Comparison of a beta-lactamase induction test with a test that detects low-frequency resistance to cefotaxime.
A paper strip test that detects cefotaxime-resistant variants of gram-negative bacilli was described and compared with a beta-lactamase induction test. Both tests demonstrated a potential for resistance that is not indicated by standard agar dilution and agar diffusion tests.
