title: In-vitro antibacterial activity of AMA-1080.
abstract: The in-vitro antibacterial activity of AMA-1080 against both Gram-positive and Gram-negative clinical isolates was studied in comparison with that of aztreonam, cefotaxime, ceftazidime and cefoperazone. AMA-1080 showed a potent antibacterial activity against Gram-negative bacteria, particularly, the strains of Enterobacteriaceae. In addition, AMA-1080 inhibited the strains of genus Pseudomonas at the low concentrations. However, AMA-1080 showed less active against Gram-positive bacteria. It was found that AMA-1080 was highly resistant to hydrolysis by both chromosomal and plasmid-mediated beta-lactamases.
