title: Branhamella catarrhalis pneumonia.
abstract: The diagnosis of Branhamella catarrhalis pneumonia in five cases was established by culture of pulmonary secretions obtained by transtracheal aspiration. B catarrhalis caused an acute lobar pneumonia which usually responded promptly to appropriate antimicrobial therapy. Recognition that this organism may cause pneumonia in a nonimmunocompromised person should alert clinicians to consider it as a possible pathogen when Gramnegative diplococci are seen on smears of specimens from the lower respiratory tract.
