The genetic diversity of group B Streptococcus in young, nonpregnant women is not well studied. Application of multilocus sequence analysis to 85 group B Streptococcus strains recovered from college students revealed similarities and differences in distribution of group B Streptococcus lineages, compared with that of previously studied pregnant populations, and revealed that strains of 1 clone ...

Group B Streptococcus (group B Strep or GBS) is the UK's commonest cause of severe early-onset (up to six days) infection in babies. GBS is a normal body commensal, colonising the gut and vagina. GBS may pass to babies around childbirth; although most are unaffected, some develop severe infection. GBS is also a recognised cause of stillbirth and puerperal sepsis. Most GBS infection in babies is...

Sir, Antibiotic resistance in the group B Streptococcus (GBS) is not widely appreciated and many clinical laboratories do not undertake full antibiotic susceptibility tests of clinical isolates. However, antibiotic combinations such as a penicillin plus gentamicin are often used to manage severe GBS infection , exposing patients to enhanced risk of antibiotic-related toxicity whilst attempting ...

We report a case of bacterial endocarditis caused by nonhemolytic group B streptococcus (GBS) in a 67-year-old man with no predisposing risk factors. Nonhemolytic GBS strains rarely cause illness and are usually detected in perinatal infections. We believe this to be the first reported case of endocarditis caused by a nonhemolytic strain of GBS.

Traditionally, the capsular polysaccharide (CPS) antigen has been used to distinguish between the nine known serotypes of group B streptococcus (GBS) by classical antibody-antigen reactions. In this study, we used PCR for all CPSs and selected protein antigens, multilocus sequencing typing (MLST), and pulsed-field gel electrophoresis (PFGE) to molecularly characterize 92 clinical isolates ident...

Group B Streptococcus (GBS) is a pathogen that has developed some strategies to resist host immune defenses. Because phagocytic killing is an important pathogenetic mechanism for bacteria, we investigated whether GBS induces apoptosis in murine macrophages. GBS type III strain COH31 r/s (GBS-III) first causes a defect in cell membrane permeability, then at 24 h, apoptosis. Apoptosis was confirm...
