Table 4  Antimicrobial resistance gene on plasmids predicted by ResFinder and PlasmidFinder after de novo assembly of clinical E. coli strains with ONT reads using Flye, Canu, Wtdbg2, and NECAT assemblers with and without read correcting with Medaka, NextPolish, and Racon. F = Flye, C = Canu, W = Wtdbg2, NE = NECAT, M = Medaka, NP = NextPolish, R = Racon

From: The impact of applying various de novo assembly and correction tools on the identification of genome characterization, drug resistance, and virulence factors of clinical isolates using ONT sequencing
