Stopped: This study would not add any new information
All pregnant women prenatally being followed up or admitted at Rambam HealthCare Campus, Haifa, Israel are potential participants in the study. If a patient is agreeable, the nurse/physician/research coordinator will obtain informed consent. Once informed consent is obtained, the patient can be swabbed for GBS. The swabs will be obtained at the routine follow-up at the clinic at 30, 32 and 35 weeks' gestation. If a patient is found to have a positive GBS culture at 35 weeks, she will receive antibiotic treatment during labour according to the protocol. GBS swabs taken at delivery will be compared to previous swabs taken at an earlier gestational age in order to evaluate sensitivity, specificity, positive and negative predictive values of GBS swabs at each week of gestation and to determine the value of our primary hypothesis.
