Background: Maternal Group B (GBS)/ colonization rates vary worldwide; however, no such recent data are available from the United Arab Emirates (UAE).
Objective: The objective of this study was to determine the prevalence of GBS colonization among pregnant women attending an antenatal clinic of a hospital in Ras Al Khaimah, UAE, along with the antibiotic sensitivity pattern, the clinical profile and pregnancy (maternal and fetal) outcome.
Methods: This prospective observational study routinely offered rectovaginal swab for GBS to all women attending the antenatal clinic at 35-37 weeks of pregnancy between January and December 2019. MASTASTREP kit and Vitek-2 identification system was used for culture and identification. Women with positive cultures were followed up for any maternal and neonatal complications and the use of intrapartum antibiotic prophylaxis (IAP).
Results: A total of 2295 women were included, of which 158 (6.9%) had positive cultures for GBS colonization. The carriage rate was higher in women without any risk factors for early-onset GBS disease (EOGBS) ( < 0.01). The GBS isolates were about 97% susceptible to linezolid and vancomycin, 90% to benzyl penicillin and 95% to ampicillin. Resistance to trimethoprim/sulfamethoxazole, clindamycin, erythromycin, and levofloxacin were about 77%, 57%, 57%, and 10%, respectively. Urinary tract infection in GBS colonized women were more common in those aged ≤30 years ( = 0.009). Fetal outcome was favorable in women receiving IAP for GBS colonization. No neonate had culture proven EOGBS.
Conclusion: The prevalence of GBS colonization in pregnant women as well as the overall maternal and neonatal complications is low in Ras Al Khaimah, UAE. IAP is effective in preventing early-onset sepsis in newborn, and thus should be initiated in those with GBS colonization. The cultured GBS showed sensitivity to most antibiotics.

Prospective study of peripartum group B streptococcus colonization in Japanese mothers and neonates.

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.
Genotype Distribution and High-Risk Factors Analysis of Group B Streptococcus in Late-Stage Pregnant Women in the Linyi Region.

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.

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: Maternal colonization with Group B Streptococcus (GBS) disrupts the vaginal microbiota, potentially affecting infant microbiota assembly and growth. While the gut microbiota's importance in infant growth is recognized, the specific effects of maternal GBS on growth remain unclear. This study aimed to explore the effects of maternal vaginal GBS during pregnancy on early infant growth, microbiome, and metabolomics.

Background: Significant disparities in Group B Streptococcus (GBS) colonisation and neonatal disease rates have been documented across different geographical regions. For example, Bangladesh reports notably lower rates compared to the United Kingdom (UK) and Malawi. This study investigates whether this epidemiological variability correlates with the immune response to GBS in these regions.
