Neonatal sepsis is a blood infection that occurs in an infant younger than 90 days old. Early-onset sepsis is seen in the first week of life. Late-onset sepsis occurs between days 8 and 89.

Causes

A number of different bacteria, including Escherichia coli (E.coli), Listeria, and certain strains of streptococcus, may cause neonatal sepsis.

Early-onset neonatal sepsis most often appears within 24 hours of birth. The baby gets the infection from the mother before or during delivery. The following increases an infant's risk of early-onset sepsis:

•Group B streptococcus infection during pregnancy

•Preterm delivery

•Water breaking (rupture of membranes) that lasts longer than 24 hours before birth

•Infection of the placenta tissues and amniotic fluid (chorioamnionitis)

Babies with late-onset neonatal sepsis get infected after delivery. The following increase an infant's risk of sepsis after delivery:

•Having a catheter in a blood vessel for a long time

•Staying in the hospital for an extended period of time

Symptoms

Infants with neonatal sepsis may have the following symptoms:

•Body temperature changes

•Breathing problems

•Diarrhea

•Low blood sugar

•Reduced movements

•Reduced sucking

•Seizures

•Slow heart rate

•Swollen belly area

•Vomiting

•Yellow skin and whites of the eyes (jaundice)

Exams and Tests

Laboratory tests can help diagnose neonatal sepsis and identify the bacteria that is causing the infection. Blood tests may include:

•Blood culture

•C-reactive protein

•Complete blood count (CBC)

A lumbar puncture (spinal tap) will be done to examine the cerebrospinal fluid for
