The activity of cefotaxime, either alone or combined with an aminoglycoside, was determined against 50 isolates of Pseudomonas aeruginosa, of which 50, 33, and 10 were resistant to gentamicin, tobramycin, and amikacin, respectively. Cefotaxime inhibited 34 isolates at a concentration of 16 microgram/ml and all isolates at 128 microgram/ml. The combinations of cefotaxime with gentamicin, tobramycin, and amikacin were synergistic against 30, 17, and 9 isolates, respectively, and no antagonism was observed with any combination. Synergism was obtained at clinically significant antibiotic concentrations for nine isolates with cefotaxime-gentamicin, five isolates with cefotaxime-tobramycin, and nine isolates with cefotaxime-amikacin.
测定了头孢噻肟单独使用或与一种氨基糖苷类药物联合使用时对50株铜绿假单胞菌的活性,其中分别有50株、33株和10株对庆大霉素、妥布霉素和阿米卡星耐药。头孢噻肟在浓度为16微克/毫升时抑制了34株菌株,在128微克/毫升时抑制了所有菌株。头孢噻肟与庆大霉素、妥布霉素和阿米卡星的联合用药分别对30株、17株和9株菌株具有协同作用,且未观察到任何联合用药有拮抗作用。对于9株使用头孢噻肟-庆大霉素联合用药的菌株、5株使用头孢噻肟-妥布霉素联合用药的菌株和9株使用头孢噻肟-阿米卡星联合用药的菌株,在具有临床意义的抗生素浓度下获得了协同作用。
