A multiplex PCR assay for the detection of respiratory bacteriae in nasopharyngeal smears from children with acute respiratory disease
To elucidate the frequency of infections with pathogenic respiratory bacteriae during an inter-epidemic period a multiplex PCR assay was used to screen nasopharyngeal smears for the presence of DNA specific for Bordetella pertussis, Bordetella parapertussis, Chlamydophila pneumoniae and Mycoplasma pneumoniae. 187 samples from children aged 2-14 y were analysed with this method in addition to classical bacteriology and compared to results obtained with commercially available PCR kits for each single parameter. From 82 samples positive by bacteriology, 8 (4.3%) were also positive by PCR, whereas from 105 negative samples, 12 (6.4%) were positive only by PCR. From the total of 20 samples positive by PCR, 4 were found to be positive for M. pneumoniae, 6 for B. pertussis, 3 for B. parapertussis and 7 for both B. pertussis and B. parapertussis. Multiplex PCR is a very useful approach for the diagnosis of bacterial infections not detectable by classical bacteriology. In some patients, PCR was the only method giving a positive result, and in others double infections were diagnosed only because of the PCR contribution. Combination of classical bacteriology with multiplex PCR allows a precise diagnosis of infections in the upper respiratory tract, resulting in a more effective therapy.
