A total of 19,753 strains of gram-negative rods collected during two 6-month periods (October 2000 to March 2001 and November 2001 to April 2002) from 13 clinical laboratories in the Kinki region of Japan were investigated for the production of metallo-beta-lactamases (MBLs). MBLs were detected in 96 (0.5%) of the 19,753 isolates by the broth microdilution(More)
The aim of this study was to research the distribution in the Kinki region of Japan of Enterobacteriaceae and Pseudomonas aeruginosa that produce extended-spectrum beta-lactamase (ESBL) and metallo beta-lactamase (MBL). One thousand isolates, 200 of each of four enterobacterial species (i.e. Escherichia coli, Klebsiella pneumoniae, Enterobacter cloacae and(More)
Pacemaker infection is one of the severe complication of pacemaker implantation. We report a case of pacemaker infection caused by Staphylococcus schleiferi which is a coagulase-negative staphylococcus, and its relation with human infection is not well characterized. In 1994, a 80-year-old male presented with a pacemaker pocket infection, cutaneous(More)
Extended-spectrum beta-lactamase (ESBL)-producing bacteria are known to be resistant to penicillins, cephalosporins, and monobactams because of their substrate specificity, and these bacteria are sensitive only to a narrow range of antimicrobial agents. The present study was undertaken to evaluate the efficacy of carbapenems and the new quinolones against(More)

We studied the susceptibility to penicillin G (PCG) and other antimicrobiotics in 235 clinical isolates of Streptococcus pneumoniae. Samples were collected between April 1 and June 30, 2000 from nine medical institutions of the Kinki Region of Japan. We classified the minimum inhibitory concentration (MIC) of PCG according to the National Committee for(More)
We studied antimicrobial susceptibility and beta-lactamase types among clinical isolates in the Kinki area of Japan. Eight hundreds isolates of eight organisms were collected by seven medical institutions during January and February 2000. The rates of beta-lactamase producing by using the chromogenic nitrocephin test were 68.0% against Staphylococcus aureus(More)
