Neonates have a high antibiotic consumption because of their susceptibility for bacterial infections. Since the early diagnosis of bacterial infection in neonates is difficult, intravenous broad-spectrum antimicrobial therapy is usually started promptly after subtle symptoms. The majority of neonates become asymptomatic shortly after initiation; when infection is probable or proven by elevated inflammatory markers and/or a positive blood culture, intravenous antibiotics are administered for at least 7 days.
