Algorithms and Tables

Revised Guidelines for the Prevention of Perinatal Group B Streptococcal (GBS) Disease were recently released from CDC. These 2010 guidelines were developed using an evidence-based approach in collaboration with several professional associations.*

Below are printable algorithms and tables from the 2010 guidelines.

Intrapartum Antibiotic Prophylaxis

• Algorithm for screening for group B streptococcal (GBS) colonization and use of intrapartum prophylaxis for women with preterm labor (PTL) [1 page].
• Algorithm for screening for group B streptococcal (GBS) colonization and use of intrapartum prophylaxis for women with preterm premature rupture of membranes (pPROM). [1 page]
• Algorithm for recommended regimens for intrapartum antibiotic prophylaxis for prevention of early-onset group B streptococcal (GBS) disease [1 page].
• Indications and nonindications for intrapartum antibiotic prophylaxis to prevent early-onset group B streptococcal (GBS) disease [1 page].

Secondary Prevention Among Newborns

• Algorithm for secondary prevention of early-onset group B streptococcal (GBS) disease among newborns [1 page].

Clinical Specimens and Laboratory Testing

• Algorithm for recommended laboratory testing for prenatal screening for group B streptococcal (GBS) colonization [1 page].
• Procedures for collecting clinical specimens for culture of group B Streptococcus (GBS) at 35–37 weeks’ gestation [1 page].
• Procedures for processing clinical specimens for culture of group B Streptococcus (GBS) [1 page].
• Procedures for clindamycin and erythromycin susceptibility testing of group B streptococcal (GBS) isolates, when ordered for penicillin-allergic patients [1 page].
• Identification of group B Streptococcus (GBS) bacteriuria in pregnant women [1 page].
