Abstract
Abstract A nutrient medium composition for pathogenic microorganisms, especially for those which cause bacterial infections of the urinary tract, which is characterized in that it consists essentially of definitive chemical compounds, and such conventional nutrient medium components as peptones, meat extracts and yeast extracts are replaced by suitable amounts of aminoacids; the composition is useful for rapidly and simply testing the efficacy of chemotherapeutics against such pathogenic microorganisms with far greater accuracy than heretofore possible.
