[Development of a method for the quantitative assessment of microorganism sensitivity to antibiotics using discs. The study of different nutrient media for determining microorganism sensitivity to antibiotics].

Five nutrient media used for determination of microbial sensitivity to antibiotics, i.e. beaf-peptone agar, Hottinger pancreatic beaf infusion agar, sprat hydrolysate nutrient agar of the Dagestan Research Institute of Nutrient Media, Muller-Chintone agar from Bulgaria and "Oxoid" agar for determination of microbial sensitivity were studied comparatively. The media were compared with respect to the growth density with the use of different test-cultures and the clearance of the inhibition growth zones around the discs containing different antibiotics. The best results were obtained with the use of sprat hydrolysate nutrient agar. Further studies on the medium standardization are necessary.
