Final answer:
The Keilhauer-Betke method refers to the Kirby-Bauer method, which is a standardized antimicrobial test to measure the effectiveness of antibiotics against bacteria.
Step-by-step explanation:
The Keilhauer-Betke method seems to be a typo or confusion with the Kirby-Bauer method, which is used for testing the effectiveness of antibiotics against bacteria. This method works by applying antibiotics on a microbial culture and observing the inhibition of bacterial growth. The Kirby-Bauer method, also known as the Kirby-Bauer assay, is pivotal in microbiology and pharmacology for determining the antimicrobial properties of substances. Quantification, metabolic stability estimation, and metabolite identification are other applications of the principles behind the Kirby-Bauer method. Kirby and colleagues, including Bauer, advocated for standardization across laboratories to ensure consistent results, which led to widespread adoption of their namesake assay.
