[Higher fatty acid composition of enterococci].

The content of unsaturated fatty acids in enterococcal cells has been found to have no essential relation to the composition of the culture medium. When cultivated in the same media, S. faecium had the degree of lipid unsaturation 1.5-2 times higher than S. faecalis. Mobile enterococci are sharply differentiated from immobile species by the content of cyclopropanic acid with 19 carbon atoms, constitute a heterogenous group and consist of at least 2 taxons, differing in the content of acids with 18 carbon atoms and the degree of lipid unsaturation.

[Phagocytosis and the antiphagocytic factors in mycobacterial infections].

Peculiarities of phagocytosis of pathogenic, conditionally pathogenic ristic is given to antiphagocytic factors which permit some species of these processes with immunity are considered in the paper. A characteristic is given to antiphagocytic factors which permit some species of mycobacteria to avoid protective bactericidal reactions of mammals and to reproduce in phagocytes. Expression of mycobacterial virulence depends on the character of interrelations between the pathogen and cells of reticuloendothelial and immune systems. Interpretation of this mechanism is important in development of the methods of infection control and creation of efficient vaccines.

[Hygienic properties of cellophane film intended for food packaging].

The cellophane films intended for wrapping food products were studied. Investigations have established the presence of these films of the cellulose xanthogenate and products of its decomposition, of carbon bisulphide in particular. With their joint presence the determination of carbon bisulphide and hydrogen sulphide was done colourimetrically, the sensitivity of this method being 0.005 mg/l. Migration of carbon bisulphide from the cellophane into the atmosphere and water was investivaged. An interconnection between the amount of the migrated carbon bisulphide and the odour of aqueous cellophane extracts was disclosed. To improve sanitary and chemical properties of cellophane a more intensive washing off of sulphur-containing compounds from it is recommended.
