Cefoxitin is a broad-spectrum, second-generation cephalosporin with antibacterial activity. Cefoxitin is effective against a wide variety of infections caused by gram-positive or gram-negative aerobes as well as by anaerobic bacteria[1][2].

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].

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]
