Median (minimum–maximum) allele differences and pulsed-field gel electrophoresis (PFGE ) patterns for Listeria monocytogenes isolates from clinical and food samples associated with a 2014 cluster of listeriosis cases and a 2013 listeriosis case, Rhode Island, USA. Allele differences were determined by whole-genome multilocus sequence typing (wgMLST).
