Nanofluidic optical DNA mapping for rapid identification of antibiotics resistant plasmids

Paper i proceeding, 2018

Bacterial resistance to antibiotics has become a major threat to health worldwide. In 2014, the World Health Organization (WHO) classified antibiotic resistance as one of the major threats to human health.1 As the resistance genes are frequently transmitted via mobile genetic elements, such as plasmids, a method to rapidly detect and identify plasmids is needed. This paper reports an improved nanofluidic optical mapping strategy to identify plasmids and locate the antibiotic resistance genes via the Cas9/CRISPR technique. We used the assay to analyze clinical samples from a potential nosocomial outbreak in an Ethiopian hospital, tracing the transmission routes among wards.
