: an underestimated pathogen in brain infection?

is an oral commensal organism belonging to the group (SAG). causes periodontitis as well as invasive, pyogenic infection of the central nervous system, pleural space or liver. Compared with other SAG organisms, has a higher mortality as well as a predilection for intracranial infection, suggesting it is likely to possess virulence factors that mediate specific interactions with the host resulting in bacteria reaching the brain.

A case of penicillin-resistant group B Streptococcus isolated from a patient in the UK.

Objectives: In England, group B streptococci (GBS; Streptococcus agalactiae) are considered universally susceptible to penicillin. Reports from Africa, Asia, North America and a few European countries have described GBS isolates with penicillin MICs above the epidemiological cut-off (0.125 mg/L).

Burden of infant group B disease and impact of maternal screening and antibiotic prophylaxis in Ontario, Canada: a population-based cohort study.

Background: Group B (GBS) significantly contributes to neonatal sepsis and meningitis, with varying disease rates reported globally and limited population-based data. We estimated infant GBS disease burden in Ontario, Canada and assessed the association of maternal GBS screening (35-37 weeks' gestation) and intrapartum antibiotic prophylaxis (IAP) provision with infant disease rates.

Methods: Our population-based cohort study included pregnant individuals and their offspring from April 2012 to March 2018, utilising the provincial birth registry linked to health administrative data.
