Abstract

The adherence of Bordetella pertussis to respiratory cilia and its survival in neutrophils and macrophages is crucial to the pathogenesis of whooping cough. To investigate the role of endogenous interferon (IFN)-γ in acute infection, levels of IFN-γ in bronchoalveolar lavage (BAL) fluid of mice infected intranasally with B. pertussis were determined. Since pertussis toxin is released during infection by B. pertussis either locally or systemically, serum levels of IFN-γ in mice injected intravenously with pertussis toxin were also determined. A persistent and significant increase of IFN-γ levels with concomitant peripheral blood lymphocytosis was observed after 5 and 10 days. The results of this study showed an early but transitory production of endogenous IFN-γ in BAL fluid of mice infected with B. pertussis.
