BO3482

Animal experiment:

In the thigh infection model, four immunosuppressed mice are used per group. An overnight culture of MRSA BB6294 in tryptic soy broth is washed and resuspended in fresh tryptic soy broth. Of this suspension, 0.1 mL is injected into the right thighs of slightly anesthetized mice. The mice receive two doses of drug subcutaneously 2 and 6 h after injection of the test organisms by the following treatment regimens: 10, 20,or 40 mg of BO3482 with 40 mg of cilastatin per kg per dose; 10, 20, or 40 mg of vancomycin per kg per dose; or 40 mg of imipenem with 40 mg of cilastatin per kg per dose. Four hours after the last treatment, the thigh muscles are removed and immediately homogenized in ice-cold 0.9% NaCl with a tissue homogenizer[2].
