Background: Pairwise single nucleotide polymorphisms (SNPs) are a cornerstone for genomic approaches to multidrug-resistant organisms (MDROs) transmission inference in hospitals. However, the impact of key analysis parameters on these inferences has not been systematically analysed. Methods: We conducted a multi-hospital 15-month prospective study, sequencing 1537 MDRO genomes for comparison; methicillin-resistant Staphylococcus aureus , vancomycin-resistant Enterococcus faecium , and extended-spectrum beta-lactamase-producing Escherichia coli and Klebsiella pneumoniae . We systematically assessed the impact of sample and reference genome diversity, masking of prophage and regions of rec..
