Abstract

Diarrheagenic Escherichia coli is now recognized as an important cause of diarrhea, hemorrhagic colitis and hemolytic-uremic syndrome (HUS) worldwide. E. coli were isolated from 80 of 356 (22.5%) chicken and chilled chicken products in Korea. Fifteen virulence genes specific for pathogenic E. coli, including Shiga toxin-producing E. coli (STEC), enteropathogenic E. coli (EPEC), enterotoxigenic E. coli (ETEC), enteroinvasive E. coli (EIEC) and enteroaggregative E. coli (EAEC), were examined by multiplex PCR. STEC virulence markers were detected for eaeA (20.0%), escV (21.3%), stx1 (3.8%), ent (2.5%), EHEC-hly (1.3%), stx2 (1.3%), EAEC virulence marker (astA) was detected in 32.5%. ETEC and EIEC were not detected. STEC serotypes O152, O1, O116, O26, O25, O119 and O153 were found in chicken samples. This suggests the importance of diarrheagenic Escherichia coli control in raw chicken and chilled chicken food for food safety.

병원성 대장균군은 전세계적으로 식중독을 발생하는 중요한 병원균으로 알려져 있다. 국내 유통중인 생닭과 조리된 닭가공품 356시료에서 대장균 80균주(22.5%)를 분리하여 병원성 유전자 multiplex PCR를 이용하여 분석한 결과 astA 유전자가 26균주(32.5%)에서 검출되었으며, escV 유전자는 17균주(21.3%) eaeA 유전자는 16균주(20.0%) 검출되었다. 특히 식품에서 문제가 되는 장출혈성 대장균 유전자 stx 1는 3균주(3.8%)와 stx 2, EHEC-hly는 각 1균주(1.3%)에서 검출되었다. 병원성 유전자를 토대로 STEC, EPEC, EHEC, EIEC or EAEC의 병원성 대장균으로 분류한 결과 45균주(56.3%)가 검출되었으며 typical EPEC, EIEC and ETEC의 병원성 대장균은 검출되지 않았다. STEC 병원성 대장균은 O152, O1, O116, O26, O25, O119, O153 혈청형이 분리되었다. 특히 생닭에서 병원성 대장균에 대한 검출률이 높으므로 생닭을 가공 조리 시 교차 오염이 발생하기 않도록 조리 도구, 조리 환경에 대한 철저한 관리가 필요하다고 생각된다.
