Assessment of the oxacillin disk screening test for determining penicillin resistance in Streptococcus pneumoniae.

Journal article

The 1 microgram oxacillin disk diffusion screening test was performed on 1516 recent clinical isolates of Streptococcus pneumoniae obtained in a 1994-1995 U.S. surveillance study and the results compared to penicillin MICs determined using a standardized broth microdilution method. The oxacillin disk screening method failed to distinguish penicillin-resistant strains from those that were intermediately susceptible. Furthermore, a high percentage (11.1%) of penicillin-susceptible strains, for ...
