Practical Disk Diffusion Test for Detecting Group B Streptococcus with Reduced Penicillin Susceptibility

8 Oct 2009

Abstract excerpt

Although group B streptococcus (GBS) has been considered to be uniformly susceptible to beta-lactams, the presence of GBS with reduced penicillin susceptibility (PRGBS) was recently confirmed genetically. We developed a feasible and reliable method for screening PRGBS in clinical microbiology laboratories using a combination of ceftibuten, oxacillin, and ceftizoxime disks.
