Effect of combination gentamicin, imipenem, and, fucoidan on dual-species biofilms of Staphylococcus aureus and Acinetobacter baumannii. (A) single-species biofilm S. aureus (Untreated), (B) single-species biofilm A. baumannii (Untreated), (C) dual-species biofilm of S. aureus and A. baumannii (Untreated), (D) dual-species biofilm treated with 32 μg/mL gentamicin and 64 μg/mL imipenem, (E) dual-species biofilm treated with 32 μg/mL gentamicin and 31.2 μg/mL fucoidan, (F) dual-species biofilm treated with 31.2 μg/mL fucoidan and 64 μg/mL imipenem. LBB, large biofilm biomass; SBB, small biofilm biomass
