Background: Maternal (Group B (GBS)) colonization is an important cause of complications in mothers and neonates during gestation and after delivery. The data regarding GBS colonization among pregnant women in Palestine is scarce. The aim of this study is to determine the prevalence of GBS colonization, its associated risk factors, and the antibiotic sensitivity patterns in Nablus, West Bank, Palestine.
Methods: A cross-sectional, single center study conducted at Rafidia Governmental Hospital in Nablus, West Bank, Palestine. Samples were collected between November 2019 and January 2020. Vaginal swabs from 200 pregnant women (≥35 weeks of gestation) attending the labor and delivery department were plated directly on CHROMagar StrepB (CHROM agar, France) and placed in an incubator at 35-37°C. After 24 and 48 hours, the plates were checked for growth and classified into three categories: growth of GBS with mauve colonies on chromogenic media, no growth, or other growth. The identification of the mauve colonies was confirmed by the CAMP test. Identified GBS isolates were tested for susceptibility to vancomycin, ampicillin, clindamycin, cefotaxime, erythromycin, and levofloxacin using the disc diffusion method. Clinical and demographic information were collected using a questionnaire.
Result: The overall prevalence of GBS colonization was 12%. The median age of the study population was 27 years. GBS colonization was significantly associated with age (=0.013), history of previous preterm delivery (=0.013), and parity (=0.015). No association was noted with smoking, previous abortion, previous history of fetal demise, vaginitis, or urinary tract infection. Resistance to ampicillin, vancomycin, cefotaxime, erythromycin, clindamycin, and levofloxacin was found to be 91.7%, 54.2%, 45.8%, 29.2%, 25%, and 8.3%, respectively.
Conclusion: The prevalence of vaginal GBS in this study was 12% from Nablus, West Bank. Further research is needed to determine the GBS serotypes common in West Bank and the burden they cause on the health system. Moreover, this study also highlights the need to establish a screening program suited to a developing country with low control on the antibiotic's prescription protocols.

Department of Pediatrics, University of Pittsburgh School of Medicine, Pittsburgh, USA.
This review summarizes key virulence factors associated with group B (GBS), a significant pathogen particularly affecting pregnant women, fetuses, and infants. Beginning with an introduction to the historical transition of GBS from a zoonotic pathogen to a prominent cause of human infections, particularly in the perinatal period, the review describes major disease manifestations caused by GBS, including sepsis, meningitis, chorioamnionitis, pneumonia, and others, linking each to specific virulence mechanisms. A detailed exploration of the genetic basis for GBS pathogenicity follows, emphasizing the roles of capsules in pathogenesis and immune evasion.

Background: Group B Streptococcus (GBS) colonization is one of the major causes of severe neonatal infections. The study was intended to identify GBS colonization in pregnant women, explore its potential risk factors, and analyze the impact of GBS on outcomes for both mothers and newborns.
Material And Methods: A retrospective research was carried out on pregnant women who had undergone GBS screening and delivered from June 2020 to December 2022.

Background: Group B streptococcus (GBS) colonization in pregnant women is associated with adverse perinatal outcomes, including stillbirth. This meta-analysis investigated the relationship between maternal rectovaginal GBS colonization and the risk of stillbirth.
Methods: We conducted a comprehensive literature search across several databases, including PubMed, Embase, Web of Science, Wanfang, and China National Knowledge Infrastructure, covering studies published from the inception of the database until September 9, 2024.

Article Synopsis
- Group B streptococcus (GBS) is a significant cause of infections in neonates and pregnant women, with Japan implementing guidelines for screening and antibiotic use, yet infections have not decreased significantly.
- Approximately 15% of pregnant women lack GBS screening, and issues like intermittent colonization lead to early-onset disease; current preventative measures don't address increasing cases of late-onset disease.
- This study found that using polymerase chain reaction for GBS detection was more effective than culture methods, highlighted the risk of horizontal transmission, and emphasized the need for better diagnostic tools and potential maternal vaccination for prevention.

To understand the colonization status of Group B Streptococcus (GBS) in the reproductive tract of pregnant women in the Linyi region, the drug resistance, genotype distribution, and molecular epidemiological characteristics of GBS, and to explore the high-risk factors for GBS infection in late-stage pregnant women. A total of 3269 pregnant women at 35-37 weeks of gestation who visited the Obstetrics Department of Linyi Maternal and Child Health Hospital from January 2019 to December 2021 were selected as the study subjects. Vaginal and rectal swabs were collected for GBS culture.
