Clinical study on bacteria detected in the upper and lower respiratory tracts in patients with sinobronchial syndrome.
The authors examined bacteria to confirm the pathogenesis of sinobronchial syndrome (SBS). There were several theories such as the pus-descending, the pus-ascending, the coinciding theory and so on. Detection of bacteria was performed in SBS patients, empyema patients with no lower respiratory disease, and healthy adults. Considering SBS bacteriologically from the obtained results, the authors consider that internal infections of aerobic gram-negative bacteria of the normal flora mainly including Haemophilus influenzae possibly develop in two directions, downward and upward (into nasal cavities) from the pharynx, and so the pathogenesis of SBS might not be explained satisfactorily by either the ascending or the descending theory alone.
