[Comparative study of mycoplasmae and stable L-forms of bacteria]. / Sravnitel'noe izuchenie mikoplazm i stabil'nykh L-form bakterii

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.

[Isolation of Mycoplasma from the urine of patients with chronic pyelonephritis]. / Vydelenie mikoplazm iz mochi bol'nykh khronicheskim pielonefritom

Bacteriological analysis of urine of 150 patients with chronic pyelonephritis was performed. As a result mycoplasma was isolated from urine of 25 patients. Mycoplasma and Coli bacteria or Proteus were isolated simultaneously from urine of 10 patients. Biochemical properties and sensitivity to antibiotics of 9 isolates were studied. The data provided recommendation of the urine analysis for the presence of mycoplasma.
