Characteristics of 34 M. pneumoniae-positive respiratory tract specimens collected at the University Hospital of Bordeaux, France over three years (October 2007–September 2010) and of the corresponding M. pneumoniae isolates grown from them.

aBAL, bronchoalveolar lavage; pleural liq., pleural liquid; NPA, nasopharyngeal aspirate; bronch. asp., bronchial aspirate.bCycle threshold from the in-house real-time PCR targeting the M. pneumoniae adhesin P1 used for primary detection of the pathogen [19].cwt, wild type; no amp, no amplification with the real-time PCR used for the detection of 23S rRNA mutations associated with macrolide resistance according to Peuchant etal.[21]. Substitution A2059G (E. coli numbering) corresponds to substitution A2064G using M. pneumoniae numbering.dNo M. pneumoniae isolate grown from the specimen.eConcurrent specimens from the same patient collected the same day.fSequential specimens from the same patient.gnd, not determined.hInconsistencies concerning the marker Mpn1 leading to distinct MLVA types are underlined.
