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. Cation-adjusted Mueller Hinton Broth supplemented with 2-5% lysed horse blood is the medium recommended for susceptibility testing of S. pneumoniae.1 Thornsberry and McDougal reported that adding 2% sodium chloride to cation-adjusted Mueller Hinton Broth improved the reliability of MIC tests using oxacillin for detecting methicillin-resistant S. aureus (MRSA).11 In addition, they recommend the alternative direct inoculum standardization procedure (see “Procedure,” step 2) and incubation of the inoculated MIC trays or tubes for a full 24 hours.11, Acid hydrolysate of casein and beef extract provide nutrients for growth of test organisms.
