چکیده

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 in all cases.

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...

The 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...

Weather 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...

Characterization of plant growth promoting rhizobacteria associated with chickpea (Cicer arietinum L.)

Plant growth promoting rhizobacteria (PGPR) are known to influence plant growth by various direct or indirect mechanisms. In search of efficient PGPR strains with multiple activities, a total of 150 bacterial isolates belonging to Bacillus, Pseudomonas, Azotobacter and Rhizobium were isolated from different rhizospheric soil of chick pea in the vicinity of Allahabad. These test isolates were bi...
