The capacity of the DIRAMIC system to detect strains producing extended-spectrum-betalactamase (ESBL) was evaluated through the comparison with two phenotypic confirmatory tests: double-disk synergy test and E-test. Ninety seven clinical isolates of Escherichia coli y Klebsiella spp. previously characterized; not repeated and suspected of being ESBL producers were studied by the three methods. In comparison with E-test and double-disk synergy test, DIRAMIC system showed a sensitivity of 85.7% and 92.7% as well as specificity of 100% and 92...
