Abstract
A pathogen was examined in 58 patients with chronic suppurative otitis media who visited our clinic during a 1 year and 5 month period from February 1, 2006. We also evaluated the sensitivity of the bacterial species to 7 antimicrobials. Of the 68 bacterial strains identified in 52 patients, 36 (52.9%) and 4 (5.9%) were Staphylococcus aureus and Pseudomonas aeruginosa, respectively. In addition, no bacterial strain was detectedin the samples obtained from the remaining 6 patients. Antimicrobial testing revealed that 29 (80.6%) of these 36 S. aureus strains were resistant to ampicillin. Those 29 strains were highly sensitive to minocycline (96.6%), but showed lower sensitivity to levofloxacin (62.1%), cefcapen (55.2%), cefditoren (55.2%), clarithromycin (48.3%) and azithromycin (48.3%). Three of the 4 P. aeruginosa strains were sensitive to levofloxacin, although these 4 strains were resistant to all of the other 6 antimicrobials.
