Time-Kill Study of the Activity of Telithromycin against Macrolide-Resistant Streptococcus pneumoniae Isolates with 23S rRNA Mutations and Changes in Ribosomal Proteins L4 and L22
Description:

<jats:p>
By use of a time-kill methodology, the antipneumococcal activity of telithromycin was determined against macrolide-resistant
<jats:italic>S. pneumoniae</jats:italic>
isolates having mutations in the 23S rRNA gene and changes in the ribosomal proteins L4 and L22. Telithromycin had MICs ranging between 0.03 and 0.25 μg/ml and was bactericidal against four of seven strains after 24 h at two times the MIC.
