The document discusses methods for examining new antibiotics by way of microbiological assays. It describes how the least inhibitory concentration (MIC) is usually identified working with both liquid or good dilution methods. The liquid dilution method requires starting a series of take a look at tubes with doubling dilutions in the antibiotic becoming analyzed and incubating by using a exam microorganism.
