In Vitro	Cefoxitin has good activity against gram-positive bacteria. The MICs for several gram-positive pathogens are in the range of 1-6 μg/mL[1]. Cefoxitin has shown high efficacy killing B. burgdorferi at concentration of 1.25 µM/mL[3].
In Vivo	Cefoxitin (20 mg/kg; i.p.; daily; for 5 days) effectively kills B. burgdorferi in vivo C3H/HeN mouse model[3]. Animal Model: Four-week-old female C3H/HeN mice[3] Dosage: 20 mg/kg Administration: Intraperitoneal injection, daily, for five consecutive days Result: Had shown high efficacy killing B. burgdorferi in vivo.
