임상미생물 검사 결과에 기반한 자동화된 유행 알림 시스템의 활용
어영 대한의료관련감염관리학회 2022 의료관련감염관리 Vol.27 No.2
Clinical microbiological test results are fundamental in preventing of healthcare-related infections, but the test methods and interpretative criteria for antimicrobial susceptibility tests vary, depending on the period. Therefore, to effectively utilize the automated epidemic notification system based on the results of the clinical microbial test, it is necessary to build a test code system that can be expanded and allows the management of history to reflect changes in the clinical microbial tests. The level and scope of the establishment of the infection epidemic monitoring system depends on the characteristics of the medical institution, policy direction of the hospital decision-making management, details of the computer hardware, peripheral devices, and the software and personnel supporting it.

Although Leuconostoc species have rarely been isolated from clinical specimens, this organism may cause invasive infections such as bacteremia and meningitis in immunocompromised patients. We report a case of Leuconostoc garlicum bacteremia in an 84-year-old male with hemovac catheter placement, vancomycin therapy, and inflammatory enterocolitis as underlying risk factors.

Background : The frequency of nosocomial bloodstream infections by Candida species has risen dramatically in the past two decades, and a noticeable shift in the species of Candida causing bloodstream infection toward non-albicans species has occurred. Also, the isolation frequency of Candida species are infuenced by patient type, nation and region, study period, and investigators. The aim of this study is to investigate the isolation rates and antifungal susceptibility of Candida species isolated from blood cultures at Wonju Christian Hospital during the recent four years (1997-2000). Methods : For one-hundred twenty-seven isolates of Candida species from blood cultures, we analyzed the isolation frequency by year, age/sex, and department. Identification of yeasts was done by germ tube test and ATB ID 32 C kit. Antifungal susceptibilities to flucytosine, amphotericin B, nystatin, miconazole, econazole, and ketoconazole were determined by ATB FUNGUS. Results : The isolation rates of Candida species in decreasing order were C. albicans (44.9%), C. parapsilosis (21.3%), C. gkabrata (14.2%), and C. tropicalis (9.5%). The isolation rates of Candidα species by year were as follows; C. akbucabs decreased from 61.5% in 1997 to 33.3% in 2000; C. tropicalis decreased from 23.1% in 1997 to 5.0% in 2000; C. parapsilosis increased from 0% in 1997 to 30.8% in 2000; and C. glabrata increased from 7.7% in 1997 to 18.0% in 2000. Of 127 Candida species, all but one isolates were susceptible to amphotericin B. Conclusion : This data showed that the candidemin by C. albicans and C. tropicalis are decreasing trend, and candidemia by C. parapsilosis and C. glabrata are increasing trend in recent four years.

최근 4년간(1997~2000) 원주지역 3차 병원에서 분리된 β-용혈성 연쇄구균의 혈청군별 분리 분포
어영,장인호,윤갑준,김효열 대한감염학회 2001 감염 Vol.33 No.3
Background : Beta-hemolytic streptococci (BHS) are frequently isolated pathogens in the clinical microbiology laboratory, and the isolation frequency of each serogroup of BHS are influenced by patient type, nation and region, study period, and investigators. The aim of this study is to investigate the isolation rates and distribution of BHS by serogroup at Wonju area during the recent periods. Methods : Isolation rates of BHS isolated from 1997 to 2000 at Wonju Christian Hospital were investigated. The distribution of each serogroup of BHS according to the types of clinical specimens was also studied. Serogroups A, B, C, F, and G were determined by latex agglutination test (Murex Streptex kit). Results : Of 627 BHS isolated during the study periods, 16.3% were group A, 49.3% were group B, 5.1% were group C, 4.3% were group F, 21.0% were group G, and 4.0% were nongroupable. Isolation rates of BHS by specimen type were as follows : wound/pus was 44.4%; cervix, urine, and respiratory specimen ranged from 10% to 20%; blood was 4.0%; body fluid was 2.9%; and cerebrospinal fluid was 0.5%. The prevalent isolation sites by serogroup were : group A, wound/pus (78.4%); group B, cervix (32.7%), urine (28.5%), and wound/pus (26.2%); group C and G, wound/pus and respiratory specimen; and group F, wound/pus and urine. From blood, group B streptococci (44.0%) were the most frequent isolate. Conclusions: Half of BHS isolated from clinical specimens were group B streptococci in this study, which reflects the increasing trend of group B streptococcal infections during the recent years at Wonju area.
