High prevalence of the ermB gene among erythromycin-resistant streptococcus pneumoniae isolates in Germany during the winter of 2000-2001 and in vitro activity of telithromycin.

Abstract excerpt

Of 595 isolates of Streptococcus pneumoniae from outpatients with respiratory tract infections, collected from 17 microbiology laboratories, 14.1% were resistant to erythromycin. Eighty-three erythromycin-resistant isolates were genetically analyzed, 83.1% of which harbored the ermB gene. Only four isolates (4.8%) harbored the mefA gene. Telithromycin exhibited potent activity against all isolates.
