[Susceptibility of gram-negative bacterial isolates to six beta-lactam and two aminoglycoside antibiotics at our university hospital].
Susceptibilities of Gram-negative bacterial strains isolated at the University Hospital in 1987 to six beta-Lactam antibiotics (azthreonam cefmetazole, ceftizoxime, latamoxef, aminobenzyl-penicillin and piperacillin) and two aminoglycoside antibiotics (gentamicin and amikacin) were examined by agar dilution and the agar diffusion method. Results obtained from both methods correlated well in most of the strains. Most of the strains belonging to Escherichia coli, Klebsiella oxytoca, Klebsiella pneumoniae and Proteus mirabilis were sensitive to the beta-lactam antibiotics except aminobenzyl-penicillin and piperacillin. They were also sensitive to aminoglycoside antibiotics. Most strains of Citrobacter freundii, Enterobacter cloacae and Serratia marcescens were sensitive to azthreonam, latamoxef and aminoglycosides, but were less sensitive to other beta-lactams. Acinetobacter calcoaceticus was generally resistant to beta-lactams except ceftizoxime, but was sensitive to aminoglycosides. More than half of the strains of Pseudomonas aeruginosa were sensitive to azthreonam, piperacillin and aminoglycoside antibiotics and only latamoxef was active in Pseudomonas maltophilia.
