| molecular and epidemiological study of the first outbreak of vanb type vancomycin-resistant enterococcus faecalis in japan. | in july, 1999, an outbreak of vancomycin-resistant enterococcus faecalis (vref) with the vanb genotype occurred for the first time in japan at hokushin general hospital, nakano city, nagano prefecture. four vref strains were isolated from the clinical specimens of four inpatients, and 16 vref strains were isolated by the screening of asymptomatic carriers and by surveillance of the hospital environment. all of the isolates possessed vanb genes. in a pulsed-field gel electrophoresis analysis, 19 ... | 2001 | 11326124 |
| [antimicrobial susceptibility and beta-lactamase productivity of recent clinical isolates during the period between december 1999 and february 2000]. | antimicrobial susceptibility testings of 24 antimicrobial agents against 605 clinical strains belonging to 10 species were carried out according to the micro-broth dilution method of nccls m7-a4. the productivity of beta-lactamase was also determined against them isolated at 8 medical facilities in nagano prefecture, japan during the period between december 1999 and february 2000. when applied the nitrocefin method, beta-lactamase productivity was demonstrated to be positive for 89.2% of 74 s. a ... | 2002 | 12599534 |
