Susceptibilities of Penicillin- and Erythromycin-Susceptible and -Resistant Pneumococci to HMR 3647 (RU 66647), a New Ketolide, Compared with Susceptibilities to 17 Other Agents
ABSTRACT Susceptibility of 230 penicillin- and erythromycin-susceptible and -resistant pneumococci to HMR 3647 (RU 66647), a new ketolide, was tested by agar dilution, and results were compared withExpand
Susceptibilities of Streptococcus pneumoniae and Haemophilus influenzae to 10 Oral Antimicrobial Agents Based on Pharmacodynamic Parameters: 1997 U.S. Surveillance Study
ABSTRACT The susceptibilities of Streptococcus pneumoniae (1,476 strains) and untypeable Haemophilus influenzae (1,676 strains) to various oral β-lactam, macrolide-azalide, and fluoroquinoloneExpand
Activity of Meropenem with and without Ciprofloxacin and Colistin against Pseudomonas aeruginosa and Acinetobacter baumannii
ABSTRACT Time-kill synergy studies showed that at 24 h, subinhibitory meropenem and ciprofloxacin concentrations of 0.06 to 128 and 0.03 to 32 μg/ml, respectively, showed synergy against 34/51Expand
Antipneumococcal Activity of ABT-773 Compared to Those of 10 Other Agents
ABSTRACT MICs, time-kills, and postantibiotic effects (PAEs) of ABT-773 (a new ketolide) and 10 other agents were determined against 226 pneumococci. Against 78 ermB- and 44mefE-containing strains,Expand
Activities of Tizoxanide and Nitazoxanide Compared to Those of Five Other Thiazolides and Three Other Agents against Anaerobic Species
ABSTRACT Agar dilution was used, and MICs of metronidazole, tizoxanide, nitazoxanide, denitrotizoxanide, RM 4803, RM 4807, RM 4809, RM 4819, amoxicillin-clavulanate, and clindamycin were measuredExpand
In Vitro Development of Resistance to Five Quinolones and Amoxicillin-Clavulanate in Streptococcus pneumoniae
ABSTRACT The ability of 50 sequential subcultures in subinhibitory concentrations of ciprofloxacin, levofloxacin, grepafloxacin, sparfloxacin, trovafloxacin, and amoxicillin-clavulanate to select forExpand
Susceptibilities of 123 strains of Xanthomonas maltophilia to eight beta-lactams (including beta-lactam-beta-lactamase inhibitor combinations) and ciprofloxacin tested by five methods.
This study evaluated the susceptibility of 123 Xanthomonas maltophilia strains to ticarcillin, ticarcillin-clavulanate, ampicillin, amoxicillin-clavulanate, ampicillin-sulbactam, piperacillin,Expand
Placental Microbiology and Histology and the Pathogenesis of Chorioamnionitis
The present study was undertaken to determine the proportion of cases of Chorioamnionitis that was caused by micro-biologic agents. Seventy-five placentas were processed to isolate aerobic andExpand
Antipneumococcal Activities of Gemifloxacin Compared to Those of Nine Other Agents
ABSTRACT The activities of gemifloxacin compared to those of nine other agents was tested against a range of penicillin-susceptible and -resistant pneumococci by agar dilution, microdilution,Expand
Activity of Telavancin against Staphylococci and Enterococci Determined by MIC and Resistance Selection Studies
ABSTRACT This study used CLSI broth microdilution to test the activity of telavancin and comparator antimicrobial agents against 67 methicillin (meticillin)-resistant Staphylococcus aureus (MRSA)Expand
