No inhibition of MCR-1 production by Pingwei Pill treatment. Bacteria carrying mcr-1 were cocultured with the indicated concentrations of Pingwei Pill for 4 h and 6 h. The production of MCR-1 in the cultured supernatant was determined using Western blot analysis. Blots and densitometry ratio analyses of K. pneumoniae ZJ02 (A), E. coli ZJ478 (B), E. coli DH5α (pUC19-mcr-1 (C) and Salmonella sp. strain HYM2 (D). ICDH (isocitrate dehydrogenase) as the reference. Data are shown with representative blots of each strain from one trial (n = 3)
