Search . It has been suggested that in the treatment of systemic infections, the drug dosage should yield a peak concentration at the site of infection that is two to four times greater than the MIC value, while for urinary tract infections, a peak urine concentration of 10-20 times the MIC value should be achieved.9 However, effective antimicrobial therapy also depends on many other factors.10 Cation-adjusted Mueller Hinton Broth is the medium usually used for dilution antimicrobial susceptibility tests. 3. The interpretation as to whether the organism is susceptible, intermediate, or resistant in its response to the agent is made by comparing the MIC to those in the MIC interpretive standards in CLSI standard M7.1,13 Various factors have been identified as influencing broth dilution susceptibility tests.

Mueller Hinton Broth, not cation-adjusted, has a formula similar to that of the solid medium, but without agar, for use when the fluid medium is preferred. The lowest concentration of antimicrobial agent at which no visible growth occurs is defined as the minimal inhibitory concentration (MIC). The term “microdilution” appeared in the literature in 1970 to describe the minimal inhibitory concentration tests performed with volumes of 0.1 mL or less of antimicrobial solution.5 Correlations between MIC values using microdilution and tube dilution methodologies have been reported to be between 85 and 96%.6,7 The qualitative disc diffusion antimicrobial susceptibility procedure has been standardized since 1966.8 The rationale for an MIC susceptibility test rather than the disc diffusion test is that it gives quantitative information. Heat with frequent agitation and boil for 1 minute to completely dissolve the powder. Mueller Hinton Mh Broth, supplied by Millipore, used in various techniques.

Basically, the Mueller Hinton broth has an identical nutrient formulation with Mueller Hinton agar. After the trays are inoculated, cover with tape or a tight-fitting lid to prevent evaporation. In 1929, Fleming used a serial dilution technique to measure the lowest concentration of penicillin that prevented growth of a test organism in broth.3 Ericsson and Sherris published an excellent review of the various methods for susceptibility testing and the relationship of dilution and diffusion methods.3 Rammelkamp and Maxon were among the earliest to use the tube dilution test to determine the in vitro antimicrobial susceptibility of bacteria isolated from clinical specimens.4 The development of this test resulted from the need to know why some patients infected with S. aureus did not respond to penicillin therapy. 2.
