1 The higher levels of resistance to biapenem, panipenem, and imipenem can be explained by the slow but significant hydrolysis by beta-lactamase, whereas the reduced levels of resistance to BO-2727 and meropenem would be attributable to their stability in the presence of high levels of beta-lactamase and the fact that they cause only low induction of beta-lactamase. Imipenem Beta lactamase Pseudomonas aeruginosa

4 In conclusion, BO-2727 exhibited improved activity against imipenem-resistant P. aeruginosa, probably because of its ability to overcome loss of the D2 porin and beta-lactamase hydrolysis. Imipenem Beta lactamase Pseudomonas aeruginosa
