Fig. 5From: Ursolic acid inhibits colistin efflux and curtails colistin resistant EnterobacteriaceaeUrsolic acid with colistin causes effective membrane depolarization in E. coli U3790 and K. pneumoniae BC936. Mid log cells of U3790 and BC936 were treated with colistin (Col), ursolic acid (UR) and colistin + ursolic acid (Col + UR) in the presence of DiSc3. The fluorescent intensity was measured at Ex 605 nm and Em 665 nmBack to article page
