کاملThe composition of the liver lipids of sheep and the effect of early sporidesmin poisoning.
Facial eczema, a disease of sheep and, to a lesser extent, of cattle, has long been known in the North Island, New Zealand. The disease is contracted by grazing in pastures infected with the fungus Pithomyces chartarum (Commonwealth Mycological Institute Herbarium no. 74473). Synge & White (1959) isolated from cultures of this fungus a metabolic product which they named sporidesmin. Crystalline...
