V-chloramphenicol acetyl transferase |
Qualitative real-time PCR (TaqMan) method for detection of the chloramphenicol marker potentially harboured by GMM in food enzyme preparations (Turgeon et al. 2008).
In term of food and feed safety, to evaluate the level of risks of likely AMR (antimicrobial resistance) gene acquisition by pathogens and gut microbiota, it is essential to determine if the full-length AMR genes are present. In order to assess the presence of the full-length cat gene a successive nested-PCR method can be performed to amplify a large fragment of the cat gene be performed (Fraiture et al. 2020) (see Related Methods QL-ELE-cat-F1/R1 and QL-ELE-cat-F2/R2). |

V-chloramphenicol acetyl transferase |
Qualitative conventional PCR for detection of the full-length Chloramphenicol marker gene that is frequently harboured by GMM in food enzyme preparations (Fraiture et al. 2020).
In detail, the potential presence of the chloramphenicol marker is first screened using a real-time PCR method (Turgeon, Laflamme, Ho, & Duchaine, 2008)(see Related Methods QL-ELE-cat-F/R). In case a positive real-time PCR signal is obtained, the presence of the full-length chloramphenicol marker is then evaluated by a nested-PCR consisting of this method and the related method QL-ELE-cat-F2/R2. |
