RESUMO
Changes in the fractional composition of lipids isolated from millet, rice and semolina artificially infected with the microscopic fungus Fusarium sporotrichiella Bilai were followed. The lipid complex was found to undergo marked changes and to yield toxic sterololactones.

A decrease in the persistence characteristics of staphylococci under the influence of microclimate in a spelean pit has been demonstrated under experimental conditions. Clinical investigations have confirmed the capacity of speleotherapy to decrease the microbial contamination of the upper respiratory tract and to inhibit the persistence properties of staphylococcal microflora in children with respiratory allergosis, which seems to be the basis of the positive effect achieved by treatment with microclimate in a spelean pit.

The chromatographic method for determining the toxicity of the cereal crop grain affected by micromycates F. sporotrichiella is proposed. The method is based on the separation of the lipids extracted from the grain under examination in a thin layer of the silica gel and detection on the chromatogram of two toxic fractions with Rf-0.06 and 1.22 fluorecent in the UV-light by emitting greyish-green and emerald-green coloured light. The chromatographic method is more sensitive, visually obvious and quicker by comparison with the biological ones.
