The aim of this commentary is to describe changes in women care at an obstetric department that made it possible to reduce the number of beds from 40 to 29. Patient pathways were reviewed and revised using lean methodology. The mean length of stay was reduced from 70 to 59 hours and the mean numbers of hospitalizations per woman from 1.26 to 1.20. At the organizational level, we introduced a Family Department, home management of newborns, home monitoring of the women with cardiotocography and blood samples, and intrapartum Group B Streptococcus-PCR...

Group B Streptococcus (GBS) clinical isolates with reduced penicillin susceptibility (PRGBS) have emerged through acquisition of amino acid substitutions in penicillin-binding protein 2X (PBP2X). Moreover, we also reported the emergence of penicillin-susceptible GBS clinical isolates with reduced ceftibuten susceptibility (CTBr PSGBS) due to amino acid substitutions in PBPs. However, whether or not these amino acid substitutions are responsible for the reduced ceftibuten susceptibility (RCTBS) profile remains unclear...

Group B Streptococcus (GBS) colonizes the gastrointestinal and urogenital tracts of approximately 30% of women, and it can cause sepsis and meningitis in neonates. GBS has been shown to form biofilms in vitro, but the effects of environmental and genotypic factors upon GBS biofilm formation are unclear. The aim of the present study was to optimize culture conditions for enhanced GBS biofilm production. Furthermore, this study also investigated the influences of strain lineage, pilus profile, and isolation source on GBS biofilm formation...

BACKGROUND: The recommendation of the U.S. Centers for Disease Control and Prevention regarding universal screening for Group B Streptococcus (GBS) at 35-37 weeks gestational age in pregnancy is not accepted in Israel. The National Council for Obstetrics, Neonatology and Genetics recommends intrapartum prophylaxis, mainly based on risk factors, to prevent early neonatal GBS infection. This policy is based on past studies demonstrating low colonization rates of the bacteria in Israeli pregnant women and very low neonatal sepsis rates...

Group B Streptococcus (GBS) carriage by pregnant women is the primary risk factor for early-onset GBS neonatal sepsis. Intrapartum antibiotic prophylaxis (IAP) can prevent this transmission route, and two main approaches are recommended to base the selection of pregnant women to be submitted to IAP: the risk-based and the culture-based strategies. In Brazil, compliance to such recommendations is poor, and not much is known about GBS carriage. In the present study, 3,647 pregnant women living in Rio de Janeiro State, Brazil, were screened for GBS anogenital colonization, over a period of 8 years (2008-2015)...

BACKGROUND: Implementing matrix assisted laser desorption ionization time of flight (MALDI-TOF) and multiplex PCR (mPCR) has been associated with decreased mortality and hospital length of stay in adults, but the impact in pediatrics is less understood. METHODS: This pre-post quasi-experimental study compared antibiotic prescribing for positive blood cultures in patients ≤21 years collected in 2012 (pre-intervention) and in 2015 (after MALDI-TOF/mPCR). Time to effective and optimal antimicrobial therapy were evaluated using Cox proportional hazards regression...

Group B streptococcus (GBS) is a leading cause of serious bacterial neonatal infections worldwide, which provides an unmet medical need for a globally effective vaccine. The recombinant GBS fusion antigen GBS-NN contains the N-terminal regions of the GBS Rib and Alpha C proteins. It shows promising immunogenicity eliciting protective immunity in mice and encouraging results in early human clinical trials. Understanding the physical stability of GBS-NN containing conformational B-cell epitopes is crucial to ensure optimal vaccine stability, efficacy and safety...

Antigenic diversity of the M protein is a major constraint to the development of immunity to group A streptococcus (GAS). We demonstrate that a conserved cryptic epitope that is unrecognized by the host immune system following infection can protect mice following vaccination, and that immunity is strengthened and broadened following successive infections. The observation that infection can boost and broaden, but cannot prime immunity to a cryptic epitope, may be exploited for vaccines for other pathogens.

BACKGROUND & AIMS: Colorectal cancer (CRC) development has been associated with increased proportions of Bacteroides fragilis and certain Streptococcus, Fusobacterium, and Peptostreptococcus species in the intestinal microbiota. We investigated associations between bacteremia from specific intestinal microbes and occurrence of CRC. METHODS: We performed a retrospective study, collecting data from13,096 adult patients (exposed group) in Hong Kong hospitalized with bacteremia (identified by blood culture test), without a previous diagnosis of cancer, from January 1, 2006 through December 31, 2015...

BACKGROUND: Group B Streptococcus (GBS) is the leading cause of septicemia, meningitis, and pneumonia in neonates. Maternal colonization with GBS is the principal risk factor for early-onset disease in infants. Group B Streptococcus is now an important cause of maternal and neonatal morbidity and mortality in many parts of the world. In Ethiopia, few studies have been done on GBS colonization among pregnant women. The aim of this study was to determine the prevalence of GBS colonization, antimicrobial susceptibility patterns and assess risk factors among pregnant women...

Streptococcus agalactiae, or group B streptococcus (GBS), is an important pathogen as it is the leading cause of neonatal deaths due to sepsis, meningitis or bacterial pneumonia. Although the development of an effective and safe GBS vaccine is on the agenda of many research labs, there is no GBS vaccine on the market yet. In the present study we attempted to engineer a live vaccine strain based on Bac, a surface protein of GBS, incorporated into a surface fimbrial protein of probiotic Enterococcus. The resulting strain induced specific systemic and local immune responses in mice and provided protection against GBS when administered via the intranasal, oral or intravaginal immunization routes...

BACKGROUND: Streptococcus agalactiae or Group B Streptococcus (GBS) remains the leading cause of infections in newborns worldwilde. Prenatal GBS screening of pregnant women for vaginal-rectal colonization is recommended in many countries to manage appropriate intrapartum antimicrobial prophylaxis for those identified as carriers. In this study, a novel melting-curve based multiplex real-time PCR assay for the simultaneous detection of GBS and macrolide and lincosamide resistance markers was developed...

Streptococcus pyogenes (group A Streptococcus) causes diseases ranging from mild pharyngitis to severe invasive infections. The N-terminal fragment of Streptococcal M protein elicits protective antibodies and is an attractive vaccine target. However, this N- terminal fragment is hypervariable and there are more than 200 different M types. We are developing an intranasal live bacterial vaccine comprised of 10 strains of Lactococcus lactis, each expressing one N-terminal fagment of M protein. Live bacterial-vectored vaccines have lower associated costs because of its less complex manufacturing processes compared to protein subunit vaccines...

BACKGROUND: Many vaccines contain multiple components. Licensed pneumococcal conjugate vaccines (PCV) contain polysaccharides from 7, 10, or 13 different serotypes of Streptococcus pneumoniae. The main outcomes in randomised trials of pneumococcal vaccines are serotype-specific antibody measures. Comparisons are made between groups for each serotype, resulting in multiple separate comparisons of treatment effects which can be complicated to interpret. We investigated methods for computing the overall difference between vaccine groups across all serotypes...

Coevolution of the human host and its associated microbiota has led to sophisticated interactions to maintain a delicate homeostasis. Emerging evidence suggests that in addition to small molecules, peptides, and proteins, small regulatory noncoding RNAs (sRNAs) might play an important role in cross-domain interactions. In this study, we revealed the presence of diverse host transfer RNA-derived small RNAs (tsRNAs) among human salivary sRNAs. We selected 2 tsRNAs (tsRNA-000794 and tsRNA-020498) for further study based on their high sequence similarity to specific tRNAs from a group of Gram-negative oral bacteria, including Fusobacterium nucleatum, a key oral commensal and opportunistic pathogen...
