The authors describe the indications for quantitative susceptibility tests and also the methods themselves (agar dilution, macrodilution, combination tests, tests for beta-lactamase production). This study forms part of a series on susceptibility methods which started with a paper on disk susceptibility testing (this journal, 1984; 114: 1079-1086).
