Fig. 1From: Do piperacillin/tazobactam and other antibiotics with inhibitory activity against Clostridium difficile reduce the risk for acquisition of C. difficile colonization?Frequency of asymptomatic carriage of toxigenic Clostridium difficile in hospitalized patients, stratified by antibiotic treatment classification. Based upon a modification of the classification scheme of Owens et al. [1], antibiotics on the formulary that were classified as having inhibitory activity against C. difficile included ampicillin, amoxicillin, linezolid, metronidazole, imipenem, meropenem, piperacillin/tazobactam, tigecycline, and tetracyclines. Antibiotics on the formulary that were considered to have poor activity included cephalosporins, ciprofloxacin, and trimethoprim/sulfamethoxazole. Moxifloxacin was classified as having variable activity against C. difficile Back to article page
