title: Activities of two aminoglycosides and five newer beta-lactam antibiotics: safer alternatives to aminoglycosides?
abstract: Five newer beta-lactam antibiotics and two aminoglycosides were tested on 400 freshly isolated clinically significant organisms from specimens at a district general hospital. All the antibiotics had very broad-spectrum activities but none could cover against all probable pathogens. Latamoxef was the best of all against Bacteroides spp. Aminoglycosides, followed by cefotaxime and ceftizoxime, were best against staphylococci. Tobramycin, followed by ceftazidine and netilmicin, had the best activity against Pseudomonas aeruginosa. Of all 7 antibiotics tested only piperacillin demonstrated activity against Streptococcus faecalis. Cefotaxime and ceftizoxime were the best against Escherichia coli, Klebsiella spp. and most of streptococci. The study demonstrated that safer alternatives to aminoglycosides are now available.
