Effect of sub-minimum inhibitory concentration (MICs) of ciprofloxacin on biofilm formation in Escherichia coli ATCC 25922. (A) Biofilms of E. coli ATCC 25922 treated with sub-MIC of ciprofloxacin appears dispersed and sparse. (B) Biofilms of E. coli ATCC 25922 cultured without ciprofloxacin appears dense.
