Omphalitis is a polymicrobial infection typically caused by a mixture of aerobic and anaerobic organisms.

Associated risk factors include the following:

  • Low birth weight (< 2500 g)

  • Prior umbilical catheterization

  • Septic delivery (as suggested by premature rupture of membranes, nonsterile delivery, or maternal infection)

  • Prolonged rupture of membranes
