Ceftobiprole and ceftobiprole medocaril did not promote growth of or toxin production by Clostridium difficile in mouse cecal contents, whereas ceftazidime, cefoxitin, ceftriaxone, cefotaxime, and ertapenem did. The relatively low propensity of ceftobiprole to promote C. difficile was attributable to inhibitory activity against C. difficile and sparing of anaerobic microflora.
头孢洛林和头孢洛林酯在小鼠盲肠内容物中既不促进艰难梭菌生长也不促进其产毒,而头孢他啶、头孢西丁、头孢曲松、头孢噻肟和厄他培南则有此作用。头孢洛林相对低的促艰难梭菌生长能力归因于其对艰难梭菌的抑制活性和对厌氧微生物群落的保护作用。
