[Factors affecting the participation of bacteria of the genus Bdellovibrio in the self-purification processes in the Syr Darya River].

The effect of season, temperature and abundance of microflora on the interrelations between bdellovibrions and host-bacteria in the syr Daryo river compared with the Oka has been studied. These factors and composition of allochthonic gram-negative bacteria in the river influence on the abundance of Bdellovibrio and extent its participation in the self-purification of basins.
