An improved clinical prediction rule for identifying neonatal bacterial meningitis: a multicenter cohort study. Finally, the new algorithm for secondary prevention of early-onset group B streptococcal disease in newborns should be applied to all infants, not only those at high risk of infection. Patients who are allergic to penicillin should be evaluated for anaphylaxis risk. The key changes in the 2010 guidelines include the following: • expanded recommendations on laboratory methods for the identification of GBS, • clarification of the colony-count threshold required for reporting GBS detected in the urine of pregnant women, • updated algorithms for GBS screening and intrapartum chemoprophylaxis for women with preterm labor or preterm premature rupture of membranes, • a change in the recommended dose of penicillin-G for chemoprophylaxis, • updated prophylaxis regimens for women with penicillin allergy, and • a revised algorithm for management of newborns with respect to risk for early-onset GBS disease.

Group B streptococci at delivery: high count in urine increases risk for neonatal colonization. McKenna DS, eCollection 2020. If the organism is susceptible to clindamycin and resistant to erythromycin, it should be tested for inducible clindamycin resistance with the double-disk diffusion test, because erythromycin-resistant isolates can induce resistance to clindamycin. Fifth, the guideline provides new recommendations about antibiotic regimens for women with penicillin allergy. Zywicki SS, Centers for Disease Control and Prevention. 2000;105(1 pt 1):21–26. Fajardo K. corrected] For those at serious risk of anaphylaxis, clindamycin is recommended if the organism is susceptible, and vancomycin is recommended if there is clindamycin resistance or if susceptibility is unknown. Thus, group B streptococcal bacteriuria at any point in pregnancy is an indication for intrapartum chemoprophylaxis. The previous CDC guideline recommended that any amount of group B streptococcal bacteriuria be considered a positive culture.5 The new guideline reflects findings that only concentrations exceeding 104 colony-forming units per mL are associated with early-onset neonatal disease.9 As a result, the new guideline recommends that laboratories report a urine specimen positive for GBS when the organism is present at concentrations of at least 104 colony-forming units per mL, whether GBS is present as a single isolate or if there is another organism present.1.
