In vitro activity of the newer quinolones compared with the classic ones and tobramycin.
Boquet Jimenez E, Dalet Escriba F, Caballe L.
The halogenated substitution of quinolone derivatives has given rise to a new group of substances called newer quinolones, which possess extraordinary antibacterial activity in vitro. The aim of our study was to compare the effect of the newer quinolones ciprofloxacin (CIP), norfloxacin (NOR) and enoxacin (ENO) with that of the classical ones nalidixic acid (NA), oxolinic acid (OX) and pipemidic acid (PIP) and with a widely-used aminoglycoside tobramycin (TBR). This was tested on 2,263 strains from clinical isolations. Evaluating the effect of the least active substances as a unit, we generally found the MIC90s to be of the following order: (Formula: see text). The remaining groups among the antibiotics studied are ordered identically, the most potent being the newer quinolones in the following order: CIP is at least four times superior to NOR, which in turn is at least twice as effective as ENO for gram-positive organisms, but only 1.2 times for gram-negative bacilli.

The in vitro activity of fleroxacin was compared to that of ciprofloxacin, ofloxacin and three broad-spectrum beta-lactams against 159 clinical isolates using the E-Test. Fleroxacin, ciprofloxacin, and ofloxacin were all active against Enterobacteriaceae with 93, 98 and 94% susceptibility, respectively. For other gram-negative strains, 81% were susceptible to fleroxacin and ofloxacin and 98% to ciprofloxacin. With regard to gram-positive strains, 72% were susceptible to fleroxacin, 83% to ciprofloxacin and 78% to ofloxacin. The broad antibacterial activity suggests that fleroxacin may be an alternative in the treatment of various infections, particularly in light of its favorable pharmacokinetics.

Comparative activity of newer antibiotics against gram-negative bacilli.
Knapp CC, Washington JA.
The in vitro activities of cefoperazone, cefotaxime, ceftriaxone, ceftazidime, azlocillin, mezlocillin, piperacillin, ticarcillin/clavulanate, aztreonam, imipenem, and ciprofloxacin were concurrently determined against over 1,000 isolates of gram-negative bacilli from clinical specimens of patients at the Cleveland Clinic. Cephalosporins, penicillins, and aztreonam were active against species of Enterobacteriaceae other than Citrobacter freundii, Enterobacter aerogenes, and Enterobacter cloacae. Ceftazidime was the most active cephalosporin against Pseudomonas aeruginosa. Against the Enterobacteriaceae, the rank order of activity of penicillins was ticarcillin/clavulanate greater than piperacillin greater than mezlocillin greater than azlocillin. Against P. aeruginosa, the rank order of activity of penicillins was piperacillin greater than ticarcillin/clavulanate greater than azlocillin greater than mezlocillin. Aztreonam was less active v P. aeruginosa than ceftazidime, cefoperazone, or piperacillin. The most active antimicrobials against all isolates tested were imipenem and ciprofloxacin.
