The bactericidal activity of five antibiotics for Legionella micdadei was determined by the construction of time-kill curves. Erythromycin, rifampin, penicillin G, cephalothin, and gentamicin were bactericidal for L. micdadei at readily achievable concentrations. The minimal bactericidal concentrations, defined as those producing 99.9% killing within 24 h, were: erythromycin, 4.6; rifampin, 0.1...

The response of tolerant Streptococcus sanguis and nontolerant Streptococcus mitis infections to penicillin therapy was compared in the rabbit model of endocarditis. The minimal inhibitory and bactericidal concentrations of penicillin were 0.1 and 0.1 mug/ml, respectively, for S. mitis and 0.05 and 6.2 mug/ml, respectively, for S. sanguis. Time-kill studies done in vitro with penicillin concent...

Crude extracts from olive leaves and arugula seeds were screened for its in vitro antibacterial activity. Antibacterial activity was determined by using disc diffusion method against three bacteria (, Staphylococcus aurous and Bacillus cereus). Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) have been determined. Gallic acid was used as a standard drug for th...
