• In utero transplacentally or through ruptured membranes

• In the birth canal during delivery (intrapartum)

• From external sources after nascency (postpartum)

Neonatal infections with herpes simplex viruses, HIV, hepatitis B, group B streptococci, enteric gram-negative organisms (primarily Escherichia coli), Listeria monocytogenes, gonococci, and chlamydiae usually occur from passage through an infected birth canal. Sometimes ascending infection tin can occur if delivery is delayed subsequently rupture of membranes.

Maternal IgG antibodies are actively transported across the placenta, but constructive levels for all organisms are not achieved until nearly term. IgM antibodies do not cross the placenta. Premature infants have decreased intrinsic antibody production and reduced complement activity. Premature infants are besides more likely to require invasive procedures (eg, endotracheal intubation, prolonged 4 access) that predispose to infection.

Symptoms and Signs of Neonatal Infections

Symptoms and signs of infection in neonates tend to be nonspecific (eg, airsickness or poor feeding, increased sleepiness or languor, fever or hypothermia, tachypnea, rashes, diarrhea, intestinal distention). Many built infections acquired earlier birth tin can cause or be accompanied past diverse symptoms or abnormalities (eg, growth brake, deafness, microcephaly, anomalies, failure to thrive, hepatosplenomegaly, neurologic abnormalities).
