ABSTRACT
The aetiology and microbial flora of nasal polyps is not well understood. No study in the literature has reported an association between the sub-bacterium Mycoplasma pneumoniae and nasal polyps. We have developed an assay method using the Polymerase Chain Reaction (PCR) to amplify a specific region of the M. pneumoniae DNA in extracts of clinical samples using species-specific primers designed to a region of the 16S rRNA. The presence of M. pneumoniae was detected in 13/14 (93%) nasal polyps, in 4/5 (80%) rhinosinusitis mucosal samples but only in 1/7 (14%) of control samples (obstructive turbinates). An epidemic of infections due to M. pneumoniae is expected to occur in 1995. We believe this assay could form the basis of a rapid technique for M. pneumoniae detection. We also propose that the presence of M. pneumoniae may be of importance in the aetiology of nasal polyps.
