Abstract
The antianaerobic activity of tomopenem, a new longer-half-life parenteral carbapenem, was compared with other carbapenems. Tomopenem showed broad activity against 63 reference species. The activity of tomopenem against 293 clinical isolates was potent (MIC(90), 0.06 to 4 microg/ml) and comparable to those of meropenem and doripenem and more potent than that of panipenem.
