First report of macrolide-resistant strains and description of a novel nucleotide sequence variation in the P1 adhesin gene in Mycoplasma pneumoniae clinical strains isolated in France over 12 years.

ABSTRACT: Mycoplasma pneumoniae isolates are divided in two types based on the sequence variations in the P1 adhesin gene. The type of P1 adhesin gene of 155 clinical isolates of M. pneumoniae collected in France between 1994 and 2006 was determined by a PCR-restriction fragment length polymorphism method. Until 1995, all strains belonged to type 1. In 1996 and 1997, type 1 was still predominant, but type 2 increased. Finally, since 1998, both types were present in about the same proportion. In our study, a novel sequence of the P1 adhesin gene was described in one strain. This strain could not be classified into type 1 or 2 because of variability in both P1 gene repeat elements, RepMP4 and RepMP2/3. This new sequence was certainly issued from recombination with repetitive sequences localized outsid
