A new bacterial identification method, called ON-rep-seq, examines selective, strain-specific fragments of the bacterial genome, allowing the generation of results that earlier required DNA sequencing of the entire bacterial genome or tedious approaches like pulsed field gel electrophoresis, which previously has been the gold standard for strain-level typing of microorganisms. Hence, the method has the potential to change the approach utilized for investigating food-based disease outbreaks by making analysis much less time- and cost consuming.
