Abstract:

The accuracy of the published disk diffusion quality control (QC) range for linezolid for Staphylococcus aureus ATCC 25923 has been reported to be problematic, prompting a multicenter study to determine if revision was necessary. Five out of seven laboratories reported values outside the current QC range. Three participants had significant (13.3-60.0%) 'unacceptable' results with zones smaller than the established range. Overall, a range of 21-32 mm was shown (82.4% within the NCCLS published range). A revision (25-31 mm; 95.7% of results) of the QC range is necessary when testing S. aureus ATCC 25923 against linezolid.

Automated Microbial Diagnostics

Automated diagnostic analyzers have transformed clinical microbiology by providing rapid and reliable methods for pathogen identification and antibiotic susceptibility testing. Among these systems, the Vitek 2 is widely used because it automates the traditionally labor-intensive processes of microbial identification (ID) and antibiotic susceptibility testing (AST), delivering standardized and timely results that are essential for effective patient care.Microbial Identification with ID CardsThe...
