Azlocillin and mezlocillin: new ureido penicillins.
The activity of azlocillin and mezlocillin, new semisynthetic ureido penicillins, was investigated and compared with that of other known beta-lactam antibiotics. At a concentration of 25 mug/ml, azlocillin inhibited 74% of Enterobacter, 97% of Proteus mirabilis, 64% of Citrobacter, 91% of Pseudomonas aeruginosa, and 82% of Bacteroides strains tested. Mezlocillin inhibited 86% of Shigella, 96% o...
متن کاملThe comparative synergistic activity of amikacin, gentamicin, netilmicin and azlocillin, mezlocillin, carbenicillin and ticarcillin against Serratia marcescens.
The synergistic activities of netilmicin, gentamicin and amikacin combined with carbenicillin, ticarcillin, azlocillin and mezlocillin were investigated against 32 Serratia marcescens isolates. Synergy could be demonstrated by killing curve technique, isobologram plots as susceptibility data with any of the aminoglycosides and penicillins combinations. No antagonism was shown with any of the co...
متن کاملSynergy of azlocillin and mezlocillin combined with aminoglycoside antibiotics and cephalosporins.
Synergistic activity between both azlocillin and mezlocillin and aminoglycosides or cefazolin could be demonstrated by checkerboard dilution, isobologram, and killing curve techniques. Azlocillin and mezlocillin combined with gentamicin, netilmicin, or amikacin were synergistic against Escherichia coli, Klebsiella, Citrobacter, Enterobacter, Serratia, and indole-positive Proteus. Synergy was ob...
متن کاملSynergism of azlocillin, mezlocillin, piperacillin in combination with tobramycin against Klebsiella and Pseudomonas.
Fifty-three clinical isolates of Klebsiella and fifty-one clinical isolates of Pseudomonas aeruginosa, twenty-six of which were carbenicillin-(CARB) resistant, were tested for susceptibility to mezlocillin (MEZ), azlocillin (AZL), and piperacillin (PIP), both alone and in combination with tobramycin (TOB) using the microtiter broth diluent method and an inoculum density of 10(6) CFU/ml. The Kle...
متن کاملComparative study of anti-pseudomonas activity of azlocillin, mezlocillin, and ticarcillin.
The anti-pseudomonas activities of azlocillin and mezlocillin were compared with that of ticarcillin. We measured the minimal inhibitory and minimal bactericidal concentrations of the three drugs against 20 different strains of Pseudomonas aeruginosa and found significantly lower values for azlocillin than for the other two drugs. We then infused 5 g of each drug into 10 volunteers on three con...
