Here we describe two plasmids carrying mcr-4.3 in two Acinetobacter baumannii strains isolated from imported food and a clinical sample. The comparative analysis of these plasmids, with two other plasmids reported in NCBI database, highlighted the common origin of the plasmidic structure carrying mcr-4.3.
This is the first case of mcr-4.3 gene in A. baumannii strain isolated from a clinical case in Europe. We hypothesize that food import is initiating the spread in Czech Republic.
