WebJun 1, 2024 · Clostridioides difficile causes nosocomial outbreaks which can lead to severe and even life-threatening colitis. Rapid molecular diagnostic tests allow the identification of toxin-producing, potentially hypervirulent strains, which is critical for patient management and infection control. PCR-ribotyping has been used for decades as the reference … WebJul 21, 2024 · Like PFGE, ribotyping also produces a pattern of DNA fragments, but the technique is different. As we saw with PFGE, ribotyping starts with DNA extracted from isolates. A restriction enzyme then cuts the DNA at specific locations, generating fragments of DNA of varying lengths.

WebJun 1, 1999 · PCR-ribotyping, a typing method based on polymorphism in the 16S-23S intergenic spacer region, has been recently used to investigate outbreaks due to Clostridium difficile. However, this method generates bands of high and close molecular masses which are difficult to separate on agarose gel electrophoresis. WebTyping by PCR ribotyping and pulsed-field gel electrophoresis demonstrated clusters of carriers colonised by a single type in each of three groups, indicating that cross-transmission of C. difficile can occur in community settings.
