Classification of group B streptococci with reduced β-lactam susceptibility (GBS-RBS) based on the amino acid substitutions in PBPs.
All clinical isolates of group B Streptococcus (GBS; Streptococcus agalactiae) are considered uniformly susceptible to β-lactams, including penicillins. However, GBS with reduced penicillin susceptibility (PRGBS) were first identified by our group in Japan and have also been reported from North America. PRGBS are non-susceptible to penicillin because of acquisition of amino acid substitutions n...

coding regions of the transpeptidase domain of the pbp1a, pbp2b and pbp2x genes of the two GBS isolates were amplified and sequenced according to previously outlined methods. 4 Amino acid sequences were deduced and analysed using the ClustalW alignment tool included in the Lasergene software (DNAstar, Madison, WI, USA). Nucleotide and deduced amino acid sequences were compared with those of the...
