We employed Oxford Nanopore Technology (ONT) long read sequencing, together with Illumina short read sequencing, and performed a detailed in silico characterization of Stx2a encoding phages from eight STEC O145:H25 isolated from patients with hemorrhagic diarrhea and HUS in Norway between 2007 and 2018. The gene discussed is STX2; the disease is hemolytic-uremic syndrome.
