Differential Afa/Dr fimbriae expression in the multidrug resistant Escherichia coli ST131 clone

In this project, we described the diversity and prevalence of afa/dr fimbria genes in ST131, revealing the dominance of a new afaE-IX allelic variant. We additionally showed how different IS elements can alter the regulation of afa transcription and provide evidence for a more widespread impact of IS1 on ST131 genome evolution.The genomes in this BioProject are 4 ST131 representative strains with different IS elements located in the promoter region of afa operon. These genomes are assembled using Nanopore long reads and polished with Illumina short reads.
