RT Journal Article SR Electronic T1 Antibacterial chemotherapy in the newborn JF Drug and Therapeutics Bulletin JO Drug Ther Bull FD BMJ Publishing Group Ltd SP 13 OP 16 DO 10.1136/dtb.19.4.13 VO 19 IS 4 YR 1981 UL http://dtb.bmj.com/content/19/4/13.abstract AB The newborn is immunologically immature and at risk of infection. Bacterial infection is usually acquired during or soon after birth, rather than in utero. Preterm and low-birth-weight babies are at special risk; prolonged rupture of the membranes, maternal infection, and difficulties in delivery all increase the risk of infection.
