Specifically they engineered non-pathogenic A. baylyi to detect donor DNA released from CRC cells, organoids, and tumours. Integration of tumour DNA into the bacterial genome conferred resistance to the antibiotic kanamycin; antibiotic kanamycin works by killing bacteria or preventing their growth. However, this medicine will not work for colds, flu, or other virus infections. Kanamycin is used to treat tuberculosis of the lungs and other organs upon resistance to other antituberculosis drugs. As such, kanamycin selection could be used as an easily measurable output for detecting colorectal tumours. Capitalising on the inherent ability of A. baylyi to take up foreign DNA through horizontal gene transfer (HGT), a phenomenon known as natural competence, this represented the...
