Final answer:
The current recommendations depend on whether the infant has early onset or late-onset neonatal meningitis.
Step-by-step explanation:
The current recommendations for a full-term infant who had indications for Group B Streptococcus (GBS) prophylaxis but didn't receive it depend on whether the infant has early onset or late-onset neonatal meningitis. For early onset, intravenous antibiotics should be given to the mother during labor to reduce the risk. For late-onset, infants born to mothers with GBS in the urogenital tract are at a higher risk and may require prophylactic antibiotic treatment. The American Heart Association recommends benzathine benzylpenicillin every 3 or 4 weeks, depending on the patient's risk for reinfection.
