title: [Possibility of existence and multiplication of Mycobacteria in the soil].
abstract: The time of the survival of Mycobacterium bovis in the soil of pastures depended on the physicochemical composition and biological activity of the soil. In clay soils M. bovis retained their virulence for as long as 2 months (at the depth of 2 cm in high- and medium-posted solonetz) to 12 months (at the depth of 10 cm in crust solonetz). The M. bovis strains under study multiplied in soil extracts (the term of observation was 8 months). The cultures grown at 20-24 degrees C were found to have the prolonged exponential phase in comparison with that of the cultures grown at 37.5-38.5 degrees C. In the deep litter and the soil under it M. avium remained viable for 10 years.
