CRISPR/CAS9 BASED DNA-COMBING ASSAY FOR DETECTING ANTIMICROBIAL RESISTANCE GENES ON PLASMIDS

Summary, in English

We present a method based on CRISPR/Cas9 excision and DNA combing to detect anti-microbial resistance (AMR) genes on bacterial plasmids. The assay is inexpensive, simple, fast, and also provides information on the number and size of plasmids in a sample. We demonstrate detection of the gene encoding for the New Delhi metallobeta-lactamase 1 (blaNDM-1) enzyme, known to make bacteria resistant to a broad range of beta-lactam antibiotics.
