Genomic determinants of penicillin G susceptibility and cefazolin inoculum effect in methicillin-susceptible Staphylococcus aureus bloodstream isolates.

BACKGROUND: This study aimed to describe penicillin G susceptibility, blaZ diversity, and genetic determinants of the cefazolin inoculum effect (CfzIE) among MSSA bloodstream isolates. METHODS: The first three non-duplicate MSSA isolates recovered each month from blood cultures a...
