emm Typing of group A streptococcus clinical isolates: identification of dominant types for throat and skin isolatesDaisuke Tanaka
Department of Bacteriology, Toyama Institute of Health, Kosugi, Japan
Microbiol Immunol 46:419-23. 2002..To our knowledge, 3 T/emm is a novel combination. These results show that emm typing allows the characterization of group A streptococci from various sources...- Epidemiology and molecular analysis of group A streptococci from patients involved in food-borne disease outbreaks in Japan between 1996 and 2003Daisuke Tanaka
Department of Bacteriology, Toyama Institute of Health, Imizu, Toyama 939-0363, Japan

Department of Bacteriology, National Institute of Infectious Diseases, Toyama, Tokyo 162-8640, Japan
Jpn J Infect Dis 59:182-5. 2006..Antimicrobial susceptibility tests showed that all of the strains were susceptible to penicillin G, ampicillin, cefotaxime, clindamycin, and telithromycin. One strain showed intermediate resistance to erythromycin... - An outbreak of food-borne gastroenteritis caused by Clostridium perfringens carrying the cpe gene on a plasmidDaisuke Tanaka

Antimicrobial susceptibility survey of Streptococcus pyogenes isolated in Japan from patients with severe invasive group A streptococcal infectionsTadayoshi Ikebe
Department of Bacteriology, National Institute of Infectious Diseases, 1-23-1 Toyama, Shinjuku-ku, Tokyo 162-8640, Japan
Antimicrob Agents Chemother 49:788-90. 2005..4, and 0.5% of the isolates were resistant to erythromycin, clindamycin, telithromycin, and ciprofloxacin, respectively, and 10.4% had intermediate resistance to ciprofloxacin. All isolates were susceptible to ampicillin and cefotaxime...- [Molecular analysis of streptococcal pyrogenic exotoxin genes among group A Streptococcus isolates from Japanese patients with pharyngitis and skin infections]Daisuke Tanaka
Department of Bacteriology, Toyama Institute of Health
Kansenshogaku Zasshi 79:443-50. 2005..Among 15 skin isolates, 11 (73%) were lineage I and 4 (27%) were lineage II. The pairwise associations were observed between emm type and speA allele: emm1 and speA2, emm3 and speA3, emm6 and speA4, emm11 and speA2, emm18 and speA1... - Rapid categorization of pathogenic Escherichia coli by multiplex PCRKeiko Kimata
Department of Bacteriology, Toyama Institute of Health, Japan
Microbiol Immunol 49:485-92. 2005..Using our multiplex PCR, the 208 clinically isolated strains of diarrheagenic E. coli in our laboratory were successfully categorized and easily analyzed for the presence of virulence plasmids... - Dissemination of the phage-associated novel superantigen gene speL in recent invasive and noninvasive Streptococcus pyogenes M3/T3 isolates in JapanTadayoshi Ikebe
Department of Bacteriology, National Institute of Infectious Diseases, Tokyo, Japan
Infect Immun 70:3227-33. 2002..A horizontal transfer of the phage carrying speL may explain the observed change in M3/T3 S. pyogenes isolates in Japan... - Close correlation of streptococcal DNase B (sdaB) alleles with emm genotypes in Streptococcus pyogenesMasakado Matsumoto
Department of Microbiology, Aichi Prefectural Institute of Public Health, Nagoya, Japan
Microbiol Immunol 49:925-9. 2005..The distribution of each allele was generally emm genotype-specific. Only sdaB7 was found in both emm2 and emm4. The promoter region was highly conserved and DNase B protein was similarly expressed in all alleles... - Molecular mechanisms of high level tetracycline-resistance in group A streptococcal isolates, T serotypes 4 and 11Masakado Matsumoto
Department of Microbiology, Aichi Prefectural Institute of Public Health, Nagoya 462 8576, Japan
Int J Antimicrob Agents 25:142-7. 2005..These results strongly suggested that the T4 and T11 GAS isolates acquired tetracycline-resistance via different molecular mechanisms... - Genetic features of clinical isolates of Streptococcus dysgalactiae subsp. equisimilis possessing Lancefield's group A antigenDaisuke Tanaka
Graduate School of Science and Engineering, University of Toyama, 3190 Gofuku, Toyama 930 8555, Japan
J Clin Microbiol 46:1526-9. 2008..The results indicate that a conserved clone has persisted and spread within Japan, and two different emm types were observed within members of this clone... - Trehalose transporter 1, a facilitated and high-capacity trehalose transporter, allows exogenous trehalose uptake into cellsTakahiro Kikawada
National Institute of Agrobiological Sciences, Ohwashi 1 2, Tsukuba, Ibaraki 305 8634, Japan
Proc Natl Acad Sci U S A 104:11585-90. 2007..These characteristic features imply that TRET1 in combination with trehalose has high potential for basic and practical applications in vivo...
