  • Fast identification of Escherichia coli in urinary tract ...

    2020-2-1 · Our novel method was able to detect E. coli of phylogenetic groups A, B1, B2, D, F, and clade V across diverse sample types, including a vast majority of uropathogenic E. coli. Moreover, the novel (Nextgen) PCR thermal cycler allowed ultrafast PCR amplification, in 16 min (total E. coli identification in 52 min, including DNA extraction, PCR, electrophoresis, staining, destaining and visualization under UV).
