Title: Comparative in vitro activity of moxalactam, cefotaxime, cefoperazone, piperacillin, and aminoglycosides against gram-negative bacilli. Author: Kurtz TO, Winston DJ, Hindler JA, Young LS, Hewitt WL, Martin WJ. Journal: Antimicrob Agents Chemother; 1980 Oct; 18(4):645-8. PubMed ID: 6255864. Abstract: The in vitro activities of four new beta-lactam antimicrobial agents (moxalactam, cefotaxime, cefoperazone, and piperacillin) and the aminoglycosides against 744 recent clinical isolates of facultative gram-negative bacilli were compared simultaneously by the agar dilution method. The major in vitro difference of these newer beta-lactam compounds appeared to be their antipseudomonal activity; cefoperazone was the most active, whereas cefotaxime had the least potency. The aminoglycosides, however, had the most effective in vitro activity on a weight basis against Pseudomonas aeruginosa.[Abstract] [Full Text] [Related] [New Search]
