Effects of drug combination on preventing biofilm formation. (A) A. baumannii QS17-1084 was treated with MUT056399 and brilacidin at the ratio 1:2. (B) A. baumannii 5075 was incubated with MUT056399 and eravacycline at ratio 1:2. The drug concentrations were similar to those used in the time-kill assay. A. baumannii ATCC19606 and E. coli ATCC25922 were included as positive and negative biofilm producing strains, respectively. P < 0.05 was analyzed by using Student’s t-test. The representative images are biofilms stained by crystal violet.
