Neonatal sepsis.

Neonates are susceptible to infection since several elements of the immune system are deficient. At present, the most common pathogens are Group B streptococci and Escherichia coli. Prolonged rupture of membranes with amnionitis is a high-risk setting. Clinical signs suggesting neonatal sepsis include respiratory distress, poor feeding, hypothermia, seizures and hypotonia. After the sepsis work-up is completed, the initial choice of antibiotics is based on the prevailing organisms and antibiotic sensitivities within the community.
