Evaluation of disk approximation and single-well broth tests for detection of inducible clindamycin resistance in Streptococcus pneumoniae.

摘要

This study evaluated an agar disk diffusion D-zone test and an erythromycin-clindamycin (ERY + CLI) single-well broth test for inducible CLI resistance in Streptococcus pneumoniae. The standard CLSI disk approximation test and a single-well combination test incorporating 1 plus 0.5 mug/ml ERY + CLI detected >96 of isolates containing the ermB determinant.
