Despite major advances in the management and care of critically ill and low‐birthweight human and nonhuman primate infants over the past two decades, infection remains a major source of neonatal morbidity and mortality. Although the causes of enhanced susceptibility and dissemination of neonatal infections are incompletely defined in the literature, substantial evidence from this and other laboratories has implied that functional abnormalities of neonatal polymorphonuclear leukocytes (PMNs) may be a major contributor. Increased understanding of the functional characteristics of neonatal PMNs should, therefore, provide significant insight into the pathogenesis and possible therapy of infections in neonates. Our laboratory has been actively involved in evaluating the functional competence of PMNs in neonatal human and nonhuman primates. This report describes a study in which we have confirmed and characterized the functional compromises in neonatal PMNs of rhesus monkeys, including deficiencies in chemotaxis, membrane deformability, phagocytosis, and killing.
