Monocyte-macrophage function in the newborn

Analysis of 20 human cord blood samples for monocyte-macrophage function
demonstrates a selective defect in monocyte cellular chemotaxis. Monocyte
bacterial phagocytosis, phagocytosis of paraffin oil particles, and
bacterial killing of staphylococcus 502A were normal when compared with 30
healthy young adult controls. Impaired response of neonatal monocytes to
chemotactants is an additional host defense defect that may help explain
the undue susceptibility of neonates to certain infectious agents.
