YUKO ASANO Department of Clinical Laboratory Medicine, Ogaki Municipal Hospital HIROYUKI SUEMATSU Clinical Laboratories, Chuno Kosei Hospital YUUKI KAWAHARA Takayama Red Cross Hospital SHIGENORI MATSUBARA Matsubara Otorhinolaryngology Clinic TORU ARAI Tohno Kosei Hospital KUNITOMO WATANABE Division of Anaerobe Research, Life Science Research Center, Gifu University KAZUKIYO YAMAOKA Gifu University of Medical Science HARUKI SAWAMURA Gifu University School of Medicine MAYUMI TERAJI Hida Medical Laboratory YOKO MATSUKAWA Clinical Laboratories, Gifu Prefectual Tajimi Hospital TAKANORI MIYABE Clinical Laboratories, Tokai Central Clinical Laboratories, Tokai Central Hospital HIROSHIGE MIKAMO Department of Infection Control and Prevention, Aichi Medical University We investigated the susceptibility to antibacterials, genotype of penicillin-binding protein PBP genes and macrolide resistant genes, and the serotypes against 377 strains of Streptococcus pneumoniae isolated from medical facilities in Gifu and Aichi prefectures between June 2008 and April 2009. These results were compared with those against 160 strains of S. pneumoniae isolated in 2004. Referring to CLSI M100-S17, the overall incidence of penicillin-susceptible PSSP, penicillin-intermediate PISP and penicillin-resistant PRSP S. pneumoniae was 143 38%, 185 49% and 49 13% strains, respectively. PISP and PRSP were isolated higher in the material of nasal cavity and throat, and PRSP was isolated higher in the area of Chuno district. The number of gpssp with 3 normal PBP genes, gpisp with 1 or 2 normal PBP genes and gprsp with 3 abnormal genes was 23 6.1%, 173 46% and 181 48% strains, respectively. The isolates with no macrolide-resistant gene, only mefa, only ermb, and both mefa and ermb were 28 7.4%, 138 37%, 166 44% and 45 12%. The prevalent pneumococcal serotypes were type 19 92 strains; 24%, following by type 23 60 strains; 16% and type 6 56 strains; 15%. The 80% of pneumococcal serotypes of PRSP were serotype 19 and 6. The MIC 90 of each antibacterial was as follows; 0.1 g/ml for imipenem, panipenem and garenoxacin, 0.2 g/ml for moxi oxacin, 0.39 g/ml for meropenem and tosu oxacin, 0.78 g/ ml for amoxicillin, clavulanic acid/ amoxicillin, cefditoren and cefcapene, 1.56 g/ml for benzylpenicillin, piperacillin, cefteram and levo oxacin, 3.13 g/ml for cefotiam, omoxef and pazu oxacin, 6.25 g/ml for cefdinir, 12.5 g/ml for nor oxacin and minocycline, >100 g/ml for clarithromycin, and these MIC 90 s were about the same as those in 2004.
