*abbreviations as defined by Achtman et al. [7] and Morelli et al. [6]: PE – pestoides (microtus), ANT – Antiqua, IN – Intermedium, ORI – Orientalis, and MED – Medievalis; Intermedium in Morelli et al. [6] has not the same meaning as intermedium defined by Li et al. [5] which refers to Rhamnose positive Y. pestis pestis isolates.
