Evaluation of Rapid Assay (Tox A/B Quik Chek) for the Detection of Clostridium difficile Toxins A and B

Original article PDF Sue Jung Kim1, Heejung Kim1, Myung Sook Kim1, Eunmi Koh1, Chang-Ki Kim2, Seok Hoon Jeong1, Yunsop Chong1, Kyungwon Lee1 1Department of Laboratory Medicine and Research Institute of Bacterial Resistance, Yonsei University College of Medicine; 2Korean Institute of Tuberculosis, Seoul, Korea Corresponding to Kyungwon Lee, E-mail: leekcp@yuhs.ac Ann Clin Microbiol 2008;11(2):112-116.Copyright © Korean Society of Clinical Microbiology. Abstract Background: Toxin immunoassay is widely used for rapid diagnosis of Clostridium difficile-associated diarrhea. The aim of this study was to evaluate the performance of Tox A/B Quik Chek test (TECHLAB, Blacksburg, VA, USA) compared to toxigenic culture. Methods: From September 2006 to August 2007, 959 stools were examined by Tox A/B Quik Chek test and toxigenic culture (C. difficile culture plus tcdB PCR using colonies obtained from culture). Results: Compared to the results of toxigenic culture, the sensitivity and specificity of Tox A/B Quik Chek test were 47.5% and 97.5%, respectively. Conclusion: The sensitivity

Evaluation of a ChromID C. difficile Agar for the Isolation of Clostridium difficile

Original article PDF Ji-Sook Yim, Seock-Mi Hwang, Myungsook Kim, Hee-Joung Lim, Saeam Shin, Hae-Sun Chung, Heejung Kim, Kyungwon Lee Department of Laboratory Medicine and Research Institute of Bacterial Resistance, Yonsei University College of Medicine, Seoul, Korea Corresponding to Heejung Kim, E-mail: hjkim12@yuhs.ac Ann Clin Microbiol 2012;15(3):88-91. https://doi.org/10.5145/KJCM.2012.15.3.88Copyright © Korean Society of Clinical Microbiology. Abstract Background: Clostridium difficile is the main etiologic agent of antibiotic-associated diarrhea and the most common cause of hospital-acquired diarrhea. Recently, the incidence of C. difficile infections (CDI) has increased and new highly virulent C. difficile strains have emerged. Therefore, accurate and rapid diagnosis is needed. We compared the results of using chromID C. difficile (chromID CD, bioMeriéux, France) with the conventional C. difficile Selective Agar (CDSA; BD, USA) for the isolation of C. difficile. Methods: A total of 738 stool specimens of suspected CDI patients at the Severance Hospital from July to August 2011 were inoculated

Increase of Clostridium difficile in Community; Another Worrisome Burden for Public Health

Original article PDF Young Ah Kim1, John Hoon Rim2, Min Hyuk Choi2, Heejung Kim2, Kyungwon Lee2 1Department of Laboratory Medicine, National Health Insurance Service Ilsan Hospital, Goyang, 2Department of Laboratory Medicine and Research Institute of Bacterial Resistance, Yonsei University College of Medicine, Seoul, Korea Corresponding to Heejung Kim, E-mail: hjkim12@yuhs.ac Ann Clin Microbiol 2016;19(1):7-12. https://doi.org/10.5145/ACM.2016.19.1.7Copyright © Korean Society of Clinical Microbiology. Abstract Background: Increasing rates of Clostridium difficile infection (CDI) have been reported mainly in Europe and North America; however, only limited reports have originated in Korea. The current epidemiology of CDI in the community could help to understand the outpatient healthcare environment and to extend infection control measures to outpatient settings. Methods: C. difficile isolates in NHIS Ilsan Hospital from 2012 to 2014 were included in this study. Clinical characteristics, acquisition types, and previous antimicrobial therapy were obtained via Electronic Medical Records. C. difficile culture was performed only in
