Molecular Analysis of Toxigenic Clostridium difficile Isolates from Hospital Environment by PCR Ribotyping Method
Background and Aims: Clostridium difficile is an identified cause of antibiotic-associated diarrhea, antibiotic-associated colitis, pseudomembranous colitis and nosocomial diarrhea. The objective of this survey was to determine molecular analysis of toxigenic Clostridium difficile isolates from hospital environment in Tehran tertiary medical centers. Materials and Methods: In this descriptiv...
متن کاملDetection of Virulence Genes of Clostridium difficile in Children with Cancer by Multiplex PCR
Introduction: Toxigenic Clostridium difficile is the major cause of antibiotic-associated diarrhea, colitis, and pseudomembranous colitis. The pathogenicity of C. difficile is related to toxins A&B. Children with cancer are at risk of developing C. difficile infection (CDI) due to increased exposure to antibiotics, immunosuppression, and longer hospital stays. Recently, due to higher sensitivity...
متن کاملToxin profiles and antimicrobial resistance patterns among toxigenic clinical isolates of Clostridioides (Clostridium) difficile
Objective(s): Clostridioides (Clostridium) difficile infection as a healthcare-associated infection can cause life-threatening infectious diarrhea in hospitalized patients. The aim of this study was to investigate the toxin profiles and antimicrobial resistance patterns of C. difficile isolates obtained from hospitalized patients in Shiraz, Iran.Mater...
متن کاملGenetic characterization of toxin A-negative, toxin B-positive Clostridium difficile isolates by PCR.
Toxin-specific enzyme immunoassays, cytotoxicity assays, and PCR were used to analyze 48 toxin A-negative, toxin B-positive Clostridium difficile isolates from various geographical sites around the world. All the isolates were negative by the TOX-A TEST and positive by the TOX A/B TEST. A deletion of approximately 1.7 kb was found at the 3' end of the toxA gene for all the isolates, similar to ...
متن کاملCharacterization of Clostridium difficile isolates using capillary gel electrophoresis-based PCR ribotyping
We have developed a Clostridium difficile PCR ribotyping method based on capillary gel electrophoresis and have compared it with conventional PCR ribotyping. A total of 146 C. difficile isolates were studied: five isolates were reference strains (PCR ribotypes 001, 014, 017, 027 and 053); 141 were clinical isolates comprising 39 Austrian PCR ribotypes collected in the period 2006-2007 at 25 Aus...
