| 摘要 |
The invention relates to medicine and to veterinary medicine, and specifically to means for determining the sensitivity of various microorganisms, including bacteria and fungi, to antimicrobial substances. The method for determining the sensitivity of microorganisms to antimicrobial substances comprises taking biological material, incubating microorganisms contained therein on a nutrient medium, introducing an antimicrobial substance to be investigated into the nutrient medium and subsequently assessing the result. A dense, rich nutrient medium is used for cultivating the microorganisms. The antimicrobial substance being investigated is introduced into the nutrient medium prior to cultivation of the microorganisms in a concentration close to the maximum concentration achievable at the location at which the biological material is taken. The sensitivity of the microorganisms to the antimicrobial substance is assessed after the appearance of visible growth of microorganisms in a control culture. Vitamins and/or amino acids, and/or nutritional supplements can be added to the nutrient medium. |
