[Procedure for preliminary rapid estimation of bacteria susceptibility to chemotherapeutics]. 
Principles and procedure for rapid estimation of bacteria susceptibility to antibiotics on a glucose-tryptone medium with an indicator are described.  The results of the tests with 50 microbial strains of 17 species showed practically complete identity to the results of the antibiograms when the data were estimated in 3-6 hours according to the described procedure in comparison to the findings estimated in 18-24 hours on the standard media.
