“…The explanation for this phenomenon appears to be complex, involving both an incomplete development of the neutrophil system (8,14,16,23,24) and lack of type-specific antibodies to major bacterial pathogens (2,15,21). It is well recognized that because of these deficiencies, many neonates who contract bacterial sepsis cannot be saved with standard antibiotic therapy alone; therefore, much attention has been paid to additional, adjunctive measures, such as exchange transfusion (3 1,32), neutrophil transfusion (9,10,19,20,33) and plasma/antibody administration (28,30) in order to improve the outcome of these patients.…”
