[Identification of Mycobacteria species by liquid-gas chromatography].

Principles and characteristic features of gas chromatographic indentification of Mycobacterium from the fatty acid composition were considered. The results of their differentiation by gas chromatography agree with Myco. indentification according to the complex of morphological, cultural and biochemical, and other characteristics. Copyrolysis has a number of advantages compared to the routine identification techniques, i.e. it reduces the time needed for the analysis down to 2-3 hours; allows one to use small portions of microbial mass; and provides for a complete automation of the procedure. The advisability of putting the gas chromatographic identification of Myco. species into practice of the antituberculosis medical and veterinary institutions is pointed out.

[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.
