E test: a novel technique for antimicrobial susceptibility testing.

Abstract

We describe the applicability of the E test (AB Biodisk Solna, Sweden), a new method for determining minimum inhibitory concentrations of antimicrobial agents against bacteria. This report is based on the literature review and on our own experience using the E test for susceptibility testing of the Xanthomonas maltophilia, Streptococcus pneumoniae and Streptococcus viridans group against eight different drugs.
