Molecular and Phenotypic Characteristics of Escherichia coli Isolates from Farmed Minks in Zhucheng, China

Figure 4

Diversity profiles of the phylogenetic tree, drug resistance genes, antimicrobial resistance, and Class 1 integron structure. Note. Dendrogram of seven allele sequence types from 50 E. coli isolates from minks. ST11 is included as the reference. The three shaded parts in the figure represent three clonal complexes, CC10, CC46, and CC176 from top to bottom. The unit information is the number of isolated strains followed by the ST type and Class 1 integron structure IntA, dfrA27+aadA2+qnrA; IntB, dfrA17+aadA5; IntC, dfrA12+aadA2; or IntD, dfrA1+aadA1. (1) The 14 detected resistance genes were shown in the left matrix: a red square indicates that the strain carries the resistance gene, and a light blue square indicates that the resistance gene is not detected. (2) Antibiotics used in this experiment were shown in the right matrix: a blue square indicates that the strain is resistant to the antibiotic, and a light blue square indicates that the strain is not resistant.
