In vitro activity of ceftizoxime against Bacteroides fragilis: comparison with benzylpenicillin, cephalothin, and cefoxitin.
Minimum inhibitory concentrations of ceftizoxime for seven clinical isolates of Bacteroides fragilis were found to be markedly affected by inoculum size; the very low minimum inhibitory concentration values (less than or equal to 0.25 microgram/ml) obtained in tests with most strains were not sustained when the inoculum was raised 100-fold. Benzylpenicillin and cephalothin were also affected by...
متن کاملActivity of ceftizoxime and comparative compounds against Bacteroides fragilis in a mouse model of anaerobic infection.
A new mouse model of anaerobic infection with Bacteroides fragilis alone or in a mixed infection with Escherichia coli is described. It is established by implantation under the skin of a filter paper disk saturated with the appropriate bacterial suspension. The penetration of antibiotics into the implantation site can be detected by assaying the disk. The local infection can be both standardize...
متن کاملComparative in vitro activity of REP3123 against Clostridium difficile and other anaerobic intestinal bacteria.
OBJECTIVES The aim of this study was to determine the anaerobic spectrum of activity of REP3123, a novel diaryldiamine that inhibits bacterial methionyl-tRNA synthetases in Gram-positive bacteria. METHODS Fifty recent clinical isolates of Clostridium difficile from patients diagnosed with C. difficile infection and 223 other intestinal normal flora anaerobes were tested for their susceptibili...
متن کاملIn vitro activity of cefbuperazone against anaerobic bacteria.
The in vitro activity of cefbuperazone was compared with that of cefoxitin, moxalactam, and piperacillin against 305 strains of anaerobic bacteria. Piperacillin was the most active overall, inhibiting 97% of all anaerobes tested at 128 micrograms/ml. Cefbuperazone had poor activity against the Bacteroides fragilis group and Clostridium difficile (43 and 0% susceptible, respectively) but good ac...
متن کاملIn vitro activity of sodium fusidate against anaerobic bacteria.
The microtiter broth dilution method was employed to determine the in vitro susceptibility of 525 recent clinical isolates of anaerobic bacteria to sodium fusidate. The minimal inhibitory concentrations of sodium fusidate ranged from </=0.06 to 1.0 mug/ml for 155 strains of anaerobic gram-positive rods and 130 strains of anaerobic gram-positive cocci. Minimal inhibitory concentrations ranging f...
