Co-colonization by Haemophilus influenzae with Streptococcus pneumoniae enhances pneumococcal-specific antibody response in young children.

Vaccine.

Streptococcus pneumoniae (Spn), Haemophilus influenzae (Hi) and Moraxella catarrhalis (Mcat) are common bacterial pathogens of respiratory infections and common commensal microbes in the human nasopharynx (NP). The effect of interactions among theses bacteria during co-colonization of the NP on the host immune response has not been evaluated. The objective of this study was to assess the impact of co-colonization by Hi or Mcat on the systemic antibody response to vaccine protein candidate antigens of Spn and similarly the impact of co-colonization by Spn and Mcat on antibody responses to Hi vaccine protein candidate antigens.
