Abstract
We described an in vitro 3-dimensional model to study the bactericidal activity of piperacillin (P), tazobactam (T) and amikacin (A) in comb ination against 5 strains of enterobacteria with different resistance patterns to p-lactam antibiotics. A synergy was defined by calculation of Sigma FBCP,T,A = BCp/MBCp + BCT/MBCT + BCA/MBCA and classic Sigma FBCs for each double combination. The therapeutic value of each antibi otic was estimated by comparison of its bactericidal concentrations al one and in double or triple combination.
