title: Bacteremic pneumonia due to multidrug-resistant pneumococci in 3 patients treated unsuccessfully with azithromycin and successfully with levofloxacin.
abstract: Three patients with bacteremic pneumonia caused by multidrug-resistant Streptococcus pneumoniae were treated unsuccessfully with azithromycin. One S. pneumoniae isolate carried a mef determinant for an efflux pump; a second isolate had an erm determinant. All 3 patients were successfully treated with levofloxacin, an antipneumococcal fluoroquinolone.
