[Improvement of bacteriological diagnosis of tuberculosis]

The study was undertaken to design a new effective and inexpensive culture medium to be used in the bacteriology of tuberculosis. Replacement of sodium glutaminate by the yeast autolysate S. cerevisie and ammonium citrate--ammonium oxalate in the Finn-II medium, addition of n-alkanes (C12-C18) and potato extract were found to stimulate growth rates and biomass stimulation and to enhance the sensitivity of the medium in the indication of mycobacteria while seeding both laboratory strains and homogenates of biological materials.
