The results of the testing are reported as a table, sometimes called an antibiogram. Bacteria are marked as sensitive, resistant, or having intermediate resistance to an antibiotic based on the minimum inhibitory concentration (MIC), which is the lowest concentration of the antibiotic that stops the growth of bacteria. The MIC is compared to standard threshold values (called "breakpoints") for a given bacterium and antibiotic. Breakpoints for the same organism and antib… WebThe most probable number (MPN) technique is used to detect the number of microorganisms from foods, especially when the number of microorganisms is less than … Web• The MIC number is the lowest concentration (in μg/mL) of an antibiotic that inhibits the growth of a given strain of bacteria.
