ETEST ANTIMICROBIAL SUSCEPTIBILITY TESTING - POLYMYXIN B

Reason

Following a study conducted on ETEST Polymyxin B with 180 clinical strains (Pseudomonas aeruginosa, Acinetobacter and Enterobacteriaceae), an underestimation of the Minimum Inhibitory Concentration (MIC) has been observed for Pseudomonas aeruginosa and Acinetobacter species, compared to those obtained using the Broth Micro-Dilution (BMD) reference method. This has led to false susceptible results when the ETEST Polymyxin B results are interpreted using the Clinical and Laboratory Standards Institute (CLSI) breakpoints
