FIGURE 1. Genetic context of the mcr-9.1 gene in the colistin-resistant Enterobacter kobei strain E11R. IS903Band IS26 elements were found upstream and downstream ofmcr-9.1 in a similar way that in MCR-9-producingSalmonella Saintpaul [CVM N16S133 (CP049986.1), NY-N14748 (CP048926.1), CVM N40391 (CP049983.1) and CVM N52030 (CP049981.1)],S. Heidelberg [CVM N16S321 (CP049313.1), CVM N58631 (CP049307.1) and CVMN53023 (CP049310.1)], and S. Albany [CVM N18S2238 (CP049312)] strains isolated from ground turkey; S.Johannesburg [CVM N58011 (CP049309)] strain isolated from chicken breast; and E. coli [CVM N18EC0432 (CP048293.1)] strain isolated from chicken wings, in the United States of America (Tyson et al., 2020).
FIGURE 2. Global distribution of MCR-9-positive Enterobacterales. The occurrence of MCR-9- producing Enterobacterales (i.e., Citrobacter freundii , Enterobacter cloacae ,Enterobacter hormaechei , Enterobacter kobei ,Escherichia coli , Klebsiella oxytoca , Klebsiella pneumoniae , Klebsiella quasipneumoniae , Klebsiella variicola , Providencia alcalifaciens , and Salmonella enterica ) has been reported in Argentina, Belgium, Brazil, China, Denmark, Egypt, France, Germany, Japan, Montenegro, Poland, Qatar, Romania, Serbia, Slovenia, South Africa, Spain, Sweden, and the United States of America, from human and non-human sources Data search was updated in the PubMed database on July 20, 2020.
