Validation of a new seminested PCR-based detection method for Legionella pneumophila.
We report a new seminested PCR method for detection of Legionella pneumophila based on the simultaneous amplification of a 387 bp fragment of the dotA gene and a 827 bp recombinant fragment that serves as an internal positive control. This new detection system was validated and its specificity and detection limit were determined. Parallel analysis of 90 environmental samples to compare this method, a real-time PCR method and the standard culture isolation method, demonstrated that this seminested method is useful for the study of L. pneumophila.
