title: [Comparative study of mycoplasmae and stable L-forms of bacteria].
abstract: A comparative study of mycoplasmae and L-form bacteria was carried out. Both of them were well passaged on a special nutrient medium with the addition of thallium acetate, i.e. they were resistant to this factor. But, in difference from the L-form bacteria, mycoplasmae failed to be passaged on the serum-free medium; the cultures of the L-form bacteria were highly resistant to the action of osmotic stabilizers and to the pressure of the nutrient medium of 15 and 30 atm; as to mycoplasmae--they perished at such a high pressure. The majority of mycoplasmae were resistant to the action of osmotic shock, and L-form bacteria lost their viability in distilled water as soon as in 2 hours.
