One poster summarized studies conducted by FleurirABX on a wide range of gram-negative pathogens, entitled “In-vitro activity of a fosfomycin-trimethoprim-sulfamethoxazole combination against 3rd-generation cephalosporin, beta-lactam-beta-lactamase inhibitor combination, carbapenem, aminoglycoside, tigecycline, polymyxin B, and/or colistin-resistant Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, and Acinetobacter baumanniiclinical isolates.” 

The second poster summarized studies conducted by FleurirABX on a wide range of gram-positive pathogens, entitled “In-vitro activity of a fosfomycin-trimethoprim-sulfamethoxazole antibacterial combination against methicillin-resistant Staphylococcus aureus and Enterococcus spp.”
