Streptococcus agalactiae (Group B Streptococcus, GBS) causes life-threatening infections in newborns and adults with chronic medical conditions. Serotype IV strains are emerging both among carriers and as cause of invasive disease and recent studies revealed two main Sequence Types (STs), ST-452 and ST-459 assigned to Clonal Complexes CC23 and CC1, respectively. Whole genome sequencing of 70 type IV GBS and subsequent phylogenetic analysis elucidated the localization of type IV isolates in a SNP-based phylogenetic tree and suggested that ST-452 could have originated through genetic recombination. SNPs density analysis of the core genome confirmed that the founder strain of this lineage originated from a single large horizontal gene transfer event between CC23 and the hypervirulent CC17. Indeed, ST-452 genomes are composed by two parts that are nearly identical to corresponding regions in ST-24 (CC23) and ST-291 (CC17). Chromosome mapping of the major GBS virulence factors showed that ST-452 strains have an intermediate yet unique profile among CC23 and CC17 strains. We described unreported large recombination events, involving the cps IV operon and resulting in the expansion of serotype IV to CC23. This work sheds further light on the evolution of GBS providing new insights on the recent emergence of serotype IV.

Unlabelled: The BioFire FilmArray meningitis/encephalitis panel (MEP) was brought to the University of Kentucky in 2016 to aid in the identification of community-acquired meningitis and encephalitis (ME). This panel has shown variable performance with some institutions showing high sensitivity and specificity for many pathogens but others seeing false positives during clinical use. We evaluated the panel's performance using retrospective chart review of patients at the University of Kentucky from October 2016 to September 2022, including 7,551 MEP results.

Background: Streptococcus agalactiae poses a significant threat to neonatal health, causing morbidity and mortality when transmitted from the maternal vagina to the newborn's respiratory tract. Among its various strains, serotype III is predominant in severe neonatal infections in Asia. However, the mechanisms of pathogenesis and host responses underlying serotype-specific disease outcomes remain poorly understood.

Bacterial meningitis causes significant morbidity and mortality in infants. Lumbar punctures are often deferred until the results of blood cultures are known and sometimes not considered, making this population susceptible to a missed diagnosis. There are few studies describing the epidemiology of neonatal meningitis in quaternary neonatal intensive care unit settings.

Group B Streptococcus is a bacterium that colonizes in approximately 20% of pregnant women and can be vertically transmitted to newborns, leading to maternal-neonatal adverse outcomes, such as chorioamnionitis, neonatal sepsis, and pneumonia. However, there is currently no agreement on the optimal induction method for this specific population. This study aims to evaluate the safety of a single balloon catheter (BC) in comparison to dinoprostone for labor induction in term pregnant women with group B Streptococcus colonization.

Background: Group B Streptococcus (GBS) bacteremia in nonpregnant adults is of increasing concern, particularly among the elderly in underlying conditions. This study analyzed the serotype distribution, antimicrobial resistance patterns, and clinical characteristics of GBS bacteremia in nonpregnant adults over a 15-year period in two tertiary hospitals in Korea.
Methods: From 2007 to 2021, patients aged ≥ 19 years with GBS bacteremia were identified via retrospective electronic medical record review.
