Serum factors for opsonisation of non-typable Haemophilus influenzae.
Neutrophil chemiluminescence was used to assess the opsonins required for phagocytosis of non-typable Haemophilus influenzae isolated from sputum samples of patients with hypogammaglobulinaemia. Immunoglobulin was the major opsonin, whereas complement was relatively unimportant. Evidence was found for a heat-labile opsonin other than complement that enhanced phagocytosis of these organisms. Tuftsin was shown to aid phagocytosis of H. influenzae without triggering chemiluminesence.
