Final answer:
The antibiotics for GBS intrapartum are mainly ß-lactam antibiotics like penicillin or ampicillin; in cases of allergy cefazolin, clindamycin or vancomycin may be used.
Step-by-step explanation:
Treatment of Group B Streptococcus (GBS) Intrapartum:
The antibiotics that provide adequate coverage for GBS intrapartum mainly include ß-lactam antibiotics, such as penicillin or ampicillin. During labor these antibiotics are administered intravenously to prevent the transmission of GBS from mother to infant. In cases of penicillin allergy, alternatives like cefazolin clindamycin or vancomycin can be used depending on the sensitivity of the GBS strain.
For neonates with GBS infection, such as neonatal meningitis, treatment often involves the combination of intravenous ampicillin with an aminoglycoside such as gentamicin. It is crucial to begin treatment promptly to reduce the risk of serious complications or mortality.
