Approximately 15 to 35% of patients with a first episode of Clostridium difficile-associated diarrhea relapse within 2 months. Between 1994 and 1997, strains from 93 hospitalized patients with C. difficile recurrences were fingerprinted by using both serotyping and PCR-ribotyping. The results showed that 48.4% of clinical recurrences were, in fact, reinfections with a different strain of C. difficile. Rates of clinical recurrences could therefore be reduced by implementing strict isolation precautions.
首次发作艰难梭菌相关性腹泻的患者中,约15%至35%会在2个月内复发。1994年至1997年期间,对93例艰难梭菌复发的住院患者的菌株进行了血清分型和PCR核糖体分型指纹图谱分析。结果显示,实际上48.4%的临床复发是由不同菌株的艰难梭菌再次感染所致。因此,通过实施严格的隔离预防措施可以降低临床复发率。
