BACKGROUND: Pathogenic bacteria have been cultured from the osteomeatal complex (OMC) in one-third of adults with apparent acute bacterial sinusitis; however, it is not known whether bacteria are present in the OMC during uncomplicated viral colds in adults.
METHODS: Adult volunteers were recruited for a study during wellness and at the time of acute common cold. Swab cultures were obtained from the OMC and from the nasopharynx by 2 routes (through the nose and through the mouth). Swab eluates were inoculated on selective agars to detect S. pneumoniae, H. influenzae, and M. catarrhalis.
RESULTS: Bacterial pathogens were detected in the OMC more frequently during common colds than during wellness (31% vs 8%, p < 0.008). Pathogens detected in the OMC were always present in the nasopharynx of the subject.
CONCLUSION: Bacterial pathogens are present in the OMC in a subgroup of adult patients with uncomplicated upper respiratory illness/common cold. The nasopharynx appears to be the reservoir for bacterial pathogens in the OMC.
