Abstract
Of 40 ready-to-eat salads, 3 (7.5%) were positive for Clostridium difficile by PCR. Two isolates were PCR ribotype 017 (toxin A-, B+), and 1 was PCR ribotype 001. Isolates were susceptible to vancomycin and metronidazole but variably resistant to other antimicrobial drugs. Ready-to-eat salads may be potential sources for virulent C. difficile.
摘要
在40份即食沙拉中，有3份（7.5%）通过聚合酶链反应（PCR）检测出艰难梭菌呈阳性。两份分离株的PCR核糖型为017（毒素A阴性、B阳性），1份为PCR核糖型001。分离株对万古霉素和甲硝唑敏感，但对其他抗菌药物的耐药性各不相同。即食沙拉可能是毒性艰难梭菌的潜在来源。
