[The characteristics of the biological properties of Shigella dysenteriae 1 circulating in the USSR and India: its biochemical activity and agglutinability].

The properties of 71 S. dysenteriae 1 strains isolated from patients in the USSR and India in 1986-1988 were studied. The cultures possessed typical biochemical and serological properties. As revealed in this investigation, high fastidiousness of this infective agent to the quality of synthetic nutrient could become the cause of false negative reactions in different substrates used for the identification of enterobacteria, thus leading to diagnostic mistakes. The variability of the biochemical activity of different strains with respect to arginine, glycerol, maltose and trehalose (as well as the stability of these signs) was regarded as the theoretical substantiation of the possibility, in principle, to work out the scheme for the subdivision of S. dysenteriae 1 into independent biochemical variants.
