Abstract
Clostridium difficile was isolated from 1.8% (7/393) of retail pork samples obtained from 4 Canadian provinces. Five ribotypes and 3 toxinotypes were identified. Three isolates were indistinguishable from the international outbreak strain ribotype 027 and were toxinotype III. Although the implications for food safety practices remain elusive, the frequency of toxigenic isolates and isolates indistinguishable from known human pathogenic strains suggests contaminated pork may be a source of C. difficile in humans.
摘要
从加拿大4个省份采集的393份零售猪肉样本中，1.8%（7份）分离出艰难梭菌。鉴定出5种核糖型和3种毒素型。3株分离菌与国际暴发菌株核糖型027无法区分，且为毒素型III。尽管对食品安全措施的影响尚不清楚，但产毒分离菌以及与已知人类致病菌株无法区分的分离菌的出现频率表明，受污染的猪肉可能是人类艰难梭菌的一个来源。
