V. cholerae Var enhances As^V resistance in enteropathogenic bacteria. (A) Hierarchical heat map clustering of enteropathogenic bacteria with respect to V. cholerae based on the percentage identity of var genes. (B) Growth curves (OD₆₀₀) of the As^V-sensitive enteropathogenic bacteria clustered in panel A, carrying an inducible empty plasmid (empty circle) or the same plasmid expressing the V. cholerae var operon (blue filled circle). Cultures were grown in LB medium in the presence of 10 mM As^V. Data from panel B are the mean of three biological replicates ± SEM.
