The study on drug resistance of MDR-AB strain. Polymyxins B (A), MER (B), Cefalexin (C), Cefotaxime (D), and different concentrations of GA (E) were incubated with MDR-AB for 24 h, respectively, and OD values were measured by microplate meter. The expression of Bfm (F), VIM (G), blaOXA-51 (H), Aded (I), and Adej (J) were detected by RT-PCR after GA and MDR-AB were co-cultured for 24 h.^*P < 0.05 vs. control group; ^**P < 0.01 vs. control group
