Increased macrolide resistance of Mycoplasma pneumoniae in France directly detected in clinical specimens by real-time PCR and melting curve analysis

摘要

Objectives Mycoplasma pneumoniae is a common aetiological agent of community-acquired respiratory tract infections for which macrolides are the treatment of choice. In France, only two macrolide-resistant isolates were reported in 1999. In contrast, several recent data reported that macrolide-resistant M. pneumoniae isolates have been spreading since 2000 in Japan. Mutations A2058G (Escherichia coli numbering), A2058C, A2059G, A2062G, C2611A and C2611G in domain V of the 23S rRNA gene were associated in vivo or in vitro with this resistance. The aim of this study was to determine whether macrolide resistance of M. pneumoniae is emerging in France.
