摘要：
Clostridium difficile is a leading cause of hospital-acquired diarrhoea and represents a major challenge for healthcare providers. Due to the decreasing efficacy and associated problems of antibiotic therapy there is a need for synergistic and alternative treatments. In this study we investigated the use of a specific bacteriophage, Phi CD27, in a human colon model of C difficile infection. Our findings demonstrate a significant reduction in the burden of C difficile cells and toxin production with phage treatment relative to an untreated control, with no detrimental effect on commensal bacterial populations. The results demonstrate the potential of phage therapy, and highlight the limitations of using phages that have lysogenic capacity. (C) 2013 Elsevier Ltd. All rights reserved.
