概要 We compared the potency of SMP-601, a novel carbapenem, with that of vancomycin in a murine model of hematogenous bronchopneumonia infection caused by methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-intermediate S. aureus (VISA). The MICs of SMP-601 and vancomycin against MRSA were 2 and 1 mug/ml, respectively, while those against VISA were 2 and 8 mug/ml, respectively. Treatment with SMP-601 resulted in a significant decrease in the number of viable bacteria in the MRSA infection model (control, 100 mg/kg vancomycin, and 100 mg/kg SMP-601, 8.42 +/- 0.50, 5.29 +/- 0.71, and 5.50 +/- 0.58 log CFU/lung, respectively,) and in the VISA infection model (control, 100 mg/kg vancomycin, and 100 mg/kg SMP-601, 9.64 +/- 0.63, 8.72 +/- 0.45, 7.42 +/- 0.14 log CFU/lung) (mean +/- standard error of the mean). The survival rate in the VISA infection model treated with SMP-601 (70%) was significantly higher than those in the other two groups (20% for vancomycin and 0% for control; P<0.05). Histopathological examination revealed that inflammatory changes in the SMP-601-treated group were less marked than in the other two groups. The results of pharmacokinetic-pharmacodynamic an
