Abstract Rothia spp. are aerobic, gram-positive cocci belonging to the family Micrococcaceae, and are a part of the normal microbial flora of the human oropharynx and upper respiratory tract. We present the first case of the prosthetic valve endocarditis with cerebral hemorrhage caused by Rothia mucilaginosa in South Korea. A 65-year-old man with a prosthetic aortic valve visited the outpatient clinic with a complaint of fever. R. mucilaginosa was identified in one among four sets of blood culture bottles obtained

Abstract Background: We evaluated the performance of ASTA MicroIDSys (ASTA, Korea) and Bruker Biotyper (Bruker Daltonics, Germany) systems in the identification of bacterial isolates from clinical microbiology laboratory specimens during the study period. In addition, species for which the identification accuracy using MALDI-TOF MS systems was previously reported to be poor were also identified by comparing the MS results with those obtained using molecular identification. Methods: A total of

Abstract Background: β-lactam antibiotics are one of the most frequently used antimicrobial agents. However, with the increase of β-lactamase-producing bacteria, penicillins and 1st generation cephalosporins have become less useful. Cefatrizine and clavulanic acid combination (CTCA) was developed to restore the activity. The aim of this study was to determine the activities of CTCA against major recent clinical isolates. Methods: Aerobic and anaerobic bacteria tested were isolated from clinical specimens in Severance Hospital during 1996 to 1999. Antimicrobial

Abstract Background ： Increased isolation of extended-spectrum β-lactamase ( ESBL)-producing Enterobacteriaceae resistant to third generation cephalosporins and aztreonam has been noted recently. This study was to determine the prevalence of resistance to these drugs and ESBL in Enterobacteriaceae and to evaluate the methods for detection. Methods：During the period of October, 1997 and March, 1998, a total of 731 clinical isolates of Enterobacteriaceae were collected from patients of the Kosin Medical Center, Pusan, Korea. Antimicrobial susceptibility test by disk diffusion method and double disk synergy
